I'm 'reviewing' my AstroPulse computation and trying new values for UNROLL
(Got to find me some info on this!)

I've started with unroll 1, 2, 4 and now 8, with ffa_block=10240, ffa_block_fetch=
2048.

Takes over 3 hours for an AstroPulse is done, with these settings.
But % update is slow, as is the GPU load heavily spikes, also the best result, for now.
Will try 16, 32, {64, 128} as unroll.
With unroll=8, ffa_block & block_fetch, as mentioned above, after 1 hour, it has done
14,474% and estimated time has dropped from 34 hours to 29 hours.

Eh, this is the SETI@home Enhanced Sub-Forum, Not the Astropulse Sub-Forum,

If you find that Sub-Forum is Empty, that is because the Focus at the moment is getting Seti@home v7 ready for release.

I don't find it empty and do know that getting SETI@home V7, up & running, has priority, but it clearly states: FORUM: AstroPulse .

Claggy was absolutely correct at time of writing.
Just because you are in the right forum now doesn't mean you started out in the right one.

Regarding updating % done - that is intentional. Raistmer doesn't want to waste too many cycles on updating that frequently. Better go by completion times and remember they depend on % blanked.

My bad, you are both right, so I apologize for my rude answer.
