Primary tabs


Topics: We can help on optimizing applications using a variety of programming models. We also have mentors from many disciplines, including computer scientists and domain scientists. We will make sure we have the right mentors for you in case your application is selected. Note that this is not a GPU-only hackathon.

  • Participants will have access to the resources of the general-purpose cluster of the MareNostrum 4 supercomputer and the GPU enable MN4 CTE-Power cluster and will use, among others, the technologies of the BSC Extrae, Paraver, Dimemas, OmpSs, OmpSs-2, OmpSs-2 @ OpenACC and OmpSs-2 @ Cluster.

Furthermore, in the event we will count with experts who can help teams to work on their codes. In general terms, experts can give advice on:

· Programming models: CUDA, MPI, OpenMP, OpenACC, OmpSs-2, and HIP.

· Tools: Extrae/Paraver (performance analysis), Dynamic Load Balance, Parallelware (analyzer, trainer).

· Systems dev-ops.

HPCNow!: Services and Tools for GPGPU development and maintenance

We present a concise description of some tools and services related to General Purpose Graphical Processing Units development. Architecture, development, and management are included in the roll of services and training HPCNow offers. For a science-related environment, we discuss distributed parallel libraries like MPI and NCCL, features like Multi-Instance GPU (MIG), and tools for monitoring and reporting like NVIDIA Data Center GPU Manager (DCGM).
