[Paraview] Linux memory problems exclusive to Paraview

[Dennis Conklin]

All,

I will never be mistaken for a Linux sys admin, so let me try to tell you what is happening in a hopefully understandable way.

We run Paraview standalone on our workstations - no  remote server, etc.   Just running the executables DL'ed from the website.

We constantly have an issue with Paraview not having enough memory to behave properly.
If I run TOP at the command line, I might see that nothing is using more than 2% of memory, but in the header it says I have 32GB of ram and 28GB is "used" in the terminology of TOP.   This will mean that Paraview will have very little memory available to it (confirmed using Memory inspector) and it will be very slow!     However, other programs, including other post-processors seem to be able to access this "used" memory and perform much better.    What is it about Paraview which makes it unable to utilize this "used" but apparently available memory, while other programs can?

If more info is needed, can someone help me understand how to get the needed info.   After discussing this several times with the sys admins, they just want me to go away because apparently only Paraview has this issue.

Thanks for any help

Dennis
