PE4.1-I Tuning without Building a Parallel Program

Background

Aim

Outcomes

  • select appropriate tasks sizes (big vs. small) that may have positive performance impacts on the workflow, and to run several (smaller) tasks by the help of job chaining
  • use mapping of processes to nodes, pinning of processes/threads to CPUs or cores, and setting memory affinities to NUMA nodes in order to speed up a parallel program
  • speed up program execution by setting appropriate runtime options (e.g. for MPI and OpenMP)
