<font size="3">Thanks very much for the help. Actually i could not run mpiexec -info (there was no -info option); however a colleague gave me another (rather more complicated) script to do the parallel run. Now, I get another error which is the following:</font><div><br></div><div>"<span style="font-family: 'Courier New'; font-size: 10pt; ">/var/log/slurm/slurmd/job785314/slurm_script:

Can you run<br>> "/opt/mpi/mpibull2-1.3.9-18.s/bin/mpiexec -info" to generate detailed<br>> version information on your MPICH2 installation?<br>> <br>> Regardless of the version of MPICH2 you are using, your problem has to<br>> do with MPD, but MPD is no longer supported. You can refer to<br>> http://wiki.mcs.anl.gov/mpich2/index.php/Frequently_Asked_Questions#Q:_I_don.27t_like_.3CWHATEVER.3E_about_mpd.2C_or_I.27m_having_a_problem_with_mpdboot.2C_can_you_fix_it.3F<br>> for more information.<br>> <br>> Hydra is the replacement for MPD and it is an excellent process<br>> manager. The system administrators at your site should install a more<br>> recent version of MPICH2 that will have Hydra as the default process<br>> manager. If your machine has Infiniband, recent versions of MVAPICH2<br>> (which is derived from MPICH2) will also have Hydra support.<br>> <br>> Best,<br>> <br>> Jeff<br>> <br>> <br>> On Sun, Feb 5, 2012 at 4:03 PM, Elie M <elie.moujaes@hotmail.co.uk> wrote:<br>> > Dear sir/madam,<br>> ><br>> ><br>> ><br>> > I am running a parallel execution (pw.x) on a SLURM LINUX interface and<br>> > once I run the command sbatch filename.srm, the calculation starts running<br>> > and then stops with the follwing error:<br>> ><br>> ><br>> ><br>> > "mpiexec_veredas5: cannot connect to local mpd<br>> ><br>> > (/tmp/mpd2.console_sushil); possible causes:<br>> ><br>> > 1. no mpd is running on this host<br>> ><br>> > 2. an mpd is running but was started without a "console" (-n option)<br>> ><br>> > In case 1, you can start an mpd on this host with:<br>> ><br>> > mpd &<br>> ><br>> > and you will be able to run jobs just on this host.<br>> ><br>> > For more details on starting mpds on a set of hosts, see<br>> ><br>> > the MPICH2 Installation Guide."<br>> ><br>> ><br>> > The script is executed using the package of quantum Espresso (QE).
