I'm sorry, I explained the problem very bad; we are using OSMesa library.
If we run pvserver only on the master node:
mpirun -np 2 pvserver --use-offscreen-rendering
It's all ok (even if DISPLAY variable is not set: we don't know if it's
necessary).
If we try to use 2 nodes (master and node1), running this command on the
master node:
mpirun -x
LD_LIBRARY_PATH=/home/user/ParaView/ParaView-bin/bin/:/usr/lib/:/home/user/ParaView/ComponentiAggiuntivi/lib
-np 2 -machinefile /home/user/ParaView/NodesList
/home/user/ParaView/ParaView-bin/bin/pvserver --use-offscreen-rendering
the error is:
Listen on port: 11111
Waiting for client...
Client connected.
[node1:06211] *** Process received signal ***
[node1:06211] Signal: Segmentation fault (11)
[node1:06211] Signal code: Address not mapped (1)
[node1:06211] Failing at address: 0x21
mpirun noticed that job rank 0 with PID 22632 on node master exited on
signal 15 (Terminated).
1 additional process aborted (not shown)
X is running on the second node (called node1); DISPLAY is not set neither
on node master nor in the second node.
Must X server run on each node and must DISPLAY variable to be set also if
we are using OSMesa library?
Must we install OSMesa on each node or it's enough to have installed that
library on a shared folder (/home/user/ParaView/Components/lib) in the
master node?
Have you any other idea?
Thank you very much for your patience
