Hi Andy,

D'oh! sorry, pvbatch does work as expected.

Hi Mark,

Is that a typo or are you really using pvpython? You said "aprun -n 32 pvpython myscript.py". Otherwise I don't see anything that shouldn't work.

Best,
Andy

Hi ParaView,

When using the client GUI, Save Data will write out a pvti/vti data set with a vti for each processor. When trying this with pvbatch I'm only getting a single vti. I'm calling the pvbatch with

aprun -n 32 pvpython myscript.py

which I think should generate 1 pvti and 32 vtis. This is using ParaView 4.1.0.

myscript.py is a hack, I'm reading a pvti that's split into 8192 vtis and trying to re-write out fewer, say 32 or 64. This is part of troubleshooting what I think might be a lustre issue.

# myscript.py
try: paraview.simple
except: from paraview.simple import *
servermanager.Connect()
reader = XMLPartitionedImageDataReader(FileName=['test-input.pvti'])
writer = XMLPImageDataWriter()
writer.Input = reader
writer.CompressorType = 'ZLib'
writer.FileName = 'test-output.pvti'
writer.UpdatePipeline()

Is what I want to do possible? If not, is there a recommended way to merge vtis?
Mark
