[Paraview] Running in parallel mode

[Emmanuel Colin]

Hi,

After some unsuccessfull tries with the CVS version of Paraview and
MPICH, I got ParaView06 to compile with LAM-MPI libraries on a Linux
cluster.

Trying to run it in parallel mode, it started to run (I got the ParaView
graphical loading widget), then decided it had better not... Here is the
output :

$mpirun -v -lamd -np 2 ./bin/paraview06/bin/ParaView
32268 ./bin/paraview06/bin/ParaView running on n0 (o)
1488 ./bin/paraview06/bin/ParaView running on n1
no display name and no $DISPLAY environment variable
MPI_Send: invalid tag argument: out of range (rank 0, comm 2)
Rank (0, MPI_COMM_WORLD): Call stack within LAM:
Rank (0, MPI_COMM_WORLD):  - MPI_Send()
Rank (0, MPI_COMM_WORLD):  - main()

  From the previous mails about parallel mode, I thought it might be a
DISPLAY environment variable problem. So I ran the same process on a
biprocessor system, and got a similar problem :

$mpirun -v -lamd -np 2 ./bin/PV06/bin/ParaView
22845 ./bin/PV06/bin/ParaView running on n0 (o)
22846 ./bin/PV06/bin/ParaView running on n0 (o)
MPI_Recv: invalid tag argument (rank 1, comm 2)
Rank (1, MPI_COMM_WORLD): Call stack within LAM:
Rank (1, MPI_COMM_WORLD):  - MPI_Recv()
Rank (1, MPI_COMM_WORLD):  - main()
-----------------------------------------------------------------------------

One of the processes started by mpirun has exited with a nonzero exit
code.  This typically indicates that the process finished in error.
If your process did not finish in error, be sure to include a "return
0" or "exit(0)" in your C code before exiting the application.

PID 22845 failed on node n0 with exit status 1.
-----------------------------------------------------------------------------

Thanks in advance for any hints at what the problem might be.
