Well, so much for the easy one :(.
Is it possible that you have two versions of Open MPI in your path
somewhere and that you might be getting different versions on
different nodes? The errors below generally indicate that data was
received in a totally different format than expected, so I'm just
kind of guessing as to how one could get to that situation...

- Both my nodes are Intel Xeons and run linux 2.4.26.

Hey Guys,
Not sure what is going on here, has anyone seen this before?

Hi Galen,
Sorry to bother you.
I have installed latest stable version of Open MPI(1.0) on two
of spider
nodes(s7,s4) for some experiments, but there seems to be
configuration
error or something else which I don't understand. After
installing, as
a test I ran an simple MPI program but it complains with following
errors.
[s4:10685] [0,0,0] ORTE_ERROR_LOG: Pack data mismatch in file
dps_unpack.c at line 121
[s4:10685] [0,0,0] ORTE_ERROR_LOG: Pack data mismatch in file
dps_unpack.c at line 95
Further digging with gdb prints following errors
[s7:07005] ERROR: A daemon on node s4 failed to start as expected.
[s7:07005] ERROR: There may be more information available from
[s7:07005] ERROR: the remote shell (see above).

any clue on what I am doing wrong ?
