I had just updated the stats for OBD on my site, and so I believe that these are all correct but I could not verify against mersenne.ca. Guess it's good to have a backup... https://2721.hddkillers.com/

The site is presently down for maintenance (see https://www.mersenneforum.org/showpo...&postcount=119).

 2019-06-24, 17:41 #1169 James Heinrich     "James Heinrich" May 2004 ex-Northern Ontario 67128 Posts Yeah, sorry about that. When I did a test of the update locally it took 2m30s per table (with 10 tables) so I figured 20-30 mins downtime. But on the live server it's taking 20m per table so ~3.5 downtime, probably back online around 2000h UTC. confirmed: it will be back online by 2000h. Thank you for your patience. Sorry it took longer than expected. Last fiddled with by James Heinrich on 2019-06-24 at 19:54

87 to 88 bits took 5d 3h 23m 24.269s, so 2.0372 times as long (1.86% longer than expected).

Having used barrett87_mul32_gs, then barrett88_mul32_gs, the next range jumps up to barrett92_mul32_gs. Where the extra run time per class was fairly slight before, now it is much more significant at about 14% over barrett88_mul32_gs.

I'd estimate 88 to 89 bits will take ~11 days 17 hours and will finish on 9th July.

Since I'll be home soon, I won't continue to 90 bits on this one.

If you mouseover the "OBD Progress Level" text you see
Quote:
 There will be 23 steps from Level 21 to Level 22: getting candidate #22 to 87 bits and getting each candidate from 87 to 88 bits. Each of these steps will be indicated with a decimal point (21.01, 21.02, through 21.22, then 22.00)
The logic was derived from this post: https://www.mersenneforum.org/showth...301#post519301
Extending that a bit:
Quote:
 Level 23 will be 23 candidates trial factored to at least 89 bits. Level 22 will be 22 candidates trial factored to at least 88 bits. Level 21 will be 21 candidates trial factored to at least 87 bits. Level 20 will be 20 candidates trial factored to at least 86 bits. Level 19 is 19 candidates trial factored to at least 85 bits. Level 18 is 18candidates trial factored to at least 84 bits.
We have reached level 21.00 with at least 21 candidates at 87+ (there are 45).
Then to paraphrase lavalamp from the above post:
Quote:
 So 21.00 was 21 candidates at 87 bits, then we add on: +0.01 for 22nd candidate to 87 bits +0.01 * 8, since there are now 8 candidates at 88+ bits Making the current level 21.09.
