Hello,
I am having trouble with the *** Assembler section of the GNU autoconf
step in trying to build OpenMPI version 1.6 on an HP AlphaServer GS160
running Tru64unix version 5.1B-6:
# uname -a
OSF1 zozma.cts.cwu.edu V5.1 2650 alpha
The output is of the ./configure run
zozma(bash)% ./configure
Hello Jeff,
thank you very much for your help. You were right with your suggestion
that one of our system commands is responsible for the segmentation
fault. After splitting the command in config.status I found out that
gawk was responsible. We installed the latest version and now
everything

Yes, it works! Thank you very much for your help.

Try: ps -elf | grep hello
This should list out all the processes named hello.
In that output is the pid (should be the 4th column) of the process and
you give your debugger that pid. For example if the pid was 1234 you'd
give "gdb - 1234".
Actually Jeff's suggestion of this being a firewall
Exxxcellent.
Good luck!

Another sanity think to try is see if you can run your test program on
just one of the nodes? If that works more than likely MPI is having
issues setting up connections between the nodes.

Hello Duke,
Welcome to the forum.
The way openmpi schedules by default is to fill all the slots in a
host, before moving on to next host.

Hi folks,
Please be gentle to the newest member of openMPI, I am totally new to
this field. I just built a test cluster with 3 boxes on Scientific Linux
6.2 and openMPI (Open MPI 1.5.3), and I wanted to test how the cluster
works but I cant figure out what was/is happening. On my master node,
14 matches
