Hello all,
I’m trying to use paraview in parallel. For that I’ve got a self-compiled
paraview version 3.14 and I use client/server mode.
In paraview I use these settings: use multicore, remote render threshold
(100MByte), client outline threshold (0MByte) and interactive subsample rate
(2pixels).
I’ve got unstructered test data. The data was created in four processes as
*.vtu file (4times 352MByte) or as a whole *.pvtu file.
So I start with ssh the pvservers on the server (there are 48cores on the
server) with
mpirun –np ‘number’ ../pvserver –display localhost:0
and then I connect via my PC to this server (there’s a ethernet cable with
1GB/s between server and PC).
I tried different numbers of pvservers (2,4,8 and 16).
I loaded the data and used different filters like wireframe, contour, slice and
clip and I moved the data around (with drag and drop).
But I could only see a little improvement in the time of representation (e.g.
the contour filter took 5.3s on 4pvservers and 5s on 16pvservers).
I thought I could see a greater improvement.
So why do I see no improvement or when can I see an improvement? Or am I doing
something wrong?
Also I’m surprised that it took lesser than 4 times as long when I use the
whole data in compare with only a fourth of the data.
e.g. on 16 pvservers it took 6s to change the representation of a fourth of the
data to wireframe and it took 20s for the whole data
Why is this happening?
Thank you for your help.
Greetings,
Kevin
