[Paraview] XDMF Join Strided: Memory Footprint

[Huebl, Axel]

Hi,


I am experiencing a huge temporal memory usage by loading xdmf/hdf5 data
strided with "join" (see attached file).

While loading the "join-ed" data set, the memory usage pops up to very
high levels and when it is finished (the gui starts to react again) it
shrinks down to around few percent of it.

I am loading the "Function=JOIN(...)" set with striding "8 8 8" with
paraview which makes me wonder if the striding might get ignored for the
initial load period?

I tested the same by loading the individual components of the vector
field, each with striding, and using the "Calculator" filter to generate
the vector field.
By that the memory usage stays at a low footprint all the time.


Best regards,
Axel Huebl
