Dear G.Vinodh Kumar,
I read your problem form internet.
hi,
i setup a two node cluster with mpich2-1.0.
the name of the master node is aarya
the name of the slave node is desktop2
i enabled the passwordless ssh session.
in the mpd.hosts, i included the name of both nodes.
the command, mpdboot -n 2 works fine.
the command, mpdtrace gives the name of both machines.
i copied the example program cpi on /home/vinodh/ on
both the nodes.
mpiexec -n 2 cpi gives the output,
Process 0 of 2 is on aarya
Process 1 of 2 is on desktop2
aborting job:
Fatal error in MPI_Bcast: Other MPI error, error
stack:
MPI_Bcast(821): MPI_Bcast(buf=0xbfffbf28, count=1,
MPI_INT, root=0, MPI_COMM_WORLD) failed

MPIC_Wait(308):

rank 0 in job 1 aarya_40878 caused collective abort
of all ranks
exit status of rank 0: return code 13
but, the other example hellow works fine.
let me know, why theres an error for the program cpi.
Regards,
G. Vinodh Kumar
At present, I have the same problem when I install Mpich2.1.0.7.
I think that you have solved this problem. Could you please instruct me how to
solve this problem?
I look forward to your reply.
Thank you first.
Sincerely,
DUong Dinh Loc.
