Accelerators and Communications for HPC (AccelCom)

Primary tabs

Our team drives leading-edge research and development around 3 main pillars: (1) Accelerators/coprocessors in HPC, (2) Programmability of heterogeneous memory systems, and (3) Inter-node communications. We collaborate closely with the major accelerator/coprocessor and network vendors for HPC: NVIDIA, Intel, and Mellanox. We run the BSC/UPC NVIDIA GPU Center of Excellence and collaborate with the Intel-BSC Exascale Lab. activities. We organize locally international events such as the PUMPS+AI Summer School, PATC Courses on CUDA/OpenACC and use of heterogeneous memory systems, and the MareNostrum hackathon, and collaborate in the organization of related international conferences and workshops such as HMEM or AsHES.


Our broad mission is driving top-notch research and development around accelerators and communications technology for HPC. This can be framed in three main points:

  • Helping vendors advance their hardware architecture and software stack.
  • Designing and developing programming models, runtime systems, and libraries supporting accelerated computing and networking.
  • Developing and porting coprocessor-accelerated and distributed-memory applications.
