I am running mpi program on Cray XC40 system with Aries network
(using gni provider). The mpi library I use is the newest MPICH,
libfabric version is 1.6.1.
Now I test program with one node and one process. When mpi program tries to
initialize endpoint, GNI_CdmAttach function returns GNI_RC_INVALID_PARAM.
The attachment is the log it outputs, could anyone please give me some
hints that why this error happened? Thank you!
