I have various boxes that run openmpi and I can't seem to use all of
them at once because they have different CPU's (e.g., pentiums, athlons
(both 32 bit) vs Intel I7 (64 bit)). I'm about the build 1.4.3 and was
wondering if I should add --enable-heterogenous to the configure flags.
Any advice as

I'm using mpirun and the nodes are all on the same machin (a 8 cpu box
with an intel i7). coresize is unlimited:
ulimit -a
core file size (blocks, -c) unlimited

, but this doesn't explain why the node calling
abort doesn't exit with a coredump.

I've got a mpi program that is supposed to to generate a core file if
problems arise on any of the nodes. I tried to do this by adding a
call to abort() to my exit routines but this doesn't work; I get no core
file, and worse, mpirun doesn't detect that one of my nodes has
aborted(?) and doesn't
That did it. Thanks.

I've got a mpi program on an 8-core box that runs in a master-slave
mode. The slaves calculate something, pass data to the master, and
then call MPI_Bcast waiting for the master to update and return some
data via a MPI_Bcast originating on the master.
One of the things the master does while th

I'm using openmpi (1.3.2) to run on 3 dual processor machines (running

the 3rd is connected to my LAN via VPN and NAT (I can communicate in
