1) Message boards : Number crunching : How to compare performance for a particular sub-project (Message 143651)
Posted 8 hours ago by Profile Michael GoetzProject donor
Let's say I want to crunch SOB. And I want to compare my computer's performance against the rest of the field for that sub-project. Specifically, I want to see what machines are fastest, and then drill down to see their configs (and threads per task). Is there a way to show all results and filter by sub-project?


Unfortunately not.

I can't even do that manually querying the database. At least not if I want to get solid, reliable results.

The reason I don't even try to get that information for myself, let alone make it available to users, is that the signal to noise ratio is so low as to make it almost useless.

While I can see the CPU models, and with some difficulty can see how many threads were used, we don't have any information about hyperthreading, what else is running on the computer, clock speeds, memory speeds, etc.

It should be fixed now.

I found the problem. It will be fixed shortly.

GCW tasks are not showing in "Tasks returned in last 24 hours" table.

I think it stopped at about same time as "fast double checking" was enabled for GCW.

I don't see anything obviously wrong. Are you seeing other projects in there? Is it just GCW that's missing? You have 3 GCW tasks that should be showing up in that table, on two hosts.

Edit: Disregard the question.

I'll look into it.
6) Message boards : AP26 - AP27 Search : AP27 Closing??? (Message 143604)
Posted 1 day ago by Profile Michael GoetzProject donor
Has anything come of the discussion whether or not to keep AP-27 running? Or looking for AP-28?


There hasn't been any discussion recently.
7) Message boards : 321 Prime Search : 321 Sieve is being SUSPENDED (Message 143567)
Posted 2 days ago by Profile Michael GoetzProject donor
Is there another sieve that will be opened in the near future?


Not in the immediate future, although this is still under discussion.

We will need to restart the CW sieve at some point. The problem with that, however, is that the GPU software is very old, only works on Nvidia, and will undoubtedly require some work before we can use it again.

There was some discussion last year about sieving ESP/PSP/SoB from 50M to 100M, but we won't need that for a while, and we need to evaluate whether or not (and how) to do P-1 factoring on those numbers. So that's not a simple decision either.

So nothing in the immediate future, but maybe one or two sieves at some point.

Is there a chance we will run out of tasks before the 30 days is up?


If you could run out of tasks before the 30 days were up, what would be the point of giving you a 30 day warning?
9) Message boards : 321 Prime Search : 321 Sieve is being SUSPENDED (Message 143538)
Posted 2 days ago by Profile Michael GoetzProject donor
so is it taken a break or over?


That's just semantics.

We (almost) never shut something down with the expectation that it will start back up again later. If it's worth running, we keep running it.

When we shut something down, it's because there's no need to run it anymore. So, in that sense, you could think of this as permanent. From a user's perspective, you *should* think of it as permanent. If you have a credit goal you want to reach, or a badge, you should get it before October 21st. Don't plan on seeing 321 Sieve ever again.

That being said, sieves are like zombies. Or villains in horror movies. You think they're dead, but they keep coming back for more. What happens is that the underlying project (321-LLR in this case) may eventually run short on candidates. This current sieve is for candidates up to n=50M. I can't even begin to guess when we'll run out of 321 candidates to test, but it will be many years from now. But if PrimeGrid still exists then, we'll have to fire up the 321 sieve once more to sieve from n=50m to n=75M. When we restart a sieve, this is why. We expect this sieving to last for a long, long time. Just not forever.

On October 21st, we will be suspending our 321 Sieve project.

Details and discussion can be found here.
