在Ubuntu（安裝了mpich和openmpi）下MPI編程時，代碼沒問題，但是在mpirun啟動並執行時候出現如下問題
[ubuntu:04803] *** Process received signal ***[ubuntu:04803] Signal: Segmentation fault (11)[ubuntu:04803] Signal code: Address not mapped (1)[ubuntu:04803] Failing at address: 0x7548d0c[ubuntu:04803] [ 0] [0x86b410][ubuntu:04803] [ 1] /lib/tls/i686/cmov/libc.so.6(fclose+0x1a0) [0x186b00][ubuntu:04803] [ 2] ./exmpi_2(main+0x78e) [0x80492c2][ubuntu:04803] [ 3] /lib/tls/i686/cmov/libc.so.6(__libc_start_main+0xe6) [0x141bd6][ubuntu:04803] [ 4] ./exmpi_2() [0x8048aa1][ubuntu:04803] *** End of error message ***

折騰了半天，最後刪掉了openmpi

sudo apt-get remove  libopenmpi-dev openmpi-bin

   安裝mpich 

sudo apt-get install  libmpich-dev openmpi-bin

  一切搞定！！！
