[mpich-discuss] MPICH2 Error

[Jayesh Krishna]

Hi,
 Why do you want to launch a parallel program from another parallel program ?
 You can run MPMD programs using mpiexec (mpiexec -n 3 A.exe : -n 2 B.exe). If you don't want the programs to be part of the same job why not launch two jobs ?

It is not the problem of network connectivity because I only run on a computer with 4 cores. Furthermore, the firewall has been turned down. 
I used MPIEXEC wrapper to run the main parallel program A. In program A, a command was added to call another parallel program B. This is done by command as "C:\Program Files\MPICH2\bin\mpiexec.exe" -n 3 B.exe . However, program B will not be executed. I can not understand what is wrong with mpich2. However, if I use a serial program to call parallel program B, it is executed normally.

>I found a problem when i used mpich2 in windows. First, I use mpich2 to run a parallel program A. Then, program A will call another parallel program B using mpich2 too. However, program B will not be excuted which show a error code of 10061. Below are the error informations. Could you help me fix this problem? thank you Da Xingya
