Wow, there are tons of info in that thread, but it may be dated. I'll run some quick tests to see if there are any major changes.
It appears you need to optimize the task's kernel size. EDIT: optimizing caused immediate Computation failure on 2 machines

A quick test un-optimized:
RTX 2080Ti - 220.68s GPU - 7.41s CPU (AMD 3800X) - Linux, nvidia-smi gives a reading of 94% GPU usage - 37,750.87 points
GTX 1080 - 708.16s GPU - 10.07s - CPU (AMD 3800X) - Linux, percent of GPU usage unknown -35,981.74 points
GTX 1070 - 845.15s GPU - 0.41s CPU (i7-5820k) Windows, 97% GPU usage - 36,033.20 points
R9-280X - 1,663.66s GPU - 68.45s - CPU (FX8320E) Windows, 93% GPU usage - 35,894.69 points
Optimized:
GTX 1070 - crashed
R9 280X - crashed
