Modern high-speed interconnection networks are designed with capabilities to support
communication from multiple processor cores. The MPI endpoints extension has been …

The recent trend of increasing numbers of cores per chip has resulted in vast amounts of on-
node parallelism. These high core counts result in hardware variability that introduces …

Heterogeneous supercomputers are widespread over HPC systems and programming
efficient applications on these architectures is a challenge. Task-based programming …

Due to computer architecture evolution, more and more HPC applications have to include
thread-based parallelism and take care of memory consumption. Such evolutions require …

Abstract The field of High-Performance Computing is rapidly evolving, driven by the race for
computing power and the emergence of new architectures. Despite these changes, the …

A portfolio SAT solver has to share clauses in order to be efficient. In a distributed
environment, such sharing implies additional problems: more information has to be …

The advent of many-core architectures poses new challenges to the MPI programming
model which has been designed for distributed memory message passing. It is now clear …

With the advent of the multicore era, the architecture of supercomputers in HPC (High-
Performance Computing) is evolving to integrate larger computational nodes with an …

This paper deals with High Performance Computing (HPC) applied to neutron transport
theory on complex geometries, thanks to both an Adaptive Mesh Refinement (AMR) …

By allowing computation/communication overlap, MPI nonblocking collectives (NBC) are
supposed to improve application scalability and performance. However, it is known that to …
