Task-based runtimes have emerged in the HPC world to take benefit from the computation
power of heterogeneous supercomputers and to achieve scalability. One of the main …

The multidimensional scaling (MDS) is an important and robust algorithm for representing
individual cases of a dataset out of their respective dissimilarities. However, heuristics …

Task-based parallelism has adequately addressed the coding complexity required to fully
exploit the processing power offered by omnipresent hybrid CPU/GPU supercomputers …

The current trend in clusters leads towards an increase of the number of cores per node. As
a result, an increasing number of parallel applications is mixing message passing and …

Parallel runtime systems such as MPI or task-based libraries provide models to manage
both computation and communication by allocating cores, scheduling threads, executing …

New kinds of applications with lots of threads or irregular communication patterns which rely
a lot on point-to-point MPI communications have emerged. It stresses the MPI library with …

A new Design-for-Test (DfT) structure based on a configurable operational amplifier, referred
to as a" swap amp" is presented that allows access to embedded analogue blocks. The …

MPI applications may waste thousands of CPU cycles if they do not efficiently overlap
communications and computation. In this paper, we present a generic and portable I/O …

Although processors become massively multicore and therefore new programming models
mix message passing and multi-threading, the effects of threads on communication libraries …

Since the advent of multi-core processors, the physionomy of typical clusters has
dramatically evolved. This new massively multi-core era is a major change in architecture …
