Hi
Sorry to bring this subject up again -
but i have a problem getting xterms
running for all of my processes (for debugging purposes).
There are actually two problem involved:
display, and paths.
my ssh is set up so that X forwarding is allowed,
and, indeed,
ssh nano_00 xterm
opens an xterm fr
I've solved the problem by adding the flag RTLD_GLOBAL in the call to
dlopen() in function "sys_dl_open (loader_data, filename)"
(opal/libltdl/ltdl.c)
It seems that I need this flag. However when I run autogen.sh, I get the
following:

I compiled my mpi fortran code using the -mp option to verify that the
mpi code would still run. I get this message when I run
We have the checkpoint/restart working now. Turns out that the BLCR
kernel mods were installed incorrectly.
Thanks for the help.

Are there plans to provide an API that would allow a fault tolerant
enabled program to invoke checkpointing directly?

Not at the moment.
This would be a neat addition to Open MPI if application developers
see a need for it. There are many issues surrounding this type of a
feature (like any feature). Most of them surround what an application
expects and requires from such an API. One such question is whethe
Josh,
At this moment I´m working in the uncoordinated checkpoint, and
probably I´ll have some tools to collect data from the process and
environment and probably from the application.
About the application I´m considering the possibility to do something
like this (MPI_Checkpoint??).

The rank 0 received SIGTERM ... I wonder how this happens. Usually, we
don't just send SIGTERM around without a good reason. One of these
reasons might be that we detected a segfault, but then there is some
output.
Is that the complete output you get from your run ?
Thanks,
george.
Ok so I ask the mpirun masters how would you do the following:
I submit a job with torque (we use --with-tm) like the following:
nodes=4:ppn=2
My desired outcome is to have 1 mpi process per 2 cpus and use
threaded blas (or my own OpenMP take your pick)
Our cluster has some 4 core machines

For the above, -np 4 --bynod
We are testing for a specific line when looking for this patch:
test ! -z "`grep 'filename, LT_LAZY_OR_NOW' opal/libltdl/
loaders/dlopen.c`"; then
If this line is different in your dlopen.c, then it doesn't find it
and therefore autogen.sh doesn't patch it.
Did you already patc
