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.

You should not have to specify hydra with the 3.0.4 release. It is the default. Can you send your config.log so we know what went wrong? ----- Original Message ----- > From: "Seungbum Koo" <doougsini(a)gmail.com> > To: "Jeff Hammond" <jeff.science(a)gmail.com>, nrosner(a)gmail.com > Cc: "MPICH" <discuss(a)mpich.org> > Sent: Thursday, September 5, 2013 6:59:12 AM > Subject: Re: [mpich-discuss] Do I need to run "mpd" every time before I execute "mpiexec"? > > > > > > Wow.

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, > do I need to run "mpd" every time before I run "mpiexec"? 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

Do I need to run "mpd" every time before I execute "mpiexec"?
by Seungbum Koo 04 Sep '13

Hello all. I installed MPICH-3.0.4 today and I think I went through without any bugging issues. (Last time it was horrible...) Problem is that when I run "cpi" to check if mpiexec is running correctly, the following message appears on the screen. =================================================================== simba@asterix:/opt/mpich/mpich-3.0.4-build/examples$ mpiexec -np 4 ./cpi mpiexec_asterix: cannot connect to local mpd (/tmp/mpd2.console_simba); possible causes: 1. no mpd is running on this host 2. an mpd is running but was started without a "console" (-n option) simba@asterix:/opt/mpich/mpich-3.0.4-build/examples$ =================================================================== So I did what the error message said and it looks like working fine. =================================================================== simba@asterix:/opt/mpich/mpich-3.0.4-build/examples$ mpd & [1] 7749 simba@asterix:/opt/mpich/mpich-3.0.4-build/examples$ mpiexec -np 4 ./cpi Process 1 of 4 is on asterix Process 2 of 4 is on asterix Process 0 of 4 is on asterix pi is approximately 3.1415926544231279, Error is 0.0000000008333347 wall clock time = 0.000070 Process 3 of 4 is on asterix simba@asterix:/opt/mpich/mpich-3.0.4-build/examples$ =================================================================== My question is, do I need to run "mpd" every time before I run "mpiexec"? Is there any wise way of going around? Seungbum
