I'll see what I can figure out.

I just cannot test this with my Macs since it appears that Apple wants everyone to use Metal instead of OpenCL and the Windows boxes I have are woefully underpowered WRT the GPU. I'll write a CPU only version for the command line.

If you publish the source (neatness doesn't matter all too much, not to me at least), I could try to debug / recompile...

I'm in there 39 times which matches my Leyland prime output. My indexing has advanced slightly to #1033 L(13260,4523). This sets up a big jump in three days.
