Subject: [OMPI users] v1.3: mca_common_sm_mmap_init error
From: Prentice Bisbal (prentice_at_[hidden])

I just installed OpenMPI 1.3 with tight integration for SGE. Version
1.2.8 was working just fine for several months in the same arrangement.

Now that I've upgraded to 1.3, I get the following errors in my standard
error file:

mca_common_sm_mmap_init: open /tmp/968.1.all.q/openmpi-sessions-prent
ice_at_node09.aurora_0/21400/1/shared_mem_pool.node09.aurora failed with
errno=2

errno=2

I've tested 3-4 different times, and the number of hosts that produces
this error varies, as well as which hosts produce this error. My program
seems to run fun, but it's just a simple "Hello, World!" program. Any
ideas? Is this a bug in 1.3?
