This usually means that there are not enough resources available to the SYSV shared memory subsystem on your server. Your OpenSHMEM job will now abort. Server: %s Requested shared memory segment size: %u Specific error: %s (%d) You can try the following: 1. Use a different sshmem plugin (e.g., "mmap") with "--mca sshmem mmap". 2. Decrease the symmetric heap area size with "-x SHMEM_SYMMETRIC_HEAP_SIZE=". 3. Increase your system's allowable SYSV shared memory segment size (e.g., via the SHMMAX and/or SMMAX kernel parameters).
