This is a benchmark post with speeds for Kangaroo GPU Solver. All the tests were made with default DP and default grid size (calculated by a program). I guess that some plays with DP and grid size could change (increase or decrease) the speed. If somebody knows the optimal values, please let us know.

Code:

Card Model Grid size DP Tested speed
---------------------------------------------------------------
GTX 1050 Ti Grid(12x256) DP 16 115 MKey/sec
GTX 1080 Ti Grid(56x256) DP 15 500 MKey/sec
Tesla T4 16Gb Grid(80x128) DP 14 565 MKey/sec
RTX 2080ti 11Gb Grid(136x128) DP 13 1225 MKey/sec
Tesla V100 32Gb Grid(160x128) DP 13 1420 MKey/sec
---------------------------------------------------------------

The program uses an algo to calculate the best DP to use to NOT increase the DP overhead. very low DPs (like 0 or 1 or 2) may slow the speed somewhat due to writing pretty much every point and distance into RAM, but other than that possibility, the program gets the same speed regardless of DP size.
