Looks like I’m late to this email chain. Please don’t use mpd. mpd has been deprecated for many releases of mpich now. You might be using a very old version of mpich. —- Pavan On Nov 6, 2013, at 6:26 PM, bharat gupta <[email protected]> wrote:
DO I need to add some command in mpd.hosts file

" If a file named .mpd.conf is available in the user's home directory, only the user can have read and write privileges. The file must minimally contain a line with secretword=<secretword>. If you want to run MPD as root, create the mpd.conf file in the /etc directory instead of .mpd.conf in the root's home directory to run mpd as root. Avoid starting the MPD ring under the root account." Here'e the link http://software.intel.com/sites/products/documentation/hpc/ics/impi/41/lin/R...
And after using chmod 700 , I still get the same error, but when I create a file mpd.conf in /etc I get the and added the secretword=<secretword> line in the file and run the same command, I get this error:-
root@localhost INGT]# mpirun -np 24 mdrun -v -deffnm mdrun mpdroot: perror msg: No such file or directory mpdroot: cannot connect to local mpd at: /tmp/mpd2.console_root probable cause: no mpd daemon on this machine possible cause: unix socket /tmp/mpd2.console_root has been removed

I am getting the following error while using the command -
[root@localhost INGT]# mpirun -np 24 mdrun_mpi -v -deffnm npt
Error -
/usr/bin/mpdroot: open failed for root's mpd conf filempiexec_localhost.localdomain (__init__ 1208): forked process failed; status=255
I complied gromacs using - ./configure --enable-shared --enable-mpi. I have installed the mpich package , this is what I get when I check for mpirun and mpiexec -
[root@localhost /]# which mpirun /usr/bin/mpirun [root@localhost /]# which mpiexec /usr/bin/mpiexec
What could be the problem here ??
