A Study of Disk Performance Optimization.
… by the performance of the input/output (I/O) subsystem. Other than the end user and some external peripherals, the slowest component of the I/O subsystem is the disk drive.</p> <p>One standard strategy for improving I/O subsystem performance uses high-performance hardware like Small Computer …

Parallel input/output architectures for multiprocessors
… in other parts of the system, mainly the I/O subsystem. This could lead to a huge imbalance in the system and, if not corrected, the gains made in the processing power will be of little use as the problem solving speed will be determined by the slower I/O operations.

Simulation-Aided Performance Evaluation of Input/Output Optimizations for Distributed Systems
… of operations in parallel, because the I/O subsystem can be easily overwhelmed by the sheer amount of incoming I/O operations. This, in turn, can slow down the whole distributed system. Many optimizations exist that try to alleviate this problem. Client-side optimizations do preprocessing to …

An Application-Attuned Framework for Optimizing HPC Storage Systems
… is a crucial need for revisiting the HPC I/O subsystem to better optimize for and manage the increased pressure on the underlying storage systems from big data processing. Extant HPC storage systems are designed and tuned for a specific set of applications targeting a range of workload …

Measuring, modeling, and optimizing counterintuitive performance phenomena in power-scalable, parallel systems
… insight into the inner workings of the Linux I/O subsystem, I overcome the aforementioned challenges of variance, complexity, and nondeterminism and identify the I/O resource contention as the root cause of the slowdowns during processor speedup. Specifically, such contention comes from the Linux …

Towards Automatic Load Balancing of a Parallel File System with Subfile Based Migration
… and congestion of network as well as of the I/O subsystem to ensure maximum concurrency and thus efficiency. Load balancing is a technique which tackles this issues. While load balancing has been evaluated in detail for computational parts of a program, analysis of load imbalance for complex …

Coherencia de Cache en Sistemas de Ficheros para Entornos Distribuidos y Paralelos
… in processors, memories and communication subsystems, has led the I/O subsystems to become a bottleneck in many computer systems. This problem, defined as the I/O crisis, has been mainly addressed using parallelism and caching in the I/O subsystem. Caching improves I/O performance, both for …
