Hi Bert,
I suspected as much. After reading some of the other posts, I started experimenting with the memory settings. The machine I intend the jobs to run on have up to 120GB of memory per node, with 32 cores per node. As I understand, the memory setting sets the memory per core, that would be in total 3.75GB/core. Even with the default 25/25/50 heap/stack/global partitioning, that are 1.875GB/core global memory.
The problem then appears to be setting the ARMCI_DEFAULT_SHMMAX. That would be 32x1.875GB = 60000, but I understand that the current limit is 8129. Is there any way to increase that or am I having things wrong?
Thanks again,
Bob
