hello,
I am new to openfoam, and i am using the solver " icoUncoupledKinematicParcelFoam". i want to run the tutorial of hopper in parallel with 4 processors on my computer. i did not change anything of the decomposeParDic file, and the step of " decomposePar" worked well. then, when i ran " mpirun -np 4 icoUncoupledKinematicParcelFoam -parallel ", there were problems. -------------------------------------------------------------------------- Sorry! You were supposed to get help about: find-available:not-valid But I couldn't open the help file: /home/inet107/OpenFOAM/ThirdParty-2.2.2/platforms/linux64Gcc/openmpi-1.6.3/share/openmpi/help-mca-base.txt: No such file or directory. Sorry! -------------------------------------------------------------------------- [inet107-Precision-T7610:04118] *** Process received signal *** [inet107-Precision-T7610:04118] Signal: Segmentation fault (11) [inet107-Precision-T7610:04118] Signal code: Address not mapped (1) [inet107-Precision-T7610:04118] Failing at address: 0x28 [inet107-Precision-T7610:04118] [ 0] /lib/x86_64-linux-gnu/libpthread.so.0(+0xfcb0) [0x7f419805ecb0] [inet107-Precision-T7610:04118] [ 1] /usr/lib/libopen-pal.so.0(mca_base_select+0x108) [0x7f419828e518] [inet107-Precision-T7610:04118] [ 2] /usr/lib/libopen-pal.so.0(opal_crs_base_select+0x7e) [0x7f41982a090e] [inet107-Precision-T7610:04118] [ 3] /usr/lib/libopen-pal.so.0(opal_cr_init+0x31e) [0x7f419827f0ee] [inet107-Precision-T7610:04118] [ 4] /usr/lib/libopen-pal.so.0(opal_init+0x159) [0x7f419827ea59] [inet107-Precision-T7610:04118] [ 5] /usr/lib/libopen-rte.so.0(orte_init+0x4d) [0x7f41984d0a0d] [inet107-Precision-T7610:04118] [ 6] mpirun() [0x402fe5] [inet107-Precision-T7610:04118] [ 7] mpirun() [0x402b34] [inet107-Precision-T7610:04118] [ 8] /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xed) [0x7f4197cb176d] [inet107-Precision-T7610:04118] [ 9] mpirun() [0x402a59] [inet107-Precision-T7610:04118] *** End of error message *** any help will be appreciated! ! thx |

haha, i finally solved this problem.
after the installation, you should find the bashrc file in etc/. then change the "openmpi" to "SYSTEMOPENMPI" at the 82 line. |
