How many... ?
 
Out of curiosity, does anybody keep track of (or is there a way to find out) how many CPUs of a given description are participating in GIMPS at any given time?

I'd be interested in knowing things such as (but not only) how many quad-core machines are donating cycles (and how much); or at least how many =/> 3.0GHz cores are participating and how many GHz-days they are contributing to the total, percentage-wise.

Figured the PrimeNet subforum would be a logical place to ask, but I'm willing to go to another section if this is not the right place.

Mercy beaucups.

(I hope you know that's not how it's spelled. It's spelled buckets!)

Unless you ask George to do a database query (which may or may not actually have the info requested), your best bet is to look at [url]http://www.mersenne.org/primenet/[/url] . I generally consider the number of computers that reported in the last month to be a fairly accurate estimate of total throughput, i.e. ~27.000 comps. (Note that this is a small fraction (understatement) of the ~550,000 comps registered.)

Prime95 posted stats on what type of CPU a few years ago. It might have just been from v4 of primenet though. Pretty certain it only went upto Pentium 4s as well although it might have been improved since.

Dubslow,

Thanks for the link. Unfortunately, that page provides only aggregate figures. I'd like to know the percentage of teraflops contributed by, say, CPU cores running at between 2.0 and 2.999 GHz. Given the wealth of cool and esoteric data available for this project, I'd be surprised if nobody is keeping track of this sort of thing.

Maybe asking George is the best way to go.

Oh man, so they used to do it but no longer?

Do you remember how to get to that page?

Let me elaborate: That information is (apparently) stored in PrimeNet's large database, and is accessible. Problem: Accessible only by Messrs Woltman and Kurowski, the latter of whom I've never seen in my relatively short tenure here.

There was a known problem when V5 started of computers getting duplicated (hence George adding the option to merge CPUs)
[url]http://www.mersenne.org/cpus/[/url]

[QUOTE]The server may erroneously create a duplicate entry for one of your computers. This isn't harmful, but can result in some confusion having two entries for the same computer in the table above. This "cloning" can occur if you upgrade a computer's CPU, upgrade or re-install Windows, or run into a program bug. You can merge the two entries by checking two computers above, checking the "I am sure" box, and clicking the merge button. WARNING: This cannot be undone.[/QUOTE]

Whether this has been fixed or not the bug has been around long enough to be sure the current count of almost 552,000 is overstated. I personally probably had to merge at least 15 or 20 duplicated since then and I only have about a dozen PCs in my farm.

my statistics tell me I have 14 computers used for the TF LL and P-1 I've done unless I changed my IP a lot I don't see how that is ( if I remember correct it's only been 2 computers)

It's the GUID that identifies it, not the IP (most residential IPs don't even use static IPs).
Apparently upgrading Windows or whatever these all are change the GUID. Or something.

Also changing or adding a video card. I decided to add my 6770 to my 2500 since it has room for 3 and got a mismatch error when I restarted.
