That's not possible, unless there are other options you are passing to configure that you didn't mention here. With mpich-3.0.4, --with-pm=hydra is default. So whether you pass it or not, there's no difference in the build. -- Pavan On Sep 5, 2013, at 8:14 PM, Seungbum Koo wrote:

Yes the build failed without "--with-pm=hydra". I reconfigured "--with-pm=hydra" and then it worked.

I'm struggling with other issue though...

Sorry. The log file at the stage of the problem is overwritten when I was reconfiguring MPICH again.

I don't know if it will help, but I attached 'config.log' I just ran without "--with-pm=hydra" option.

Wow. Thank you for the fast replies. You guys hardly sleep.

PROBLEM SOLVED. It works now.

Nicolás/ No. that can't be. It is my personal computer and I haven't installed MPICH so far. Jeff/ I saw that FAQ but didn't try --with-pm=hydra.

I first didn't configure MPICH with any process manager since hydra is set to default according to the installation guide. I reconfigured "--with-pm=hydra" and reinstalled. Now it is working.

Once again, thank you for your interest and help.

Hi Seungbum,

No. You shouldn't need to run mpd at all.

From the FAQ: "The mpd process manager has many problems, as well as an annoying mpdboot step that is fragile and difficult to use correctly. The mpd process manager is deprecated at this point ..."

Perhaps when you typed "mpiexec", you were not really running the mpiexec binary that you had just built, but rather some other (really old) version that was already lying around on your system?

I'd suggest: running "which mpiexec" and "mpiexec --version" checking your $PATH specifying an absolute pathname to the new mpiexec binary instead of just "mpiexec"

Hope this helps, Nicolás _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
