[MPICH] Can I use mpiexec to launch different command prompts for different ranks? - Try starting manually

[Jayesh Krishna]

Hi,
 One way to do it is to set the PMI environment variables (see the
"Debugging jobs by starting them manually" section in the window's
developer's guide -- available at http://www-unix.mcs.anl.gov/mpi/mpich/)
and executing the programs manually on two windows/command prompts. 

###############2 proc job#########################
1) Start two command prompts -- run setmpi2.bat (see window's developer's
guide) on the two windows as follows
   On 1st window -- setmpi2.bat 0 2
   On 2nd window -- setmpi2.bat 1 2
2) Run your program manually on each window (Note that you do not use
mpiexec to launch the program -- all the info is provided by setmpi2.bat)
   On 1st window -- testprogram.exe
   On 2nd window -- testprogram.exe
##################################################

 Let us know if this works for you.

Regards,
Jayesh

Hi,

I have two very simple MPI programs, each of which basically asks the user
to input a number, waits for the other program to finish, and then print the
number out.

How can I use mpiexec to have two command prompts popping up for these two
programs so that they can receive standard input?

Thanks
