Hi,
the default memheap size is 256MB, you can override it with oshrun -x
SHMEM_SYMMETRIC_HEAP_SIZE=512M ...

Hello!
Why does shmalloc return NULL when I try to allocate 512MB.
When i thry to allocate 256mb - all fine.
I useĀ Open MPI/SHMEM v1.8.4 rc1 (v1.8.3-202-gb568b6e).
programm:
#include
#include
int main(int argc, char **argv)
{
int *src;
start_pes(0);
int length = 1024*1024*512;
src = (int*) shma
