[Pw_forum] Problem in parallel execution, please help

[xirainbow]

Dear dev sharma:


>(a) env MPIF90=mpif77 ./configure (after this command finally it gave mssg,
parallel >envoirnment successful)
Why not use mpif90 instead of mpif77

>piexec_localhost.localdomain: cannot connect to local mpd
>(/tmp/mpd2.console_sushil); possible causes:
 >1. no mpd is running on this host
 >2. an mpd is running but was started without a "console" (-n option)
>In case 1, you can start an mpd on this host with:

It is a problem of mpi, not QE.
Simply follow the instruction: start an mpd on your host with "mpd"

or you can try the following way:
0.down load mpich2-1.0.8.tar.gz on intelnet
1.enter directory /etc, then input "touch mpd.conf" using terminal.
2.input "vi mpd.conf"
3.add "MPD_SECRETWORD=XXXXX"   (XXXXXX is your secrete number)
4.return to terminal and input mpdboot
