| 11:39.46 | Stragus | Aprtm: Learn the basics of OpenCL, write the function in a way that's friendly to GPU parallelism, and test it |
| 11:41.14 | Stragus | I'm not a mentor, but I can help with any question regarding writing good GPU code |
| 11:43.46 | Stragus | At first glance, the data memory layout and branching would have to be modified (to get good performance) |
| 11:46.52 | *** join/#brlcad Lord_of_Codes (~Lord_of_C@122.163.195.246) |
| 11:47.46 | Stragus | Gah, I was looking at the OpenCL code sample rather than the C. brlcad, that's some very slow code |
| 11:50.29 | Stragus | Parallel memory loads/stores have a large stride, they aren't coalesced or packed, there are local memory writes through that hitp pointer, branches should be minimized to improve parallelism (call do_segp() only once with the swapped arguments, not twice) |
