[MPICH] question about specifying the path in mpiexec

[Yu-Cheng Chou]

Hi,
If I have two machines (Windows and Linux), and launch an MPI program from 
the Windows machine, I can only successfully run the MPI program by using 
mpiexec -host Windows_host_name -n 1 c:\path\to\app\cpi.exe : -host
Linux_host_name -n 1 /path/to/linux/app/cpi.

But if I launch the program from the Linux machine, I can use a simpler 
way, such as 
mpiexec -path "c:\path\to\app;/path/to/app" -n 2 -machinefile file cpi

Is this a bug that keeps users from using the simpler command line in the 
first case?

Thanks
