[QUOTE=James Heinrich;298848]On the [URL="http://v5www.mersenne.org/report_top_500_P-1/"]P-1 Top 500[/URL], Axon is blazing up the rankings and has found 3193 P-1 factors in the past year (probably less). :surprised[/QUOTE]

Sheesh! I see what you are saying about Axon, but The Judger has already overrun most of the GPU272 heavy hitters in PrimeNet ranking. I'm watching to see how that steep trajectory evens out. It seems that he might blow just about everyone down a notch on GPU272.

[QUOTE=Dubslow;298856]But those aren't actually P-1; there's a thread somewhere here about the low TF work he's doing. This will disappear when PrimeNet's credit assignment system is fixed.[/QUOTE]
Yes, [URL="http://www.mersenneforum.org/showthread.php?t=15690"]see here[/URL].

[QUOTE=chalsall;297617]@petrw1: "This is curious?

Not terribly.

I haven't yet finished the code required to predict P-1 factors found.

It's much more complicated than predicting simple TFing.

But I am amused that someone finally noticed (or, perhaps, noticed and brought it forward).[/QUOTE]
To get the P-1 prediction going, I came up with the following using the data from G272's P-1 stats page at ~0500 UTC today.

The data shows an average across the board of 1 factor per every 21.28 P-1 exponents. Predictions can be made per the following:

[CODE]
ROUNDDOWN( ([I] P-1 done[/I] + [I]factors found[/I] ) / 21.28)
[/CODE]

This does not take into account everyone's actual B1/B2 or E value, only the raw data and a median calcualted off of the results from G272. I know that actual P-1 factor probablity is based on a lot more, but I thought it a good start to see where everyone stands.

[QUOTE=chalsall;298726]Not NFS version 2 nor 3.[/QUOTE]

I now tested all (accessible to me) variations of NFSv3, Samba, cifs, and of course, local file systems. All behave as expected with the O_EXCL | O_CREAT options. (I did not test hard for race conditions, though.)

The mkdir approach may work as well, and it may also be atomically on some systems, but this is not documented (opposed to "open"), so I will not rely on it.

On NFSv2, or when running a Linux kernel before 2.6, the open call may contain a race condition - not sure if anyone has a 64-bit Linux still running a 2.4 kernel ... probably mfakto would not run on that anyway.

So I think I will keep the current implementation, and release 0.11 soon.

Cool!!!

I guess this means I'll have to reciprocate, and deliver my promised work fetching spider.... :smile:

Login
 

Hey chalsall,
I've noticed that login sessions are not shared between the separate language subdomains. While it doesn't really have a practical impact, since in theory a user will choose one language and stick with it, it would be nice for translators or the curious who like to switch back and forth if you could log in the English site and have that transfer to the French site (et cetera).

[QUOTE=Dubslow;299205]I've noticed that login sessions are not shared between the separate language subdomains.[/QUOTE]

No kidding. Do you understand why?

The curious will probably not be accessing password protected areas.

Translators will hopefully understand the reason for the need to log in to password protected areas for each language subdomain.

No new DC assignments?

[QUOTE=bcp19;299416]No new DC assignments?[/QUOTE]

Xyzzy came by, and reserved all the DC TF candidates. I've topped up the supply again.

Milestone: Team "GPU to 72" now #1 for P-1.
 

Hey all.

Just to let you know, the "GPU to 72" team on PrimeNet is now #1 for P-1 work, #1 for TF work, and #3 overall.

Thanks for all the cycles everyone!!! :smile:
