Description of problem: I notice there's no support for the PSM MTL needed for "the other" Infiniband hardware from Intel (whatever it's called this year). It is provided in RHEL as the openmpi-psm package, depending on infinipath-psm. infinipath-psm isn't in Fedora, but the el6 source package builds directly on f22. Infinipath packaging would also be relevant to libfabric, but I don't know if building openmpi-1.10 against libfabric would be equivalent to the PSM MTL.
Personally, I don't have any time/interest to work on this. But if psm/psm2/whatever were packaged for Fedora, it would be trivial to enable openmpi support.
This bug appears to have been reported against 'rawhide' during the Fedora 24 development cycle. Changing version to '24'. More information and reason for this action is here: https://fedoraproject.org/wiki/Fedora_Program_Management/HouseKeeping/Fedora24#Rawhide_Rebase
FWIW, I noticed infinipath-psm is recently packaged.
libpsm2 is available in Rawhide (but not in F24). To build openmpi with PSM2 support it should be sufficient to add libpsm2-devel to BuildRequires. However, openmpi does not build in Rawhide, due to glibc finally poisoning the __malloc_initialize_hook symbol: https://sourceware.org/bugzilla/show_bug.cgi?id=19564 https://sourceware.org/git/gitweb.cgi?p=glibc.git;a=commitdiff;h=2ba3cfa1607c36613f3b30fb1ae4ec530245ce64 In file included from btl_openib_component.c:58:0: ../../../../opal/mca/memory/linux/malloc.h:233:29: error: attempt to use poisoned "__malloc_initialize_hook" OPAL_DECLSPEC extern void (*__malloc_initialize_hook) __MALLOC_PMT ((void)); ^
v1.10.3 (upstream release likely to happen today) will build against the new glibc, because ./configure added a check for "__malloc_initialize_hook", so it will disable MCA component memory:linux. https://github.com/open-mpi/ompi-release/commit/c2798a8bd6dddf68b69608ee04500261a0eda842
Built for rawhide. Hope to move to older releases in a bit.
