ARMCI_DEFAULT_SHMMAX
This is something we are addressing for our next release. If you are experienced enough to play with c-code, the hard maximum is set in

src/tools/armci/src/memory/shmem.c around line 326

Do make sure that your system can handle large shared memory segments.

$ sysctl kernel.shmmax
kernel.shmmax = 4294967296 - this should be larger then ARMCI_DEFAULT_SHMMAX
