Hi all,
I explained the problem I'm facing @ http://www.ideone.com/EGMMn
please help
thanks
Hi,
The job queue has a time budget, which has been set in my job script.
For example, my current job queue is 24 hours.
But, my program got SIGKILL (signal 9) within not more than 2 hours since it
began to run.
Are there other possible settings that I need to consider ?
thanks
Jack

If your program runs faster across 3 processes, 2 of which are local to each
other, with --mca btl tcp,self compared to --mca btl tcp,sm,self, then
something is very, very strange.
Tim cites all kinds of things that can cause slowdowns, but it's still very,
very odd that simply enabling using t

You need to talk to your local administrators and ask them why Torque is
killing your job. Perhaps you're submitting to a queue that only allows jobs
to run for a few seconds, or something like that.

I checked that this issue is not caused by using different compile
options for different libraries. There is a set of libraries and
executable compiled with mpif90, and this warning comes for
executable's object and one of libraries...

This might not have anything to do with your problem, but how do you
finalize your worker nodes when your master loop terminates?

It means that Torque is unhappy with your job - either you are running longer
than it permits, or you exceeded some other system limit.
Talk to your sys admin about imposed limits. Usually, there are flags you can
provide to your job submission that allow you to change limits for your program.
Hi, I have figured out how to run the command.
OMPI_RANKFILE=$HOME/$PBS_JOBID.ranks
mpirun -np 200 -rf $OMPI_RANKFILE --mca btl self,sm,openib -output-filename
700g200i200p14ye ./myapplication
Each process print out to a distinct file.
But, the program is terminated by the error

I know OpenMPI uses /tmp directory to allocate shared memory
This is my machinefile
node-1-16 slots=2
node-1-17 slots=2
node-1-18 slots=2
node-1-19 slots=2
node-1-20 slots=2
node-1-21 slots=2
node-1-22 slots=2
node-1-23 slots=2
Each cluster node has 2 processors. I launch my application with 3
processes, one on node-1-16 (manager) and two on node-1-17(worke
Hi,
My application performs good without shared memory utilization, but with

I know OpenMPI uses /tmp directory to allocate shared memory and it is in
the local filesystem.
