The B5SPBS24 Rally

The Base-5-Sierpinski-Prime-Before-September-24th (B5SPBS24) Rally

If we do not find a Base 5 Sierpinski Prime before Sept. 24th, we will have gone a complete year without finding a prime from that queue! We are a (fairly) young project and interest here seems to wax and wane regularly, but we should be able to churn out at least one prime a year on each queue at this stage of the project. So, I kindly request all of our LLRNET testers to move their machines to the Sierpinski queue:

-- Server location and port for Sierpinski Server
server = "www.sr5.psp-project.de"
port = 12920

For any interested manual testers, I made some Sierpinski reservation files available in the LLR-pick a range thread.

Anyone else interested in helping, feel free to join us in this temporary surge!

I'll put one fast core on this server shortly (as soon as I finish my <1hr worth of work I've currently got on that core).

Uploaded the files for manual reservations. See http://mersenneforum.org/showthread.php?t=10451

We have three weeks to go with this rally. We could really use some machines on our Sierpinski queue.

Thanks in advance for any help you can provide.

I've kept one core of a Core 2 Duo E4500 (2.2Ghz) on the Sierp. server steadily since the beginning of this rally, and plan to keep at least that much firepower there at least until the September 24th deadline (or maybe a bit earlier if a prime is found, we'll see). Haven't found a prime yet, though I'm still holding out--it would be my biggest overall prime yet if I was to find one.

Two weeks to go...

Has a prime still not been found? I think I'll run this for 48 hours or so.

Hi
How long would one candidate take on one Core2 core at 3GHz?
Could you please post a link to a thread that explains what you are trying to achieve here. (I'm clueless but happy. lol.

)

You could run a quick timing on the sort of numbers it gives out, like these from one of my core's work files:

Code:

1000000000:P:0:5:257
152588 311811
29914 311816

My Athlon X2 2.5 GHz takes ~2.5 hours for each per core, but Intels are much faster than AMDs, unless I'm mistaken because of something like PRP tests running faster than LLR tests (not sure, I haven't really done much PRP work), and there's the GHz difference.
BTW you'll need the LLRnet that can run PRP tests, and the link from this forum is down. I'm using the one linked from http://www.mersenneforum.org/showthread.php?t=9911.
Can't really help you with the second question, I'm almost just as new here as you, but I think they're eliminating candidates for base 5 Sierp and Riesel numbers by finding base 5 Sierp and Riesel primes.

2000 secs at n=280k.

BTW, I recommend to use the standard client and not llrnet. You can go here to reserve some ranges.
