| Summary | 0015394: ParaView performance is poor, unstructured grid | ||||||||
| Description | ParaView performance is poor, unstructured grid. We should have someone take a look, and I have a good dataset that shows this. Please ask me for it. Dataset has 42 files, 42 blocks, Mode shapes, about 10 variables. 1.4 million cells, 1.6 million points. Note to myself: LargeTiedBlocks-UUR.tar.gz | ||||||||

Uploading a screenshot from loading this dataset, using VTune Amplifier. Note that total time is about 75 seconds, and over half of the time spent in GetCacheOrRead (31 seconds) is line 2663 (17 seconds), which I believe I fixed. |

Note in the uploaded screenhots, the important column is CPU Time: Self by Utilization. What time was spent in what function? I have highlighted any function that had more than 1 second. Total unoptimized is 76 seconds, optimized is 42 seconds. In theory, the compiler optimizer will also work better on the new code than the old code. Mainly what I did was remove calls in the bottom of loops that return a constant, heavy math in the bottom of loops that returned a constant, moving of data by byte, unrolled loops that always loop three times (horrible for branch prediction) (while protecting the code for the case that the loop doesn't loop three times). |
