With the advent of edge devices and artificial intelligence, the data deluge is a reality, making energy-efficient computing systems a must-have. Unfortunately, classical von Neumann architectures suffer from the high cost of data transfers between memories and processing units. At the same time, CMOS scaling seems more and more challenging and costly to afford, limiting the chips' performance due to power consumption issues.In this context, bringing the computation directly inside or near memories (I/NMC) seems an appealing solution. However, data-centric applications require an important amount of non-volatile storage, and modern Flash memories suffer from scaling issues and are not very suited for I/NMC. On the other hand, emerging memory technologies such as ReRAM present very appealing memory performances, good scalability, and interesting I/NMC features. However, they suffer from variability issues and from a degraded density integration if an access transistor per bitcell (1T1R) is used to limit the sneak-path currents. This thesis work aims to overcome these two challenges. First, the variability impact on read and I/NMC operations is assessed and new robust and low-overhead ReRAM-based boolean operations are proposed. In the context of neural networks, new ReRAM-based neuromorphic accelerators are developed and characterized, with an emphasis on good robustness against variability, good parallelism, and high energy efficiency. Second, to resolve the density integration issues, an ultra-dense 3D 1T1R ReRAM-based Cube and its architecture are proposed, which can be used as a 3D NOR memory as well as a low overhead and energy-efficient I/NMC accelerator

Current supercomputer architectures are subject to memory related issues. For instance we can observe slowdowns induced by memory management mechanisms and their implementation. In this context, we focus on the management of large memory segments for multi-core and NUMA supercomputers similar to Tera 100 and Curie. We discuss our work in three parts. We first study several paging policies (page coloring, huge pages. . . ) from multiple operating systems. We demonstrate an interference between those policies and layout decisions taken by userspace allocators. Such interactions can significantly reduce cache efficiency depending on the application, particularly on multi-core architectures. This study extends existing works by studying interactions between the operating system, the allocator and caches. Then, we discuss performance issues when large memory segments are allocated. We consider the interaction between the OS and userspace allocators. We show that we can significantly improve some application performances (up to 50%) by controlling the memory exchange rate with the OS and by taking care of memory topologies. We finally study page fault extensibility in current Linux kernel implementation. We observe a large impact due to page zeroing which is a security requirement. We propose an improvement on memory allocation semantic aimed at avoiding page zeroing. It shows a new interest for huge pages to improve paging scalability without changing too much kernel algorithms
Slavova, Tzvetomila. "Résolution triangulaire de systèmes linéaires creux de grande taille dans un contexte parallèle multifrontal et hors-mémoire." Thesis, Toulouse, INPT, 2009. http://www.theses.fr/2009INPT016H/document.
We consider the solution of very large systems of linear equations with direct multifrontal methods. In this context the size of the factors is an important limitation for the use of sparse direct solvers. We will thus assume that the factors have been written on the local disks of our target multiprocessor machine during parallel factorization. Our main focus is the study and the design of efficient approaches for the forward and backward substitution phases after a sparse multifrontal factorization. These phases involve sparse triangular solution and have often been neglected in previous works on sparse direct factorization. In many applications, however, the time for the solution can be the main bottleneck for the performance. This thesis consists of two parts. The focus of the first part is on optimizing the out-of-core performance of the solution phase. The focus of the second part is to further improve the performance by exploiting the sparsity of the right-hand side vectors. In the first part, we describe and compare two approaches to access data from the hard disk. We then show that in a parallel environment the task scheduling can strongly influence the performance. We prove that a constraint ordering of the tasks is possible; it does not introduce any deadlock and it improves the performance. Experiments on large real test problems (more than 8 million unknowns) using an out-of-core version of a sparse multifrontal code called MUMPS (MUltifrontal Massively Parallel Solver) are used to analyse the behaviour of our algorithms. In the second part, we are interested in applications with sparse multiple right-hand sides, particularly those with single nonzero entries. The motivating applications arise in electromagnetism and data assimilation. In such applications, we need either to compute the null space of a highly rank deficient matrix or to compute entries in the inverse of a matrix associated with the normal equations of linear least-squares problems. We cast both of these problems as linear systems with multiple right-hand side vectors, each containing a single nonzero entry. We describe, implement and comment on efficient algorithms to reduce the input-output cost during an outof- core execution. We show how the sparsity of the right-hand side can be exploited to limit both the number of operations and the amount of data accessed.

This thesis investigates the pivotal role of emerging non-volatile memory (NVM) technologies, with a primary focus on Resistive Random-Access Memory (ReRAM), in addressing the challenges of memory latency associated with the shrinking of logic components. The exploration begins by elucidating the fundamental physics of ReRAM and its potential applications in in-memory and neuromorphic computing.The second chapter delves into material engineering strategies to optimize ReRAM performance, covering aspects such as top electrode materials, doping effects, and the benefits of a bi-layer resistive switching (RS) oxide stack. These insights provide a foundation for subsequent investigations into device reliability.A Kinetic Monte Carlo (KMC) simulation framework is introduced in the third chapter, offering a powerful tool for probing the microscopic dynamic behavior of ReRAM. This framework becomes instrumental in the fourth chapter, where the physics of ReRAM reliability, specifically resistance fluctuations, is explored in depth. The analysis reveals intricate mechanisms governing fluctuations and their impact on metrics like the standard Failing Bit Count (FBC).In the final chapter, the application of ReRAM devices as synapses in artificial neural networks (ANNs) is revisited. Programming techniques and strategies to mitigate the impact of fluctuations, particularly in multi-level cell (MLC) ReRAM, are discussed. The thesis concludes by emphasizing the crucial role of ReRAM material stack engineering in designing reliable synapses for future computing paradigms.This comprehensive exploration contributes to advancing our understanding of ReRAM's potential, offering insights into device optimization, reliability, and its application in neuromorphic computing. Looking forward, the research underscores the significance of continued innovation in ReRAM material engineering to unlock its full capabilities and facilitate its integration into the evolving landscape of computing technologies

The energy consumption of the memory system in modern architectures is a major issue for embedded system limited by their battery or supercalculators limited by their Thermal Design Power. Using a classification information in the memory system allows a heterogeneous management of data, more specific to each kind of data. During this thesis, we focused on the specific management of read-only data into the memory system through a compilation/architecture codesign. It allows to explore new potentials in terms of data locality, scalability of the system or cache designs. Evaluated by simulation with multi-core architecture, the proposed solution others significant energy consumption reduction while keeping the performance stable

This work aims at studying the exploitation of high-speed networks of clusters for distributed storage. Parallel applications running on clusters require both high-performance communications between nodes and efficient access to the storage system. Many studies on network technologies led to the design of dedicated architectures for clusters with very fast communications between computing nodes. Efficient distributed storage in clusters have been essentially developed by adding parallelization mechanisms so that the server(s) may sustain an increased workload. In this work, we propose to improve the performance of distributed storage systems in clusters by efficiently using the underlying high-performance network to access distant storage systems. The main question we are addressing is: do high-speed networks of clusters fit the requirements of a transparent, efficient and high-performance access to remote storage? We show that storage requirements are very different from those of parallel computation. High-speed networks of clusters were designed to optimize communications between different nodes of a parallel application. We study their utilization in a very different context, storage in clusters, where client-server models are generally used to access remote storage (for instance NFS, PVFS or Lustre). Our experimental study based on the usage of the GM programming interface of Myrinet high-speed networks for distributed storage did raised several interesting problems. Firstly, the specific memory utilization in the storage access system layers does not easily fit the traditional memory model of high-speed networks. Secondly, client-server models that are used for distributed storage have specific requirements on message control and event processing, which are not handled by existing interfaces. We propose different solutions to solve communication control problems at the file-system level. We show that a modification of the network programming interface is required. Data transfer issues need an adaptation of the operating system. We detail several propositions for network programming interfaces which make their utilization easier in the context of distributed storage. The integration of a flexible processing of data transfer in the new programming interface Myrinet/MX is finally presented. Performance evaluations show that its usage in the context of both storage and other types of applications is easy and efficient
