MPI运行时显示[proxy:0:0@localhost.localdomain] HYDU_create_process

MPI运行时显示[proxy:0:0@localhost.localdomain] HYDU_create_process解决办法总结:

    刚刚在自己的虚拟机上安装好了MPICH,准备运行一下example里面的Hellow.c,

先用mpicc -o hellow hellow.c编译,没有报错

再用mpirun -np 4 hellow 和mpiexec -np 4 hellow都出现这样的错误

[proxy:0:0@localhost.localdomain] HYDU_create_process (./utils/launch/launch.c:75): execvp error on file hellow.c (No such file or directory)

    初步解决办法

(1)、先编译: mpicc -o hellow hellow.c

(2)、在hellow的当前目录下运行:

            mpiexec -np 4 ./hellow

     或者mpirun -np 4 ./hellow
