hello, I am using openFoam-1.6 and trying to run simpleFoam with MPIRUN in a core2quad. The case is a 3d windtunnel and it has about 5300000 elements. I get the next error message:
fran@francisco-casa:~/OpenFOAM/fran-1.6/run/trompaQueAnda090929$ mpirun -np 4 simpleFoam -parallel Starting time loop Time = 1 DILUPBiCG: Solving for Ux, Initial residual = 1, Final residual = 0.0399814, No Iterations 2 DILUPBiCG: Solving for Uy, Initial residual = 1, Final residual = 0.0472701, No Iterations 2 DILUPBiCG: Solving for Uz, Initial residual = 1, Final residual = 0.0728597, No Iterations 2 DICPCG: Solving for p, Initial residual = 1, Final residual = 0.00982767, No Iterations 626 DICPCG: Solving for p, Initial residual = 0.443937, Final residual = 0.00414043, No Iterations 10 DICPCG: Solving for p, Initial residual = 0.0465286, Final residual = 0.00044602, No Iterations 49 DICPCG: Solving for p, Initial residual = 0.00843051, Final residual = 8.36603e-05, No Iterations 155 DICPCG: Solving for p, Initial residual = 0.0024325, Final residual = 2.39393e-05, No Iterations 194 time step continuity errors : sum local = 1.32836e-05, global = 6.35683e-07, cumulative = 6.35683e-07 DILUPBiCG: Solving for epsilon, Initial residual = 1, Final residual = 0.000792998, No Iterations 1 DILUPBiCG: Solving for k, Initial residual = 1, Final residual = 0.0099904, No Iterations 1 ExecutionTime = 707.49 s ClockTime = 731 s Time = 2 -------------------------------------------------------------------------- mpirun noticed that process rank 0 with PID 4274 on node francisco-casa exited on signal 9 (Killed). -------------------------------------------------------------------------- fran@francisco-casa:~/OpenFOAM/fran-1.6/run/trompaQueAnda090929$ MPIRUN just fails. It looks like there's no problem with the case, mesh, or BC. Yesterday I ran another case with MPIRUN and it worked. I use openFoam 64bits on Ubuntu-9.04 64 bits Last edited by lfbarcelo; October 2, 2009 at 17:00. |

Nobody answered, but I figured out that this error happens when you run out of RAM. The process just dies.

Either in case of out of hard drive space....
MPIRUN doesn't throw any exception for those problems as far as I know. |
