In the last decade, machine-learning-based compilation has moved from an obscure
research niche to a mainstream activity. In this paper, we describe the relationship between …

It is often assumed that to maximize the performance of a multithreaded application, the
number of threads created should equal the number of cores. While this may be true for …

Because of the interference in the shared cache on multicore processors, the performance of
a program can be severely affected by its co-running programs. If job scheduling does not …

A design for an implemented, prototype wearable artificial sensory system is presented,
which uses data sonification to compensate for normal limitations in the human visual …

Parallel programming has transcended from HPC into mainstream, enabled by a growing
number of programming models, languages and methodologies, as well as the availability of …

Multicore multiprocessors use a Non Uniform Memory Architecture (NUMA) to improve their
scalability. However, NUMA introduces performance penalties due to remote memory …

Non-Uniform Memory Access (NUMA) architectures are ubiquitous in HPC systems. NUMA
along with other factors including socket layout, data placement, and memory contention …

We employ sparse grid regression to predict the run time in three types of numerical
simulation: molecular dynamics (MD), weather and climate simulation. The impact of …

Companies seek technological alternatives that provide competitiveness for their business
processes. One of them is integration platforms, software tools that build integration …

Diminishing performance returns and increasing power consumption of single-threaded
processors have made chip multiprocessors (CMPs) an industry imperative. Unfortunately …
