Hello, I have developed a code which I tested on MPICH2, it working fine.
But when I compile and run it with OpenMPI, its not working. The result of the program with the errors by OpenMPI is below .. -------------- bibrak@barq:~/XXX> mpirun -np 4 ./exec 98 warning:regcache incompatible with malloc warning:regcache incompatible with malloc warning:regcache incompatible with malloc warning:regcache incompatible with malloc Send count -- >> 25 Send count -- >> 25 Send count -- >> 24 Send count -- >> 24 Dis -- >> 0 Dis -- >> 25 Dis -- >> 50 Dis -- >> 74 0 d[0] = -14.025975 1 d[0] = -14.025975 -- 1 -- 2 d[0] = -14.025975 -- 2 -- -- 0 -- 3 d[0] = -14.025975 --3 -- [barq:27118] *** Process received signal *** [barq:27118] Signal: Segmentation fault (11) [barq:27118] Signal code: Address not mapped (1) [barq:27118] Failing at address: 0x51681f96 [barq:27121] *** Process received signal *** [barq:27121] Signal: Segmentation fault (11) [barq:27121] Signal code: Address not mapped (1) [barq:27121] Failing at address: 0x77b5685 [barq:27118] [ 0] [0xffffe410] [barq:27118] [ 1] /lib/libc.so.6(cfree+0x9c) [0xb7d20f3c] [barq:27118] [ 2] ./exec(main+0x2214) [0x804ad8d] [barq:27118] [ 3] /lib/libc.so.6(__libc_start_main+0xe5) [0xb7cc9705] [barq:27121] [ 0] [0xffffe410] [barq:27121] [ 1] /lib/libc.so.6(cfree+0x9c) [0xb7d0ef3c] [barq:27121] [ 2] ./exec(main+0x2214) [0x804ad8d] [barq:27121] [ 3] /lib/libc.so.6(__libc_start_main+0xe5) [0xb7cb7705] [barq:27121] [ 4] ./exec [0x8048b01] [barq:27121] *** End of error message *** [barq:27118] [ 4] ./exec [0x8048b01] [barq:27118] *** End of error message *** -------------------------------------------------------------------------- mpirun noticed that process rank 3 with PID 27121 on node barq exited on signal 11 (Segmentation fault). -------------------------------------------------------------------------- [barq:27120] *** Process received signal *** [barq:27120] Signal: Segmentation fault (11) [barq:27120] Signal code: Address not mapped (1) [barq:27120] Failing at address: 0x4bd1ca3e [barq:27120] [ 0] [0xffffe410] [barq:27120] [ 1] /lib/libc.so.6(cfree+0x9c) [0xb7c97f3c] [barq:27120] [ 2] ./exec(main+0x2214) [0x804ad8d] [barq:27120] [ 3] /lib/libc.so.6(__libc_start_main+0xe5) [0xb7c40705] [barq:27120] [ 4] ./exec [0x8048b01] [barq:27120] *** End of error message *** ---------------- Because of the warning:regcache incompatible with malloc warning I did > bibrak@barq:~/XXX> export MX_RCACHE=2 And now ignored the warning, but the error still remains I shall appreciate any help.
