[Paraview] RE : something doesn't work well ?

[BOUSSOIR Jonathan 167706]

Hi Berk,

I don't think the problem is in the script or vtk file, because I have done many test.

I use a cluster type Beowulf with diskless via nfs. Only the master has disk-dur.
I see that the problem is nfs.
I tried to make the vtk file in a ramdisk but I have always the problem, sometime it run fine sometime not.

I had done a test without diskless, it run fine.
But I would like to install paraview on this cluster (32 PC with 4cpu each)
Somebody have a idea on what is the probleme ?
And how I can to solve my probleme ?

Thanks in advance for your kind help.

Regards, 
Jona

Hi Jona,

If I were to make a guess, I would say that the file caching done by
the OS is why your script runs sometimes faster. I see a huge
difference in performance when loading a large file the second time in
ParaView. It is hard to say more without having the data and the
script.
