GROMACS version: 2020.5
GROMACS modification: No
Despite configuring with OpenMPI 4.0.5, which has HWLOC:
MCA hwloc: hwloc201 (MCA v2.1.0, API v2.0.0, Component v4.0.5)
GROMACS does not find HWLOC:
– Looking for HWLOC
– Looking for hwloc – hwloc.h not found
– Looking for hwloc – lib hwloc not found
– Could NOT find HWLOC (missing: HWLOC_LIBRARIES HWLOC_INCLUDE_DIRS) (Required is at least version “1.5”)
Does this matter in any way?
I also configured with HWLOC_DIR set to my own build of HWLOC, which eliminated the complaint; but it seems redundant to have two instances of HWLOC for the same build.
