A source-to-source compiler is a type of translator that accepts the source code of a program
written in a programming language as its input and produces an equivalent source code in …

The C/C++ compilation stack (Intermediate Representations (IR), compilation passes and
backends) is encumbered by a steep learning curve, which we believe can be lowered by …

Fault-tolerance has always been an important topic when it comes to running massively
parallel programs at scale. Statistically, hardware and software failures are expected to …

Adaptive MPI is an implementation of the MPI standard that supports the virtualization of
ranks as user‐level threads, rather than OS processes. In this work, we optimize the …

parallel programs at scale. Statistically, hardware and software failures are expected to …

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 …

The evolution of parallel computing architectures presents new challenges for developing
efficient parallelized codes. The emergence of heterogeneous systems has given rise to …

Abstract The Message Passing Interface (MPI) is the dominant programming system for
scientific applications that run on distributed memory parallel computers. MPI is a library …

Distributed software using MPI is now facing a complexity barrier. Indeed, given increasing
intra-node parallelism, combined with the use of accelerator, programs' states are becoming …

Asynchronous many-task runtimes look promising for the next generation of high
performance computing systems. But these runtimes are usually based on new …
