Hello, I have some problems with the memory footprint of Paraview 3.14.0. I run pvserver in parallel on 4 nodes of a cluster with 2 Paraview processes on each node. Each node has 16GB main memory. So in total I have 8 Paraview processes and 64GB main memory (distributed on 4 nodes).
For testing purpose I loaded a dataset in hdf5/xdmf format with the xdmf reader. The dataset is a simple uniform rectilinear grid with one float attribute. The size of the data is 16GB. After loading the data everything seems reasonable. Each of the 8 Paraview processes allocates about 2GB main memory. Then I create a contour. After that, each process allocates 2GB additional memory (resulting in 4GB for EACH of the 8 processes), although the memory inspector tells me that the generated contour is just 145MB. Then I create a slice (plane). Ones again, every process allocates 2GB additional memory (resulting in 6GB total for each process) for a simple plane (of 350MB). Of course, things are even getting worse when I try to load a 32GB dataset. Then every process allocates 4GB main memory, then 4GB in addition, and so on... Is there any solution for the strange behavior? Maybe I have to set some special cmake compiler flags?
