I'm afraid the 1.5 series doesn't offer any help in this regard. The
required changes only exist in the developers trunk, which will be released
as the 1.7 series in the not-too-distant future.

I'm afraid not, even with the changes in the developer trunk. What happens
is that the local and node ranks for each mpirun start over at 0 because
the instances of mpirun don't know about each other. PSM uses the local
rank as an index for determining endpoint. So running multiple mpiruns on
the s
Thanks guys.
Using absolute path of mpirun fixes my problem.
Cheers

The offending file: openmpi/contrib/vt/vt/vtlib/vt_cudartwrap.c
is easily fixed with placing a const in front of the void *ptr
for the cudaPointerGetAttributes wrapper code segments.
Then the openmpi 1.5.5 release compiles with Cuda 4.1

Hi Shiqing, i haven't yet find a solution and for the record, i have installed
openmpi from an executable on windows 7(i don't know if i mentioned that
before). at first, i had an error message while compiling the hello world
application : unresolved link or something like that, then i added

Sorry to hijack the thread, but I have a question regarding the failed PSM
initialization.
Some of our users oversubscribe a node with multiple mpiruns in order to run
their regression tests. Recently, a user reported the same "Could not detect
network connectivity" error.
My question: is th
I'm not sure the 1.4 series can support that behavior. Each mpirun only knows
about itself - it has no idea something else is going on.
If you attempted to bind, all procs of same rank from each run would bind on
the same CPU.
All you can really do is use -host to tell the fourth run not to use

Hi there,
I'm encountering a problem when trying to run multiple mpirun in
parallel inside
one SLURM allocation on multiple nodes using a QLogic interconnect
network with
PSM.
I'm using Open MPI version 1.4.5 compiled with GCC 4.4.5 on Debian
Lenny.
My cluster is composed of 12 cores nodes
Hi,
I'm benchmarking our (well tested) parallel code on and AMD based system,
featuring 2x AMD Opteron(TM) Processor 6276, with 16 cores each for a total of
32 cores. The system is running Scientific Linux 6.1 and OpenMPI 1.4.5.
When I run a single core job the performance is as expected. How

Yes, I am trying to run the program using multiple hosts.
The program executes fine but *does not use any slaves* when I run
*mpirun -np 8 hello --hostfile slaves*
The program throws error saying *shared libraries not found* when I run
* mpirun --hostfile slaves -np 8*

Were you trying to run the MPI program on a remote machine?? If you
are, then make sure that each machine
16 matches
