Any option on server side to send a few wus to clients so to have some buffer or the only option would be to increase sieve range once again to 4k or even 8k.

Is there any way that the [url]http://factoring.cloudygo.com[/url] could record 'relations in last 24 hours' as well as 'relations since the project started' - it would make it rather easier to see what happens when configurations change.

None that I know of for buffering. What does "only option" refer to?

As for workunit size, we'll be changing that to 8k or 10k when we move to I=15, as yield drops from 6.x on I=16 at ~200M to 2.2 on I=15 at ~300M.
So far, we have sieved Q from 8M to 68M for 533M raw relations, for an average yield of 8.9. The yield on current WUs is in the mid-8's.

I'll run remdups shortly to see what our duplicate rate looks like.
EDIT: For Q from 8-60M, 349.5M unique, 118.5 duplicates, 0 bad relations, total 468M relations. Duplicate rate 25%, better than the C206 that Greg ran on 16e/33 for us (that one was 792M uniq, 373M dup).
I'll run it again when Q reaches 70M.

I'd like this too. Perhaps replace the timestamp of last workunit with this stat? We can see the project-difficulty trend as our numbers gently slide, see who is new and rising fast, and as fivemack said easily quantify changes in client configuration.

I'll try to add it to the top line and graph page tonight.

Done

(which is under Charts tab) also a number on the first page.

The daily_r curve is useful, because differentiating the total-work-done curve by eye isn't really possible; thank you

I think it would be even more useful to have the last-24-hours figure at a per-client level.

pinhodecarlos 2019-06-23 09:14

What about associating the clients to teams?

Some thoughts on hyper-threading and -t lots
 
Median runtimes in various configurations, on the same hardware (fortunately I have three identical computers)

[code]
One job -t32 1090s = 2180s for two
Two jobs -t8 2132s/2
Two jobs -t16 taskset 0-15; 16-31 1742s/2
Two jobs -t16 taskset 0-7,16-23; 8-15,24-31 1915s/2
[/code]

So, on these dual-socket eight-core machines, the right answer is to run two jobs, one across both sockets and the other on the other hyperthread across both sockets ; I think I'd expected two jobs to be better than one but am a bit surprised that having both jobs use both sockets is significantly better.

We've reached Q=70M, so I re-ran remdups:
[code]Q Unique Dup Total
8-60M 349.5 118.5 468.0
8-70M 402.4 147.7 550.1[/code]

Q=60-70M added 82M relations, but only 53M unique.

[QUOTE=SethTro;519664]Vebis has ~10 clients (vebis.1, vebis.2, ...) so I joined all of those to vebis.<X>

I'm going to join all your clients into lukerichards.<comp> for the main tab and then add a new tab for all clients[/QUOTE]

Is there any way to add instance-1, localhost and lrichards-pre2core to this collection as well, so I can see my complete combined stats without mental arithmetic?

Thanks.
