Yes as I said, I tested (i.e. measured) with ROCm 2.10. Should not regress on other platforms, but I'm looking for feedback on this. If a regression is detected (e.g. on Nvidia) I'll switch the change on/off as appropriate.

Coded for and test on are two separate distinctions. Thanks for all you do.
This is timely, as I was just considering rolling through a slew of gpu models with gpuowl minor updates and -use options timing script updates on PRP.

Only ran -h so far, but here it is. This is the latest commit at the moment, that has Preda's P-1 stage 2 tweak.

I have just downloaded a bunch of world record PRPs and some end in 0 and others end in 2. Will "program":{"name":"gpuowl", "version":"v6.11-124-g267cc60"} perform P-1 automatically on those ending with "2" or do I need to upgrade gpuOwl?

Yes, that version is after the automatic P-1 commit, so you should be fine. However, the latest commit from 2 days ago implements a change that results in a 33% speed improvement in P-1 stage 2.

Correction, it's 33% speed-up of one kernel (tailFusedMulDelta) that was taking up 45% of stage-2 time before. So it's more like a 12% speed-up of the stage2 (I hope).
