I am using Open MPI, I got the error:
n337:37664] *** Process received signal ***[n337:37664] Signal: Segmentation fault (11)[n337:37664] Signal code: Address not mapped (1)[n337:37664] Failing at address: 0x7fffcfe90000[n337:37664] [ 0] /lib64/libpthread.so.0 [0x3c50e0e4c0][n337:37664] [ 1] /lustre/home/rhascheduler/RhaScheduler-0.4.1.1/mytest/nmn2 [0x414ed7][n337:37664] [ 2] /lib64/libc.so.6(__libc_start_main+0xf4) [0x3c5021d974][n337:37664] [ 3] /lustre/home/rhascheduler/RhaScheduler-0.4.1.1/mytest/nmn2(__gxx_personality_v0+0x1f1) [0x412139][n337:37664] *** End of error message ***
After searching answers, it seems that some functions fail. My program can run well for 1,2,10 processors, but fail when the number of tasks cannotbe divided evenly by number of processes.
Any help is appreciated.
