Hello I've a problem with a parallel execution of my personal mpi program.
When I execute it on localhost it works fine, but when I try to run it with two machines I receive this error: pietro@pietro-laptop:~/Scrivania$ mpirun -- prefix /home/user/MPI/ -np 4 --host u...@xxx.yyy.zzz.kkk algo1.exe a2.txt b2. txt u...@xxx.yyy.zzz.kkk's password: [user:04778] *** Process received signal *** [user:04778] Signal: Segmentation fault (11) [user:04778] Signal code: Address not mapped (1) [user:04778] Failing at address: (nil) [user:04778] [ 0] [0xe10410] [user:04778] [ 1] algo1.exe(main+0xb9) [0x8048c8d] [user:04778] [ 2] /lib/tls/i686/cmov/libc.so.6(__libc_start_main+0xe6) [0xba5b56] [user:04778] [ 3] algo1.exe [0x8048b41] [user:04778] *** End of error message *** -------------------------------------------------------------------------- mpirun noticed that process rank 0 with PID 4778 on node u...@xxx.yyy.zzz.kkk exited on signal 11 (Segmentation fault). -------------------------------------------------------------------------- where: -> xxx.yyy.zzz.kkk is the IP of the other machine. -> /home/user/MPI/ is the installation path of MPI 1.3 of the other machine I hope that someone can give me a some advices to solve this problem. Thanks for your time
