[MPICH2-dev] mpich2 booting problem

[Rajeev Thakur]

The MPICH2 Installer's Guide in the doc/installguide directory has some
instructions on what to do if MPD does not run, such as running mpdcheck.
Have you tried those steps?

hello,
    
    I have installed mpich2 and intel fortran compiler but when i try to do
mpdboot on sample example on more than 2 processors , I got the following
error:

$ mpdboot -n 2
mpdboot_pg_0 (mpdboot 393): error trying to start mpd(boot) at 1 {'host':
'172.27.22.184', 'ncpus': 1, 'ifhn': ''}; output:
   mpdboot_localhost_1 (err_exit 415): mpd failed to start correctly on
localhost
     reason: 1: unable to ping local mpd;
   invalid msg from mpd :{}:
   ** mpd may have disappeared, perhaps due to mismatched secretwords
   ** see msgs logged in syslog and /tmp/mpd2.logfile* on localhost
   last printed output from mpd before becoming a daemon:
   33151
   
   mpdboot_localhost_1 (err_exit 421):   contents of mpd logfile in /tmp:
        logfile for mpd with pid 8832
        localhost_33151: conn error in connect_lhs: Connection refused
        localhost_33151 (connect_lhs 542): failed to connect to lhs at pg
33166
        localhost_33151 (enter_ring 500): lhs connect failed
        localhost_33151 (run 215): failed to enter ring
mpdboot_pg_0 (err_exit 415): mpd failed to start correctly on pg

It works fine with one processor. I am using ssh without password with nfs
on two processor and it works quite fine.

Looking Forward to ur reply.
