Abstract Talk (14:00-15:00)
The European Processor Initiative (EPI) is a project aiming to develop a general-purpose processor and an accelerator as well as the software layers needed for their adoption by the HPC community. The Barcelona Supercomputing Center is promoting and participating in developing of the RISC-V-based accelerator targeting HPC. The first part of the seminar will provide an overview of the EPI project with particular attention to the co-design effort performed with Software Development Vehicles (SDV) while developing the EPI accelerator leveraging the RISC-V vector extension. The second part will be dedicated to a demo/hands-on experience on the RISC-V platforms hosted at BSC: test accounts will be provided to the attendees and participants are invited to bring their scientific codes to test.
Slides and Video
A limited amount of participants (maximum 15 different codes) can bring a code and test it via remote access on the RISC-V software development vehicle (SDV). Participants must be on-site at JSC and have to register beforehand.
Constraints: you need an app (mini-app, kernel or scientific code) that can run stand-alone on a single core with potential for vectorization.
Some hints on the code that could make the hands-on more productive:
- Application written in C/C++ or FORTRAN language
- Possibility to run a use case of the application as a sequential program
- We will not focus on MPI/OpenMP, but we could provide some support
- No strong dependencies with CUDA/OpenACC
- Avoid "complex" dependencies (to avoid having to recompile tons of libraries)
- Avoid heavy I/O traffic
