[MPICH] Can I use mpiexec to launch different command prompts for different ranks? - Read input from a file

[Jayesh Krishna]

Hi,
 You can write a program to pop up a GUI which accepts the user's input.
Once the process manager is run manually (1. Stop the running process
manager -- "smpd -stop" 2. Run the process manager in a command window --
"smpd -d"  3. Repeat 1 & 2 for both the machines) the user will be able to
interact with the GUI on both the machines.
 Another way to tackle your problem is to modify your program to read the
inputs from a file (the programs would execute on the different machines and
can access different files containing the different inputs)

Regards,
Jayesh

Hi,
  These two programs are in two different Windows machines. Is there still a
way to bring up two command prompts on the host machine for user input?

Thanks!
