The second Exa-SofT annual assembly, held on November 7th-8th, 2024 at ENSEEIHT in Toulouse, brought together over 50 participants from academia and industry to share progress on scientific computing applications, strengthen collaborations, and introduce the new members of Exa-SofT.
Exa-SofT (HPC software and tools) is one of the five projects of the NumPEx program. It is concerned with research issues around the development of efficient, portable and scalable software for exaflop-scale supercomputers which are, by nature, of a very large size, and heterogeneous. As such, Exa-SofT deals with the development and use of parallel programming models for accelerators such as GPUs, compile and runtime optimizations, the development of low-level libraries for linear and multilinear algebra, and performance and energy analysis and optimization.
The second Exa-SofT annual assembly took place on 7th and 8th November 2024 in the facilities of the ENSEEIHT school of Toulouse. It gathered 50+ participants from all over France. Experts in scientific computing applications from the industrial and academic world also attended the meeting in a joint effort to foster collaborations. During the two days of the event, eight scientific talks were given by members of Exa-SofT to present the latest results and progress achieved in the different work-packages. Two plenary sessions were also organized to discuss about the consolidation and interoperability of the software packages developed in Exa-SofT on the one hand, and about interactions with application experts around the development of mini-apps on the other hand. One highlight of this meeting was the large participation of young Exa-SofT members (PhD students and post-docs), who had the opportunity to introduce themselves – as well their research – to the audience.
