主题： Re:Re: [Paraview] Paraview store all data in every server node?
Hi:
I used vtkXdmfReader to read my data(ParaView version is 3.4.0), and I also
found some information about my problem(XDMF bad memory use) from the mail
list. But I didn't find a final resolution for it.
My problem is, for example:
run: mpirun -np 4 ./pvserver
after reading data and rendering isosurface, each node(process) consume 2GB
memory
and run: mpirun -np 16 ./pvserver
after reading data and rendering isosurface, each node(process) also
consume 2GB memory
For this problem, I could't visualize large-scale dataset. Because if a
dataset could be visualized by one node, It also could be visualized by 16
nodes, but if it could't be visualized by one node, it also could't by 16
nodes(or more).
Maybe I should try ParaView 3.6.1. I will cry if the problem still exist in
version 3.6.1......

The problem may be the reader that you're using. Some of the readers in VTK
are not parallel so even if you run multiple processes each process will still
try to load the entire dataset in that case.

Hi all:
First thanks for Dave.Demarle's help.
I use "mpirun -np 4 ./pvserver" to launch a server with four nodes,
visualizing a 800*800*300 grid. It seems that each process consume too much
memory. So I extend the number of nodes from 4 to 8 using "mpirun -np 8
./pvserver" , but each process on 8 nodes server consume the same memory as 4
nodes server. The situation of 16 processes(16 nodes) is same as above.
I thought that with the number of processes' growth, each process on server
would share less raw data, so the quantity of memory each process consuming
would decline. It proved that I was wrong. Could someone tell me the reason?
Thanks for your help:)
