[Paraview] problem starting the pvserver

[Moreland, Kenneth]

I am a bit confused by your question.  Are you saying the first example works and the second does not?  I am also confused by what you are trying to set up.  Are you trying to run the server on one of your machines and the client on the other, or are you trying to run a parallel server using both machines?

In the second example, it looks like your OpenMPI install is messed up.  In the 4th line (1st error), it complains about not finding orted, which is a daemon that the OpenMPI version of mpirun uses to launch processes.  It does not look like pvserver is being run at all.

I cannot claim to have a lot of experience in setting up MPI installs, especially ones on heterogeneous nodes like you are setting up.  My advice would be to first make sure that you can launch a job "locally" on each machine, then try to launch a job only one the opposite computer (i.e. launch only on the 32 bit machine from the 64 bit machine and vice versa), and then finally launch a single job on both.

Hi all,

i managed to compile the paraview 3.4.0 in both a 64bit dual core machine and a 32bit quad core machine.
having trouble starting the pvserver when linking 2 machines. Below are the konsole lines..

yewyong at frodo:~/installer/ParaView-3.4.0_build/bin> ../../openmpi-1.2.8_build/bin/mpirun -hostfile ../../openmpi-1.2.8_build/etc/frodo -np 2 ./pvserver --use-offscreen-rendering
Listen on port: 11111
Waiting for client...
^Cmpirun: killing job...

mpirun noticed that job rank 0 with PID 27000 on node 192.168.0.16 <http://192.168.0.16>  exited on signal 15 (Terminated).
1 additional process aborted (not shown)

everything looks good when there is no linking of 2 machines. (this is the 64bit dual core machine)
but,

yewyong at frodo:~/installer/ParaView-3.4.0_build/bin> ../../openmpi-1.2.8_build/bin/mpirun -hostfile ../../openmpi-1.2.8_build/etc/frodo_quadcore -np 6 ./pvserver --use-offscreen-rendering

mpirun was unable to cleanly terminate the daemons for this job. Returned value Timeout instead of ORTE_SUCCESS.

i can't start the pvserver when involving 2 machines.
192.168.0.16 <http://192.168.0.16>  = 64bit dual core
192.168.0.10 <http://192.168.0.10>  = 32bit quad core

Anyone faced this before?
Thanks in advance for helping.

Cheers,
yewyong
