Edit: Doubleclicking buttons is a hard habit to break.

Probably on about 0.75% waiting now... Quickly, horde DC tasks!!! Joking, of course.

Going to stick with SoB and forgo any practical chance of the P_2019 badge.

I suppose it's Red or Bust this year. And, more likely than not, bust.

Absolutely not. If I were lucky, SOB would have ended before this forsaken thing showed up over there <---

Heck if 10% of the tasks left on machines from the challenge return results instead of timing out I'd take it.

No sharp rise in the Waiting% post challenge is encouraging.
7) Message boards : General discussion : Current prices of RTX 2080s vs GTX 1080s (Message 124632)
Posted 514 days ago by Andy
I believe it is expected that there will soon be GTX 11xx cards equivalent less the ray tracing functionality, which isn't yet supported by a damned thing (and halves your performance to boot when turned on) for a lower price than RTX cards.

This makes the RTX cards sell poorly... and imo provides a plausible cause of the price cuts.

Have we gone below 50% work waiting yet?

n=25m, 181 done, 0 bad

~~If we take an independent model, the accuracy such that 181/0 has a 50/50 chance to occur is about 99.62% (0.38% incorrect results). In reality, there is likely some dependence (a bad PC will likely return more than 1 bad result...) but that's impossible to quantify.

If there truly was a doublecheck in this range that matched residues already, it's a shame it wasn't documented -- if this carries on through a significant portion of the remaining residue-only checks, this is a lot of work that we're 100% required to waste, as much as 15% of the DC. ~~



Just noticed, as I was writing, that I have 2 pending inconclusives from (send date) April 22 and April 26, which must be from the n=25m range (since there were 0 waiting n=24m tasks on April 21). Looks like none of the bad results have managed to find 2 fast multithreaded machines, not that all the residues are correct.

In fact... one is on a borderline malicious machine (http://www.primegrid.com/results.php?hostid=899451) grabbing hundreds of tasks, and letting them time out... I doubt the owner realizes what it's doing since their other machines are behaving fine.
