Dear Hammad,
Can you please have a RUN with "sufficiently Larger Problem Instance"? Then
see what happens!!
Sufficientmay be 10 times greater than that you used.
best regards,
Amjad Ali.

Hi,
If lib64 isn't there, try lib. That is,
export LD_LIBRARY_PATH=/home/jess/local/ompi/lib
Referencing the example that I provided earlier.

Hej vaibhav!
Assuming you use the official Ubuntu packages:

The library should exist under /usr/lib/libopen-pal.so.0 (which symlinks
to /usr/lib/libopen-pal.so.0.0.0 which symli
Hi,
I used the export command but it does not seem to work.It's still giving the
same error as
the lib64 directory does not exist in the ompi folder.
Any Suggestions.
Thank You,

Currently the openib BTL silently refuses to run when MPI_THREAD_MULTIPLE is
specified (ompi/mca/btl/openib/btl_openib_component.c:2367 in the current
trunk, r22822) which leads to confusing (to some people) error messages such as:

One more thing. The line should have been:
export LD_LIBRARY_PATH=/home/jess/local/ompi/lib64
The space in the previous email will make bash unhappy 8-|.

Hi,
It sounds like you may need to set your LD_LIBRARY_PATH environment
variable correctly. There are several ways that you can tell the
dynamic linker where the required libraries are located, but the
following may be sufficient for your needs.
Let's say, for example, that your Open MPI

I have installed openmpi on an Kubuntu , with Dual core Linux AMD Athlon

Hi Cole, Jed
I don't have much direct experience with PETSc.
I mostly troubleshooted other people's PETSc programs,
and observed their performance.
What I noticed is:
1) PETSc's learning curve is as steep if not steeper than MPI, and
2) PETSc codes seem to be slower (or have more overhead)
than c
I actually am only working on this code because it is what someone wants. I
would have probably chosen a different solver as well. We do have some vector
machines though that this will probably run on.
I did a lot of memory work already in the serial code to speed it up pretty
significantly.
Dear All,
Is this the correct forum for sending these kind of emails. please let me
know if there is some other mailing list.
Thank
