Hello Xen-o-Enthusiasts,
I am trying to use MPICH2-1.0.5 on Xen-3.0.3 dom-Us that
have been fired using FC-5 images. Now, I will try to explain a bit about my
setup. I have 3 domUs
192.168.37.50 : vcl050
192.168.37.51 : vcn051
192.168.37.52 : vcn052
All domUs have exactly same images. I have built and
installed mpich2-1.0.5 on FC-5 and installed it in a shared directory
(accessible by all DOM-Us). I installed it by logging as bhatia@xxxxxxxxxxxxx
(and not root). Now, when I start mpd on 192.168.37.50 like this:
bhatia@xxxxxxxxxxxxx:> mpd –daemon
bhatia@xxxxxxxxxxxxx:>
mpdtrace
192
bhatia@xxxxxxxxxxxxx:> mpiexec -np 1 /bin/hostname
192.168.37.50
So, everything works fine up till now. Now the problem is
that when I try to follow the same steps on a different DOM-U (i.e. vcn051), I
get the following:
bhatia@xxxxxxxxxxxxx:> mpd --daemon
bhatia@xxxxxxxxxxxxx:> mpdtrace
mpdtrace (mpdtrace 57): got eof on console
bhatia@xxxxxxxxxxxxx:> mpdtrace
mpdtrace (mpdtrace 57): got eof on console
bhatia@xxxxxxxxxxxxx:> mpdtrace
bhatia@xxxxxxxxxxxxx:> mpdtrace
192
--------------------------à eventually mpd
gets started successfully
bhatia@xxxxxxxxxxxxx:> mpiexec -np 1 /bin/hostname
mpiexec_192.168.37.51 (mpiexec 375): no msg recvd from mpd
when expecting ack of
request
-------------------------------------à BREAKS here
Same is the story with another DOM-U (i.e. vcn052) where I
try to start mpd as root:
[root@192 ~]# mpd --daemon
[root@192 ~]# mpdtrace
mpdtrace (mpdtrace 57): got eof on console
[root@192 ~]# mpdtrace
[root@192 ~]# mpdtrace
192
[root@192 ~]# mpiexec -np 1 /bin/hostname
mpiexec_192.168.37.52 (mpiexec 365): no msg recvd from mpd
when expecting ack of request
Can you see the problem here? Did any of you also face
similar problems?
Thanks,
Nikhil
