Error while running openfoam on CRAY XE6
Hello ,
I have been trying to run a big case of app 33 million cells on a CRAY XE6 machine using the script: #!/bin/bash #PBS -N Q04_large_bcchanged_final #PBS -l mppwidth=64 #PBS -l mppnppn=16 #PBS -l walltime=3:00:00 #PBS -V # Change to the direcotry that the job was submitted from cd $PBS_O_WORKDIR aprun -n 64 -N 16 interFoam -parallel > log exit But i always get an error message: [nid00073:09463] opal_os_dirpath_create: Error: Unable to create the sub-directory (/tmp/openmpi-sessions-itlkann@nid00073_0) of (/tmp/openmpi-sessions-itlkann@nid00073_0/31169/0/0), mkdir failed [1] [nid00073:09465] opal_os_dirpath_create: Error: Unable to create the sub-directory (/tmp/openmpi-sessions-itlkann@nid00073_0) of (/tmp/openmpi-sessions-itlkann@nid00073_0/31183/0/0), mkdir failed [1] [nid00073:09463] [[31169,0],0] ORTE_ERROR_LOG: Error in file util/session_dir.c at line 101 looks like I don't have permissions to generate a directory in /tmp. But i checked the permissions and: drwxrwxrwt 9 root root 16120 2011-04-15 15:40 tmp i am not sure why this problem is caused, because I actually compiled openfoam on a different front end on a different cluster, but my files are also accessible from the CRAY front end,probably because they are mounted here. Any suggestions on how to eliminate this error would be helpful. regards K.Suresh kumar |
