Observations show that some HPC applications periodically alternate between (i) operations
(computations, local data accesses) executed on the compute nodes, and (ii) I/O transfers of …

Performance variability is an important measure for a reliable high performance computing
(HPC) system. Performance variability is affected by complicated interactions between …

Although high-performance computing (HPC) systems have been scaled to meet the
exponentially growing demand for scientific computing, HPC performance variability …

Performance variability management is an active research area in high-performance
computing (HPC). In this article, we focus on input/output (I/O) variability, which is a …

Recently, Egypt has recognized the pivotal role of High Performance Computing in
advancing science and innovation. Additionally, Egypt realizes the importance of …

Variability in the execution time of computing tasks can cause load imbalance in high-
performance computing (HPC) systems. When configuring system-and application-level …

Although high-performance computing (HPC) systems have been scaled to meet the

Many fields of science rely on the collection of samples and estimation of true population
distributions from those samples. There are several effective nonparametric methods for …

In high performance computing, platforms (the supercomputers) are composed of
computational resources divided into racks. Each rack have one (sometimes several) I/O …

In this thesis, two distinct problems in data-driven computational science are considered.
The main problem of interest is the multiobjective optimization problem, where the tradeoff …
