[mpich-discuss] How to send SIGINT to each process

[Jayesh Krishna]

Hi,
 I am not sure if there is an easy way to do the cleanup. If there are
DLLs loaded by the MPI processes the entry point functions of the DLLs
should get called with "DLL_PROCESS_DETACH".
 You could change the design of your program by creating a thread to wait
for input from the user and terminate job accordingly (This would be
portable too).
 
Regards,
Jayesh

Hi Jayesh,

My program is designed to run continuously until it gets SIGINT. On
getting ctrl+C, it does some stuffs and then exits. 
Now the onus is, mpiexec just kills the process and my program does not
end gracefully. So I need this signal to be passed to each process.

Thanks,
Abhishek

Hi,
 AFAIK, smpd does not provide a way to send signals like mpd.
 Why do you want to send signals to MPI processes ?

Thanks for quick response. 

Forgot to mention last time, I need to pass SIGINT to each process on
window/vista

 I am launching the job with

mpiexec.exe -configfile <configfile>.

and on each client, smpd.exe is installed.

Thanks,
Abhishek

If you're using mpd as the job launcher, you should be able to use
mpdsigjob.
