I found that with 1.3.4 I can run the example much longer until I hit this error message: [master] (31996) forking processes [mujo:14273] opal_os_dirpath_create: Error: Unable to create the sub-directory (/tmp/.private/nbock/openmpi-sessions-nbock@mujo_0/13386/31998) of (/tmp/.private/nbock/openmpi-sessions-nbock@mujo_0/13386/31998/0), mkdir failed [1] [mujo:14273] [[13386,31998],0] ORTE_ERROR_LOG: Error in file util/session_dir.c at line 101 [mujo:14273] [[13386,31998],0] ORTE_ERROR_LOG: Error in file util/session_dir.c at line 425 [mujo:14273] [[13386,31998],0] ORTE_ERROR_LOG: Error in file base/ess_base_std_app.c at line 132 -------------------------------------------------------------------------- It looks like orte_init failed for some reason; your parallel process is likely to abort. There are many reasons that a parallel process can fail during orte_init; some of which are due to configuration or environment problems. This failure appears to be an internal failure; here's some additional information (which may only be relevant to an Open MPI developer): orte_session_dir failed --> Returned value Error (-1) instead of ORTE_SUCCESS > On Dec 1, 2009, at 4:38 PM, Nicolas Bock wrote: > > > > On Tue, Dec 1, 2009 at 16:28, Abhishek Kulkarni <abbyzc...@gmail.com>wrote: > >> On Tue, Dec 1, 2009 at 6:15 PM, Nicolas Bock <nicolasb...@gmail.com> >> wrote: >> > After reading Anthony's question again, I am not sure now that we are >> having >> > the same problem, but we might.
