[mpich-discuss] using mpiexec as a dll

[Jayesh Krishna]

Hi,
 You should be able to run an MPI process as a singleton process (without mpiexec). Try running your program from the command prompt without mpiexec and let us know if you have any issues.

(PS: The singleton process should also be able to spawn MPI processes.)
Regards,
Jayesh

Subject: [mpich-discuss] using mpiexec as a dll


All, 
I have to integrate my code which requires MPICH2 - into an existing project as a dll. Ideally I would not want to spawn a child process for my code. In other words I do not want my code's dll to run mpiexec.exe as a background or child process. Is there a way to execute a MPI program without having to invoke mpiexec.exe? (I'm running MPICH2 on Windows XP) 
Thanks 
Prashanth
