[mvapich-discuss] Problem with reading parameters from stdin

[Liu Jianyu]

Hi,


I have a problem with reading namelist from stdin for the MPI run if built
ARPS with mvapich2 2.0b

For example,

    mpirun -np 12 arps_mpi  < namelist.input

It  aborted with "process reading stdin too slowly" immediately.

It is required that only one processor ( the root processor with rank0)
reads the stdin for configuration parameters.  In the IBM Parallel 
Operatin Environment, there is an option "stdinmode 0" instructs 
POE to allow only the processor with rank 0 read the stdin.

Just wondering how to do this way with mvapich2 ?


Here are the output of ' mpiname -a'

./mpiname -a
