comment:1 Changed 9 years ago by mafoipsl

Partially done with [2360]. Number of OpenMP threads must be identical for all executables. For IPSLCM6-VLR we strongly suggest to run with 2 OpenMP, 25 MPI for LMDZ, 6 MPI for NEMO and 1 MPI for XIO server.

Work still required to use all cores. Work postponed until Intel MPI installation on ada.

  • Owner changed from mafoipsl to aclsce

Work done and included in libIGCM_v2.8. See :

to use it (on ada exclusively).

comment:3 Changed 7 years ago by mafoipsl
