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@node09.aurora_0/21400/1/shared_mem_pool.node09.aurora failed with errno=2 [node23.aurora:20601] mca_common_sm_mmap_init: open /tmp/968.1.all.q/openmpi-sessions-prent ice@node23.aurora_0/21400/1/shared_mem_pool.node23.aurora failed with errno=2 [node46.aurora:12118] mca_common_sm_mmap_init: open /tmp/968.1.all.q/openmpi-sessions-prent ice@node46.aurora_0/21400/1/shared_mem_pool.node46.aurora failed with errno=2 [node15.aurora:12421] mca_common_sm_mmap_init: open /tmp/968.1.all.q/openmpi-sessions-prent ice@node15.aurora_0/21400/1/shared_mem_pool.node15.aurora failed with errno=2 [node20.aurora:12534] mca_common_sm_mmap_init: open /tmp/968.1.all.q/openmpi-sessions-prent ice@node20.aurora_0/21400/1/shared_mem_pool.node20.aurora failed with errno=2 [node16.aurora:12573] mca_common_sm_mmap_init: open /tmp/968.1.all.q/openmpi-sessions-prent ice@node16.aurora_0/21400/1/shared_mem_pool.node16.aurora failed with 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? -- Prentice -- Prentice Bisbal Linux Software Support Specialist/System Administrator School of Natural Sciences Institute for Advanced Study Princeton, NJ
