Performance evaluation of the hybrid interactive placement with HIPPO of SCRIP interpolation tasks
Résumé
A library that controls of MPI process placement and OpenMP thread affinity at run-time (HIPPO) is introduced in OASIS and used to perform SCRIP interpolation with the most efficient decomposition, without using environment variable and allowing a different parallelism in the rest of model computations. Our tests shows that performances are preserved and that differentiated parallel layouts are correctly set from SCRIP and further calculations like the NEMO ocean model in its BENCH configuration. Preliminary results suggests that the NEMO code itself could benefit of different parallel layouts.
