Thanks
I have downloaded http://padb.googlecode.com/files/padb-3.2-beta1.tar.gz
and followed the instructions of INSTALL file and installed it at
/mypath/padb32
But, I got:
-bash-3.2$ padb -Ormgr=pbs -Q 48279.clusterJob 48279.cluster is not active
Actually, the job was running.

can you install MPI on your local machine? As someone said earlier, you
don't need a cluster to run MPI. You can run MPI with multiple processes on
a single computer.

The -a flag is a shortcut to all jobs, if you are providing a jobid (which is
normally numeric)
Also, btw using these two values and make clean, I was able to both
configure and build Open MPI properly. After that I compiled an example
code with -m32 flag and it compiled properly too :D. It remains to be seen
whether my setup of machines run them properly or not.

ThanksI have downloaded http://padb.googlecode.com/files/padb-3.0.tgz
and compile it.
But, no user manual, I can not use it by padb -aQ.

Actually, myjob is running in the queue.
Do you have use manual about how to use it ?
thanks
Ralph, well my --host flag contains i686-pc-linux-gnu and so does --build.

The problem is that you set the build and the host to the -same- architecture -
that indicates it isn't a cross-compile situation. The --host flag should
indicate the arch of the machines that will run the code - in your case, that
would be i386-pc-linux-gnu

Make sure to "make clean", too -- just to clean up any kruft that may be left
over from a prior build that is not necessarily compatible with your new set of
configure/build/link options.

I think you are missing the --host flag, so it still thinks it is building for
the current machine.

I also tried by adding

alongwith the --build option. Same error :(

You might also need LDFLAGS=-m32 ...?

Your job may be queued, not executing, because there are no
resources available, all nodes are busy.
Try qstat -a.
Posting a code snippet with all your MPI calls may prove effective.
You might get a trove of advice for a thrift of effort.

Do ./configure --help and you'll see options for specifying the host and build
target. You need to do that when cross-compiling.

I use qsub -I nsga2_job.shqsub: waiting for job
48270.clusterName to start
By qstatI found the job name is none and no results show up.
No shell prompt appear, the command line is hang there , no response.
Any help is appreciated.

You don't need a cluster to run MPI jobs, can you run the job on whatever
you development machine is? Does it hang there?

Can you use the interactive mode of PBS to get 5 cores on 1 node? IIRC, "qsub
-I ..." ?
Then you get a shell prompt with your allocated cores and can run stuff
interactively. I don't know if your site allows this, but interactive
debugging here might be *significantly* easier than try to auto

I have to use #PBS to submit any jobs in my cluster. I cannot use command line
to hang a job on my cluster.
this is my script: --#!/bin/bash#PBS -N

Is it not possible to reproduce locally? Most clusters have a way to submit
an interactive job (which would let you start this thing and then inspect
individual processes)

You can use the command "padb -aQ" to show you the message queues for your

Would like to tell me how to use
(gdb --batch -ex 'bt full' -ex 'info reg' -pid ZOMBIE_PID)
in MPI ?
I need to use #PBS parallel job script to submit a job on MPI cluster.
Where should I put the (gdb --batch -ex 'bt full' -ex 'info reg' -pid
ZOMBIE_PID) in the script ?

This really doesn't prove that there are no outstanding asynchronous

Thanks, the problem is still there.
I used:
cout << "In main(), I am rank " << myRank << " , I am before

I think I got this problem before. Put a mpi_barrier(mpi_comm_world) before
mpi_finalize for all processes. For me, mpi terminates nicely only when all
process are calling mpi_finalize the same time. So I do it for all my
programs.

Thanks, But, I have put a mpi_waitall(request) before

If the above sentence has been printed out, it means that all requests have
been checked and finished. right ?
What may be the possible reasons for that stuck ?
So what you are saying is *all* the ranks have entered MPI_Finalize
and only a subset has exited per placing prints before and after
MPI_Finalize. Good. So my guess is that the processes stuck in
MPI_Finalize have a prior MPI request outstanding that for whatever
reason is unable to complete

I used:

I can get the output " I am rank 0 (1, 2, ) I am before MPI_Finalize() ".
Are there other better ways to check this ?
