MPICH with shmem problem

[Jeff Layton]

Good morning,

  I can't remember if I posted this particular problem to this
mailing list or not. I'm using MPICH-1.2.4 that was built with
shmem (I didn't build it) and the Intel7 compilers for Linux
and the PGI v4 compilers for Linux. When I run my code
built with either compiler, I get the following error message:


p16_12049: (1.828541) xx_shmalloc: returning NULL; requested 8825548 bytes
p16_12049: (1.828597) p4_shmalloc returning NULL; request = 8825548 bytes
You can increase the amount of memory by setting the environment variable
P4_GLOBMEMSIZE (in bytes); the current size is 9000000
p16_12049:  p4_error: alloc_p4_msg failed: 0
bm_list_6703: (3.271396) wakeup_slave: unable to interrupt slave 0 pid 6702


To me this looks like I have set P4_GLOBMEMSIZE to an
appropriate size. What am I missing?


TIA,

Jeff
