| 20:27.53 | Notify | 03BRL-CAD:starseeker * 69196 (brlcad/trunk/src/librt/db5_io.c brlcad/trunk/src/librt/db5_size.cpp and 2 others): If we find out ahead of time what the largest bu_external ext_buf size is, we can allocate one bu_external with that large buffer size and re-use that same external object for *all* db get operations. Cuts about half a second off of the execution time for a large db5_size calculation test, although we |
| 20:27.55 | Notify | end up in effect creating local versions of several of the db_io functions that take a user supplied bu_external buffer object. |

| 20:30.54 | Notify | 03BRL-CAD:starseeker * 69198 brlcad/trunk/src/mged/edsol.c: Josh reported a crash - looks like the original size_t quellage and negative number casting in r42073 isn't happy on Windows. Try separating the state out into its own int variable and leaving the face number as a size_t. |
| 20:32.23 | Notify | 03BRL-CAD:starseeker * 69199 brlcad/trunk/src/libbn/randmt.c: randmt.c is LGPL licensed, but it looks like the original license from the code authors is BSD. Also, they've got a newer SFMT implementation which they claim is roughly twice as fast and has a better equidistribution property. May be time to revisit this, but need other opinions before proceeding. |
| 20:58.15 | Stragus | I can vouch for SFMT indeed being much faster, with a light touch of SSE2. Their code is a little messy though |
| 20:59.12 | Stragus | And it's written in a way that causes excessive memory spilling through multiple passes, I think the SSE2 could be faster |
