Summary

0012726: CTH variable memory use is inefficient and wrong

Description

ParaView 3.12.0, remote server (8 processes), Linux client.
* Start ParaView. Open Dave's large CTH program (256 files).
* Turn off "compute derived variables".
* Apply (note that we have not added any variables)
* Surface. (No idea why this seems to matter, 30 mbytes will be used, each process).
* ssh into the node we have. Do "top". Note the memory for each pvserver, as well as the total. I get the following: 2.19 GBytes used total, RES of 135 MBytes for each of the 8 pvservers.
* Note that the Information tab states that 3.6 MBytes are in use. There are 3.5 million cells and 4.7 million points.

* So far, so good.

* On the Properties tab, load Material Volume Fraction 1.
* Information tab states that we are using 7.2 MBytes.
* Top states that 2.32 GBytes total is used on the node - an increase of 130 MBytes of memory use! Each process has grown to 151 MBytes, thus about 15*8=120 MBytes is in use! In theory, the Information tab is correct - we should have malloced about 3.5 million bytes.

This is killing very large visualizations on Cielo. It needs to be fixed ASAP.
