EuroPVM/MPI 2008 CALL FOR PAPERS

BACKGROUND
Hi Allan,
This suggest that your chipset is not able to handle the full PCI-E
speed on more than 3 ports. This usually depends on the way the PCI-E
links are wired trough the ports and the capacity of the chipset
itself. As an exemple we were never able to reach fullspeed
performance with

Dr. Yu sent me a version of this intended for OpenMPI back in September.
I was just today getting around to trying it, although I noticed that it
doesn't work with R v2.6, so my plans just changed a little.
If Dr. Yu gives permission, I'll send to you what he sent to me, or
perhaps he'll post it

Hate to be a party-pooper, but the answer is "no" in OpenMPI 1.2. We don't
allow the use of a hostfile in a Torque environment in that version.
We have changed this for v1.3, but you'll have to wait for that release.
Sorry

Tim,
Will OpenMPI 1.2.1 allow the use of a "hostfile"?

Open MPI v1.2 had some problems with the TM configuration code which was fixed
in v1.2.1. So any version v1.2.1 or later should work fine (and, as you
indicate, 1.2.4 works fine).

Jeff,
Here is the result of the "pbs-config". By the way, I have successfully
built OpenMPI 1.2.4 on this same system. The "config.log" for OpenMPI 1.2.4
shows the correct Torque path. That is not surprising since the "configure"
script for OpenMPI 1.2.4 uses "pbs-config" while the configure s
Well that's fun. Is this the library location where Torque put them
by default? What does "pbs-config --libs" return?
Also -- I second Reuti's question: what is the nature of your
requirement such that you need to be able to run outside of the nodes
that have been allocated to a job? Are

How about trying out 'PGAPack' then?

Okay, so are you experienced with parallel programming? What kind of
HPC applications are you looking for?
3-months back, I had no exposure to parallel programming.
Subsequently, I worked on a project

We have Torque as an mpi job scheduler. Additionally, I have some
users that want to modify the contents of "-hostfile" when they execute
"mpirun". To allow the modification of the hostfile, I downloaded OpenMPI
1.2 and attempted to do a "configure" with the options shown below:

Just to add. My whole cluster is intel em64t or x86_64 and with
openmpiv1.2.4 i was getting for two pc express intel gigabit and a
pciexpress gigabit ethernet Syskonnect @ 888, 892 and 892 Mbps measured
using NPtcp a sum total bandwidth of 1950Mbps on two identical different
systems connected
Hi,
I found the problem. It's a bug with openmpi v 1.2.4 i think. As below
tests confirm(AND an big THANKS to George!) I compiled openmpi v
1.3a1r16973 and tried the same tests with the same mca-params.conf file
and got for three pci express gigabit ethernet cards a total bandwidth
of 2583Mbp
