[Paraview] Fluent files breaking ParaView?

[Ian Grimstead]

Hi,

I've just built the CVS wavefront (this morning, in fact) of ParaView on our
cluster (8 of dual-core dual-socket opteron, each with 8Gb memory and NVidia
fx4500 GPUs, running RHEL 4, update 6). I launched the latest Windows
client, and fed it a FLUENT datafile. I've built the MPI version (using
voltaire's stack), and run it across 8 nodes. Each node is launched as a
"pvserver". Started up fine, started reading the file...

After a long delay, ParaView blew with an "out of memory" error. Oh my
goodness, it had tried using ~8Gb of memory on each node. Detail as follows:

----8<--------8<--------8<----
Process id: 0 >> ERROR: In
/sge/share/common/ParaView-cvs/ParaView3/Servers/Common/vtkProcessModule.cxx
, line 1281
vtkProcessModule (0x38c6d80): Exception: Insufficient memory exception.
----8<--------8<--------8<----

The original FLUENT file was (allegedly) ~400k points. Cas file was 38Mb,
dat file was ~300Mb. Also tried another large FLUENT file (47Mb CAS, 35Mb
DAT), similar result:

----8<--------8<--------8<----
Process id: 0 >> ERROR: In
/sge/share/common/ParaView-cvs/ParaView3/Servers/Common/vtkProcessModule.cxx
, line 1281
vtkProcessModule (0x38c6d80): Exception: Insufficient memory exception.

  what():  St9bad_alloc
[mpirund] rank 5 has got signal 6
terminate called after throwing an instance of 'std::bad_alloc'
  what():  St9bad_alloc
----8<--------8<--------8<----

Has anyone else tried large FLUENT datasets? Any advice gratefully
appreciated, we're trying to view these files as a favour, so I have pretty
much 0 idea of what's in them until I can actually visualize them...

Should I try running several render servers and separate data servers?

Thanks!

Ian
