Really it’s a block offset, like 8.5 mil or 9 mil.
In case of compiler issues (for wich software work-arounds may not possible) are not enough. AMD has been involved in the "bogus period" issue since Jan 2019.
We're on July ... and if not for the #pragma unroll 2 the issue would still be there.
So it’s to gauge the propow periods speed and implemenations stability in translating the instructions into their GPU stack.
We had already done all of that ... but the "illuminati" community didn't give a shit about that. No surprise me, and all others involved, have withdrawn their work and there is no more gangnam network.
no mechanism to tweak parameters mid-blockchain (yet)
Changing ProgPoW knobs mid-blockchain possible/being explored as implied by the (yet)?
I was wondering if it would make sense to use the Ravencoin 'nibbles' technique to randomly choose values for ProgPoW's knobs (knob nibbling?). Broadcast the values in the extra-field set of the block for miners. You wouldn't need to consider changing the values to thwart theoretical efficient fixed function hardware because the values would be changing constantly.
