| 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. | ||||||||

I just tested this, and it is much, much better. Closing it. |
