It is fully implemented, but on my development branch at the moment. We hope
to bring that over to the trunk late Jan - primarily need to complete some
work on MPI-2 dynamic process management and give Josh a chance to repair
the checkpoint/restart functionality before we bring it over.

O
Ralph,
Thanks for the clarification as I'm dealing with workarounds for this at
Sandia as well...
I might have missed this earlier in the dialog, but is this capability
in the SVN trunk right now, or still on the TODO list?

Open MPI 1.3 will support use of the hostfile and the tm launcher
simultaneously. It will work slightly differently, though, with respect to
the hostfile:
1. PBS_NODEFILE will be read to obtain a complete list of what has been
allocated to us
2. you will be allowed to provide a hostfile for each
Ralph,
Thanks for the information. I am assuming OpenMPI 1.3 will support the
"-hostfile" without the extra parms. Will 1.3 also carry the same
restrictions you list below?

FYI -- all of Open MPI's electronic resources will be offline for half
of Dec 26 for some scheduled maintenance. Please see below for details.

Wow, I'm amazed... it just works "out-of-the-box" configured with
with-openib. I guess the new kernel supplies everything I need.
Thanks a bunch for the clues.

Hi,
I have the same error message when fault tolerance is activated.
I'm using gcc version 4.1.3, with Ubuntu 7.10 (i686) (kernel
2.6.22-14-generic)

Just to be clear: what this does is tell Open MPI to launch using the SSH
launcher. This will work okay, but means that Torque doesn't know about the
children and cannot monitor them. It also won't work on clusters (such as
the ones we have here) that do not allow you to ssh procs onto the backend

Glad to hear that worked for you.
Full credit goes to Brock Palen who told me about this. It turns out we also
have a user who wanted to do that. And meta-credit goes to the OMPI developers
for making a consistent and flexible set of MPI tools and libraries.

Andrew,
That worked like a champ. Now my users can have it both ways. For the
record, my control statements looked like the following:
/opt/openmpi-1.2.4/bin/mpirun -mca pls ^tm -np $NP -hostfile $PBS_NODEFILE
$my_binary_path
My job works just fine and reports no errors. This version of Open
It's a pretty hazy difference; I don't think there are formal

Cluster computing *usually* (but not always) implies a bit more
tightly coupled set of computing: the app communicates and coordinates
between itself more than your standard manager/worker computation

In general, you need a functioning IB subsystem on your machines for
OMPI to build for and use IB. This includes both the set of kernel
drivers and the userspace libraries. In particular, Open MPI v1.2
uses the "ibverbs" library. If OMPI can find the ibverbs library and
headers during it
Brian,
Here is how I do it:
./configure --prefix /opt/openmpi-1.2.4 --with-openib=/usr/local/ofed \
--without-tm CC=icc CXX=icpc F77=ifort FC=ifort \
--with-threads=posix --enable-mpi-threads

Terry,
Your suggestion worked. So long as I specifically state "--without-tm",
the OpenMPI 1.2.4 build allows the use of "-hostfile". Apparently, by
default, OpenMPI 1.2.4 will incorporate Torque if it exists, so it is
necessary to specifically request "no Torque support". I used the normal

I have been using OpenMPI for quite a while now, and its working out great.

I am a bit hazy about the differences between Distributed Computing
and Cluster Computing.
This document here
http://www.ibm.com/developerworks/grid/library/gr-heritage/ is a nice
read on Grid Computing and it also has few lines about important
differences from Cluster Computing.
