#704: Carpet complains about lack of mpi after ExternalLibraries/OpenMPI is built ----------------------+----------------------------------------------------- Reporter: bmundim | Owner: Type: defect | Status: new Priority: major | Milestone: Component: Cactus | Version: Resolution: | Keywords: ----------------------+-----------------------------------------------------
Comment (by eschnett):
OpenMPI cannot be used as is; several other modifications are necessary as well. These depend on some enhancements that are awaiting review, in particular #686, which in turn depends on #685.
Once these are in Cactus, one has to add "REQUIRES OpenMPI" and/or "OPTIONAL OpenMPI" statements to the configuration.ccl files of all thorns that use MPI. Also, the thorn list and many Simfactory option files need to be updated then.
