Heterogeneous Programming on GPUs with MPI + OmpSs @ BSC

May 10, 2017, 9:00 AM → May 11, 2017, 6:00 PM CET

Room VS208, Vertex Building (Barcelona BSC Campus Nord)

The registration to this course will open in January. Please, bring your own laptop.  All the PATC courses at BSC are free of charge.

Course convener: Xavier Martorell

Objectives: The tutorial will motivate the audience on the need for portable, efficient programming models that put less pressure on program developers while still getting good performance for clusters and clusters with GPUs.

More specifically, the tutorial will:

• Introduce the hybrid MPI/OmpSs parallel programming model for future exascale systems
• Demonstrate how to use MPI/OmpSs to incrementally parallelize/optimize:
  • MPI applications on clusters of SMPs, and
  • Leverage CUDA kernels with OmpSs on clusters of GPUs

Level:

INTERMEDIATE: for trainees with some theoretical and practical knowledge; those who finished the beginners course

ADVANCED: for trainees able to work independently and requiring guidance for solving complex problems

Requirements: 

Good knowledge of C/C++

Basic knowledge of CUDA/OpenCL

Basic knowledge of Paraver/Extrae
