Linux系统下mpi 编程出现：Signal: Segmentation fault， Signal code: Address not mapped

在Ubuntu（安装了mpich和openmpi）下MPI编程时，代码没问题，但是在mpirun运行的时候出现如下问题
[ubuntu:04803] *** Process received signal ***
[ubuntu:04803] Signal: Segmentation fault (11)
[ubuntu:04803] Signal code: Address not mapped (1)

折腾了半天，最后删掉了openmpi

sudo apt-get remove  libopenmpi-dev openmpi-bin

   安装mpich 

sudo apt-get install  libmpich-dev openmpi-bin

  一切搞定！！！
