Hi!
I have recently converted two computers to Ubuntu and installed openFOAM 1.4.1 on ecah of them. I can run parallel on each node(2 cpus) but get following message when trying to run host/slave using 4cpus for a case: Executing: /home/a403518/OpenFOAM/OpenFOAM-1.4.1/.bashrc Executing: /home/a403518/OpenFOAM/OpenFOAM-1.4.1/.OpenFOAM-1.4.1/apps/ensightFoam/bashrc Executing: /home/a403518/OpenFOAM/OpenFOAM-1.4.1/.OpenFOAM-1.4.1/apps/paraview/bashrc a403518@ENEPCST75:~$ mpirun --hostfile machines simpleFoam $HOME VAFAB -parallela403518@enepcst84.af.se's password: [ENEPCST75:11188] [0,0,0] ORTE_ERROR_LOG: Data unpack had inadequate space in file dss/dss_unpack.c at line 90 [ENEPCST75:11188] [0,0,0] ORTE_ERROR_LOG: Data unpack had inadequate space in file gpr_replica_cmd_processor.c at line 361 [ENEPCST75:11188] [0,0,0] ORTE_ERROR_LOG: Data unpack had inadequate space in file dss/dss_unpack.c at line 90 [ENEPCST75:11188] [0,0,0] ORTE_ERROR_LOG: Data unpack had inadequate space in file gpr_replica_cmd_processor.c at line 361 [ENEPCST75:11188] [0,0,0] ORTE_ERROR_LOG: Data unpack had inadequate space in file dss/dss_unpack.c at line 90 [ENEPCST75:11188] [0,0,0] ORTE_ERROR_LOG: Data unpack had inadequate space in file gpr_replica_cmd_processor.c at line 361 It seem that the host finds the slave and I enter the password for the slave, then this message follows... Do I need the specific case to be copied to both nodes and do I need to start OpenFOAM on the slave before executing the mpirun command. Please help me!! //Christofer |
