Streszczenie:

Leaderless replication allows any replica to handle any type of request to achieve read scalability and high availability for distributed data stores. However, this entails burdensome coordination overhead of replication protocols, degrading write throughput. In addition, the data store still requires coordination for membership changes, making it hard to resolve server failures quickly. To this end, we present NetLR, a replicated data store architecture that supports high performance, fault tolerance, and linearizability simultaneously. The key idea of NetLR is moving the entire replication functions into the network by leveraging the switch as an on-path in-network replication orchestrator. Specifically, NetLR performs consistency-aware read scheduling, high-performance write coordination, and active fault adaptation in the network switch. Our in-network replication eliminates inter-replica coordination for writes and membership changes, providing high write performance and fast failure handling. NetLR can be implemented using programmable switches at a line rate with only 5.68% of additional memory usage. We implement a prototype of NetLR on an Intel Tofino switch and conduct extensive testbed experiments. Our evaluation results show that NetLR is the only solution that achieves high throughput and low latency and is robust to server failures.

Traditional file systems have some shortages in storing small files, such as randomness of data layout, waste of disk space and lack of inode resources. In this thesis, a log-structured file system named LevelFS based on LevelDB is presented. By setting the write buffer, it can make disk randomized writes of small files into disk sequential writes, and reduce the distance of related data, so as to improve the read and write performance of file system. Experiments show that LevelFS can greatly improve read and write performance of small files without affect the large ones.

AbstractOblivious RAMs (ORAMs) allow a client to access data from an untrusted storage device without revealing the access patterns. Typically, the ORAM adversary can observe both read and write accesses. Write-only ORAMs target a more practical, multi-snapshot adversary only monitoring client writes – typical for plausible deniability and censorship-resilient systems. This allows write-only ORAMs to achieve significantly-better asymptotic performance. However, these apparent gains do not materialize in real deployments primarily due to the random data placement strategies used to break correlations between logical and physical names-paces, a required property for write access privacy. Random access performs poorly on both rotational disks and SSDs (often increasing wear significantly, and interfering with wear-leveling mechanisms).In this work, we introduce SqORAM, a new locality-preserving write-only ORAM that preserves write access privacy without requiring random data access. Data blocks close to each other in the logical domain land in close proximity on the physical media. Importantly, SqORAM maintains this data locality property over time, significantly increasing read throughput.A full Linux kernel-level implementation of SqORAM is 100x faster than non locality-preserving solutions for standard workloads and is 60-100% faster than the state-of-the-art for typical file system workloads.

Streszczenie:

Nonvolatile memory (e.g., Phase Change Memory) blurs the boundary between memory and storage and it could greatly facilitate the construction of in-memory durable data structures. Data structures can be processed and stored directly in NVRAM. To maintain the consistency of persistent data, logging is a widely adopted mechanism. However, logging introduces write-twice overhead. This paper introduces an optimized write-combined logging to reduce the writes to NVRAM log. By leveraging the fast-read and byte-addressable features of NVRAM, we can perform a read-and-compare operation before writes and thus issue writes in a finer-grained way. We tested our system on the benchmark suit STAMP which contains real-world applications. Experiment results show that our system can reduce the writes to NVRAM by 33%–34%, which can help extend the lifetime of NVRAM and improve performance. Averagely our system can improve performance by 7%–11%.

Streszczenie:

Multilevel cell (MLC) phase change memory (PCM) shows great potential in terms of capacity and cost compared with single-level cell (SLC) PCM by storing multiple bits in one physical PCM cell. However, poor write performance is a huge challenge for MLC PCM. In general, write latency of MLC PCM is 10 to 100X longer compared with DRAM technology. Considerable write latency greatly degrades the overall system performance and restricts the application of MLC PCM. Actually, several chips compose a memory DIMM to match the wide interface of data bus. The data of a write request, i.e., a cache line block, are distributed to multiple PCM chips. As a result, the write service time is determined by the chips with the most data amount. Conventional PCM write schemes do not care for the modified-byte distribution among PCM chips and it just waits for the completion of the chip with the most amount of data. However, it is observed that (1) the conventional PCM write scheme suffers from unbalanced modified-byte distribution that some PCM chips bear too many modified bytes while some chips are kept idle for long times. (2) The modified-byte distribution shows some unique patterns that some bytes are changed more frequently compared with others. (3) MLC PCM shows significant asymmetry considering only MSB or LSB transitions. Based on these observations, in order to solve the poor write problem of PCM, this article presents a novel PCM write scheme called PCM-2R. The key ideas behind our proposed scheme are to reshape the data to evenly distribute the cache line blocks among all chips based on their modified-byte distribution pattern to avoid unbalanced distribution and then remap modified bytes to fast region after decoupling MLC PCM cells considering the state transition asymmetries. The evaluation results show that PCM-2R achieves 51% read latency reduction, 37% write latency reduction, 1.9X IPC improvement, 41% running time reduction, 2.2X throughout improvement, and 52% energy reduction compared with the baseline. Moreover, compared with the state-of-the-art write schemes, PCM-2R achieves 0.2X more IPC improvement and 0.2X throughout improvement.

Devices in IoE (Internet of Everything) environment generate massive data from various sensors. To store and process the rapidly incoming large-scale data, SSDs are used for improving performance and reliability of storage systems. However, they have typical problem called write amplification which is caused by out-of-place updates characteristics. As the write amplification increases, it degrades I/O performance and shortens SSDs' lifetime. This paper presents a new approach to reduce write amplification of SSD arrays. To solve the problem, this paper proposes a new parity update scheme, called LPUS. LPUS transforms random parity updates to sequential writes with additional log blocks in SSD arrays by using parity logs and lazy parity updates. The experimental results show that, LPUS reduces write amplification up to 37% and the number of erases up to 50% with the reasonable size of log space.

Random writes limit the application of SSDs significantly because of their poor latency and high garbage collection overhead. Traditional page-based and block-based buffer management algorithms cannot achieve both high buffer hit ratio and good destage sequentiality at the same time. In this paper, we propose a hybrid scheme called the group-based buffer management (GBBM). To improve buffer hit ratio and decrease write/erase counts, GBBM divides buffer space into Page Region and Group Region. The frequently accessed data pages are placed at the Page Region, while infrequently accessed random written data are grouped in the Group Region. GBBM has been evaluated extensively through simulations. The write counts of GBBM show an average decrease of 12.7% compared with page-level buffer scheme. Compared with hybrid buffer management such as CBM, GBBM decreases the average write/erase count by 14.3%/12.1%. The write hit ratio of GBBM shows a 4.5% improvement as compared with PAB. The proposed GBBM can significantly reduce the number of write operations while maintaining a relatively high buffer hit ratio.

This study deals with the student’s ability in writing. Writing is one of the four English language skills which is taught in Indonesia starting from Senior High School. Furthermore, for the students, writing has become a necessary skill to master since it frequently determines their academic success. Therefore, every students has to learn how to write effectively. The scope of the study is limited to the effect of using flash cards in developing student’s ability to write narrative paragraphs. The purpose of this study was to find out whether students, were able to write a narrative paragraph or not. There were 26 students selected with randomly. In choosing the sample from the population, the writer uses lottery technique. The instrument for collecting data was writing test. The data were obtained by administering a self made test as the instruments for collecting the data and were considered in terms of validity and reliability. The method of collecting data plays an important role in conducting any kind of research in order that the result of the study will be valid. To collect the data, the writer used written test to the student as test instrument. Students as observed participants were tested by asking them to write narrative paragraphs based on the flash cards. The results of the writing ability test were analyzed by converting the student’s achievement into percentages. The percentage of the score was obtained based on the five criteria components of writing by using the formula below: The score were evaluated by using Jacob’s (1983) criteria in writing namely: Content, Organization, Vocabulary, Language in Use and Mechanic. After analyzing the data, it was found that 46,16 % or 12 students got the score percentage, lower than 75 %. Therefore, it can be calculated that the students were unable in developing to write narrative paragraph.

Streszczenie:

STT-RAM (Spin-Transfer Torque Random Access Memory) appears to be a viable alternative to SRAM-based on-chip caches. Due to its high density and low leakage power, STT-RAM can be used to build massive capacity last-level caches (LLC). Unfortunately, STT-RAM has a much longer write latency and a much greater write energy than SRAM. Researchers developed hybrid caches made up of SRAM and STT-RAM regions to cope with these challenges. In order to store as many write-intensive blocks in the SRAM region as possible in hybrid caches, an intelligent block placement policy is essential. This paper proposes an adaptive block placement framework for hybrid caches that incorporates metadata embedding (ADAM). When a cache block is evicted from the LLC, ADAM embeds metadata (i.e., write intensity) into the block. Metadata embedded in the cache block are then extracted and used to determine the block’s write intensity when it is fetched from main memory. Our research demonstrates that ADAM can enhance performance by 26% (on average) when compared to a baseline block placement scheme.

Streszczenie:

For a write request, today's flash storage cannot distinguish the logical object it comes from ( e.g. , SSTables in RocksDB). In such object-oblivious flash devices, concurrent writes from different objects are simply packed in their arrival order to flash memory blocks; hence data pages from multiple objects with different lifetimes are multiplexed onto the same flash blocks. This multiplexing incurs write amplification, worsening the performance. Tackling the multiplexing problem, we propose a novel interface for flash storage, FlashAlloc. It is used to pass the logical address ranges of objects to the underlying flash device and thus to enlighten the device to stream writes by objects. The object-aware flash storage can now de-multiplex concurrent writes from multiple objects with distinct deathtimes into per-object dedicated flash blocks. In essence, the interface enables the per-object fine-grained write streaming. Given that popular data stores tend to separate writes by logical objects, we can achieve, compared to the existing solutions, transparent streaming just by calling FlashAlloc upon object creation. Also, FlashAlloc is adaptive to workload changes, and liberates the stream conflicts in the multi-tenant environment. Our experimental results using an open-source SSD prototype demonstrate that FlashAlloc can reduce the device-level write amplification factor (WAF) under RocksDB, F2FS, and MySQL by 1.5, 2.5, and 0.3, respectively and improve their throughput by 2.7x, 1.8x, and 1.2x, respectively. Also, FlashAlloc can mitigate the WAF interference among tenants: when running RocksDB and MySQL together on the same SSD, FlashAlloc reduced WAF from 2.5 to 1.6 and doubled their throughputs.

Hybrid storage servers combining solid-state drives (SSDs) and hard-drive disks (HDDs) provide cost-effectiveness and μs-level responsiveness for applications. However, observations from cloud storage system Pangu manifest that HDDs are often underutilized while SSDs are overused, especially under intensive writes. It leads to fast wear-out and high tail latency to SSDs. On the other hand, our experimental study reveals that a series of sequential and continuous writes to HDDs exhibit a periodic, staircase-shaped pattern of write latency, i.e., low (e.g., 35 μs), middle (e.g., 55 μs), and high latency (e.g., 12 ms), resulting from buffered writes within HDD’s controller. It inspires us to explore and exploit the potential μs-level IO delay of HDDs to absorb excessive SSD writes without performance degradation. We first build an HDD writing model for describing the staircase behavior and design a profiling process to initialize and dynamically recalibrate the model parameters. Then, we propose a Buffer-Controlled Write approach (BCW) to proactively control buffered writes so that low- and mid-latency periods are scheduled with application data and high-latency periods are filled with padded data. Leveraging BCW, we design a mixed IO scheduler (MIOS) to adaptively steer incoming data to SSDs and HDDs. A multi-HDD scheduling is further designed to minimize HDD-write latency. We perform extensive evaluations under production workloads and benchmarks. The results show that MIOS removes up to 93% amount of data written to SSDs, reduces average and 99 th -percentile latencies of the hybrid server by 65% and 85%, respectively.

An important role of display visual design is advertising and advertising communication, which is an integrated medium, that is, a medium for communicating information. Visual communication design is the most direct way of information transmission in modern society. In today’s increasingly complex and diversified information, visual communication design has been more and more widely used in terms of form and function. On the display platform, the use of visual elements and the expression of visual communication design allows us to examine the different spatial experiences that visual communication design brings to people from a new perspective and adjust the way it is communicated, so as to find a scientific expression. This paper focused on the role of visual communication in display design and discussed its specific application in display design. The use of visual elements in the display space provides a new visual platform for spatial information, making the space design more connotative and cultural. For the smooth experience of media fusion design, it is necessary to ensure that information can be transmitted quickly and smoothly in every link of its processing. In the data write throughput experiment of the microperceptual data layer, the maximum write speed increased by 85.2% compared with the direct write method using the TSBPS method. The findings demonstrated that the IOT-HSQM model’s strategy of first queuing and then segmentation writes may more effectively fulfill the demands of high bandwidth than straight data transmission to HDFS (Hadoop Distributed File System).

A novel six-transistor static random-access memory (6T SRAM) cell is proposed in this paper for enhancing the data stability and write ability as compared to the conventional memory circuits. Asymmetrically gate overlapped / underlapped FinFETs are employed as bitline access transistors in the proposed SRAM cell. The strength of the asymmetrical bitline access transistors are weakened during read operations. Furthermore, voltage transfer characteristics (VTCs) of cross-coupled inverters have narrower transition regions in the new SRAM cell as compared to the conventional SRAM cells. The proposed SRAM cell thereby provides stronger read data stability as compared to the conventional symmetrical SRAM cells. The strength of bitline access transistors are enhanced during write operations as the direction of current flow is reversed in the new asymmetrical SRAM cell. The power supply voltage of a selected word floats during write operations. The write voltage margin is thereby significantly increased with the proposed SRAM cell as compared to the conventional SRAM cells. The read data stability and write ability are both enhanced by up to 51.7% and 65.5%, respectively, with the proposed SRAM cell as compared to the conventional symmetrical six-FinFET SRAM cells in a 15[Formula: see text]nm FinFET technology.

Furthermore, the article also describes the concept and assumptions about the temporal graph database, including a proposal of two methods for representing temporal data in graph databases. Full write method assumes creating a new database object for each state of being. While incremental method writes only such features and relationships that were subject to change. Regardless of the data write method used, the data may be returned in a historically unordered or ordered manner. The article outlines assumptions for both methods of representing data.

Seiring dengan kemajuan teknologi informasi dan laju perkembangannya yang semakin pesat mendorong adanya perkembangan distributed database. Tujuan diterapkannya sistem informasi berbasis web yaitu agar user dapat mengakses informasi dimanapun dan kapanpun. Namun, semakin bertambahnya data, membuat sistem membutuhkan waktu lama dalam melakukan display data. Untuk menanganinya dibuatlah sebuah buffer display yang biasa kita sebut dengan istilah Data Mart Query (DMQ). Namun, ternyata DMQ tersebut pun mempunyai kendala yaitu data menjadi tidak update sehingga data yang ditampilkan bukanlah data realtime, sementara data selalu berubah setiap saat diberbagai user dan client. Untuk itu diperlukan sebuah solusi baru melalui metode write validation. Walaupun display data bukanlah data update, namun dengan metode ini sistem harus melakukan proses validation terlebih dahulu, sebelum eksekusi dijalankan. Dalam artikel ini, diindentifikasi 2 masalah yang dihadapi dalam suatu sistem terdistribusi khususnya masalah dalam menampilkan view data ke pengguna dengan cepat, namun tetap aman saat dieksekusi, definisi dari write validation, 3 ciri khas write validation, keuntungan dan kelemahan dari write validation, algoritma serta manfaat dari metode ini. Pada implementasinya, ditampilkan listing program yang ditulis menggunakan script ASP. Kontribusi metode write validation dalam distributed database system merupakan suatu solusi yang sangat membantu menjaga keamanan database saat dilakukan eksekusi, walaupun data yang ditampilkan merupakan data buffer yang digunakan demi menjaga standard TWT (Tolerable Wait Time).

The study was carried out at SMPN 14 Bengkulu City, in Padang Nangka, Singgaran Pati District, and the sample consisted of 26 class VII students who were chosen at random. The research tool was a descriptive (essay-style) test with five questions based on markers of argumentation skill (claims, data, warrants, backing, rebuttal, and qualifiers). An analysis was done based on the argumentative element in the student responses. According to the findings, 100% of students wrote claims, 19% wrote down data, 12% wrote warrants, 4% were able to write backings, and 0% wrote rebuttals and qualifiers. Overall, it can be said that most students can write claims, but they are starting to have trouble presenting data, warrants, backups, rebuttals, and qualifiers. Teachers can use the proportion of a student's initial reasoning skills as a benchmark to decide on designs or learning activities in the future that will not only focus on helping students understand topics but will also help them build or train their thinking skills.

Recently, the emerging technology known as Interlaced Magnetic Recording (IMR) has been receiving widespread attention from both industry and academia. IMR-based disks incorporate interlaced track layouts and energy-assisted techniques to dramatically increase areal densities. The interlaced track layout means that in-place updates to the bottom track require rewriting the adjacent top track to ensure data consistency. However, at high disk utilization, frequent track rewrites degrade disk performance. To address this problem, we propose a solution called Balloon to reduce the frequency of track rewrites. First, an adaptive write interference data placement policy is introduced, which judiciously places data on tracks with low rewrite probability to avoid unnecessary rewrites. Next, an on-demand data shuffling mechanism is designed to reduce user-requests write latency by implicitly migrating data and promptly swapping tracks with high update block coverage to the top track. Finally, a write-interference-free persistent buffer design is proposed. This design dynamically adjusts buffer admission constraints and selectively evicts data blocks to improve the cooperation between data placement and data shuffling. Evaluation results show that Balloon significantly improves the write performance of IMR-based disks at medium and high utilization compared with state-of-the-art studies.

Flash-based storage is replacing disk for an increasing number of data center applications, providing orders of magnitude higher throughput and lower average latency. However, applications also require predictable storage latency. Existing Flash devices fail to provide low tail read latency in the presence of write operations. We propose two novel techniques to address SSD read tail latency, including Redundant Array of Independent LUNs (RAIL) which avoids serialization of reads behind user writes as well as latency-aware hot-cold separation (HC) which improves write throughput while maintaining low tail latency. RAIL leverages the internal parallelism of modern Flash devices and allocates data and parity pages to avoid reads getting stuck behind writes. We implement RAIL in the Linux Kernel as part of the LightNVM Flash translation layer and show that it can reduce read tail latency by 7× at the 99.99th percentile, while reducing relative bandwidth by only 33%.

Most SSDs (solid-state drives) use an internal DRAM (Dynamic Random Access Memory) to improve the I/O performance and extend SSD lifespan by absorbing write requests. However, this volatile memory does not guarantee the persistence of buffered data in the event of sudden power-off. Therefore, highly reliable enterprise SSDs employ power-loss-protection (PLP) logic to ensure the durability of buffered data using the back-up power of capacitors. The SSD must provide enough capacitors for the PLP in proportion to the size of the volatile buffer. Meanwhile, emerging ZNS (Zoned Namespace) SSDs are attracting attention because they can support many I/O streams that are useful in multi-tenant systems. Although ZNS SSDs do not use an internal mapping table unlike conventional block-interface SSDs, a large write buffer is required to provide many I/O streams. The reason is that each I/O stream needs its own write buffer for write buffering where the host can allocate separate zones to different I/O streams. Moreover, the larger capacity and more I/O streams the ZNS SSD supports, the larger write buffer is required. However, the size of the write buffer depends on the amount of capacitance, which is limited not only by the SSD internal space, but also by the cost. Therefore, in this paper, we present a set of techniques that significantly reduce the amount of capacitance required in ZNS SSDs, while ensuring the durability of buffered data during sudden power-off. First, we note that modern file systems or databases have their own solutions for data recovery, such as WAL (Write-ahead Log) and journal. Therefore, we propose a selective power-loss-protection method that ensures durability only for the WAL or journal required for data recovery, not for the entire buffered data. Second, to minimize the time taken by the PLP, we propose a balanced flush method that temporarily writes buffered data to multiple zones to maximize parallelism and preserves the data in its original location when power is restored. The proposed methods are implemented and evaluated by modifying FEMU (QEMU-based Flash Emulator) and RocksDB. According to experimental results, the proposed selective-PLP reduces the amount of capacitance by 50 to 90% while retaining the reliability of ZNS SSDs. In addition, the balanced flush method reduces the PLP latency by up to 96%.

The Labor Working Status Monitoring (LWSM) Model that incorporates the WRITE and the industry benchmark data was developed through the five steps to enhance labor producitivty in bridge construction operations. The first step of the development process was to conduct a literature review, followed by the second step which was to develop the WRITE. During the development, the authors identified the necessary hardware and software for the WRITE and outlined a schematic to show the connection of major hardware components. The third step was to develop the LWSM Model for monitoring the on-site construction labor working status by comparing data from the WRITE with the industry benchmark data. A survey methodology was used to acquire industry benchmark data from bridge construction experts. The fourth step was to demonstrate the implementation of the LWSM Model at a bridge construction site. During this phase, labor working status data collected using the WRITE was compared with the benchmark data to form the basis for the project managers and engineers to make efficiency improvement decisions. Finally, research findings and recommendations for future research were outlined. The success of this research made several contributions to the advancement of bridge construction. First, it advances the application of wireless technology in construction management. Second, it provides an advanced technology for project managers and engineers to share labor working status information among project participants. Finally, using the developed technology, project managers and engineers can quickly identify labor efficiency problems and take action to address these problems. .

Streszczenie:

When running OLTP workloads, relational DBMSs with flash SSDs still suffer from the durability overhead. Heavy writes to SSD not only limit the performance but also shorten the storage lifespan. To mitigate the durability overhead, this paper proposes a new database architecture, NV-SQL. NV-SQL aims at absorbing a large fraction of writes written from DRAM to SSD by introducing NVDIMM into the memory hierarchy as a durable write cache. On the new architecture, NV-SQL makes two technical contributions. First, it proposes the re-update interval-based admission policy that determines which write-hot pages qualify for being cached in NVDIMM. It is novel in that the page hotness is based solely on pages' LSN. Second, this study finds that NVDIMM-resident pages can violate the page action consistency upon crash and proposes how to detect inconsistent pages using per-page in-update flag and how to rectify them using the redo log. NV-SQL demonstrates how the ARIES-like logging and recovery techniques can be elegantly extended to support the caching and recovery for NVDIMM data. Additionally, by placing write-intensive redo buffer and DWB in NVDIMM, NV-SQL eliminates the log-force-at-commit and WAL protocols and further halves the writes to the storage. Our NV-SQL prototype running with a real NVDIMM device outperforms the same-priced vanilla MySQL with larger DRAM by several folds in terms of transaction throughput for write-intensive OLTP benchmarks. This confirms that NV-SQL is a cost-performance efficient solution to the durability problem.
