[mvapich-discuss] Readme mpiexec example is not working

[bright.yang at vaisala.com]

Hi,

 

  I'm running the example of the latest Mvapich217 a2 release. The
example in the readme file mpiexec -f machinefile -n <number>
./examples/cpi

 

Is not working. It got error message like this -

# mpiexec -f 2_12hosts -n 24 ./wrf.exe

-file (-f) arg must appear alone

 

Here is what's in my hostfile 2_12hosts:

compute-0-0:12

compute-0-1:12

 

Thanks!

 

Bright Yang
