That's too bad, because some people may have trouble viewing it at all. Some browsers stop if a webpage has not finished loading within 60 seconds; and the status of the highest exponent is always the last to load. So some people might not be able to view it at all.

Anyway, I was able to view it. At 14:17 UTC on Jan. 18, 2008, you were at iteration 3,446,919.

Interestingly, there are two other LL tests going on that are well above the main leading edge. S709129 is testing M59,999,999 and andreasbomke is testing M59,289,959. The next highest after that is less than M42,000,000.

Unless it is a laptop, you don´t have to worry about that. Trust me, I have been crunching for GIMPS for 6 years, and have never damaged a machine, even though I have had them running 24/7. I am still using on a daily basis an Athlon XP1800 that is running the client from the very first day.
If your concern is the electricity bill, that´s another story. I have lately reduced the crunching effort for that reason.

I agree....I have been running my P4 2.4 Ghz Desktop non-stop (unless there is a power failure of I have to reboot for a Windows patch) on GIMPS for over 4 years without any sign of wear and tear.

As of 20:20 UTC, Jan. 27, 2008, Starqwest was at iteration 4,141,425. That comes out to 694,506 iterations in 13,323 minutes, a per iteration time of 1.151s. At that rate, it will take him until 14:36 UTC on Feb. 7, 2017 to finish the 100 million digit test.

StarQwest · 2008-01-28, 13:01

I am currently running the test about 15 hours a day just to keep working on it, although I will likely get a new computer this summer which is much, much faster. I hope to finish by 2011 at the latest. Just out of curiosity, how much faster is the Quad-Core Processor than the Pentium D when running version 25?

S485122 · 2008-01-28, 20:43

It depends on which QuadCore and which Pentium D, but clock of clock, on a single core a core2 with adequate memory is at least 40 % quicker. (for M333000000 a core2 3GHz will take less than 5 years and a P4 3GHz 7 years.)

AFAIK, the latest version of the Prime95 client has gone multithreaded, which allows you to run a single exponent in several cores. If you get a 4-core 45 nm Penryn, I think you will run the test MUUUCH faster than on a Pentium D, even running the Penryn at stock speed. Add the fact that Penryns are excellent overclockers, and you´ll end up with a top notch cruncher.
Or you might as well wait for Nehalem to come out...

Just wanted to say that you might want to inform the 100 Million digit prefactor project of your intentions if you haven't already.

Also, if you are seriously considering getting a new CPU, wait just a little more until Intel releases some 45nm octocores, one of those will really move your test along.

Does Intel indeed plan to release octocores in the near future?

lavalamp · 2008-03-06, 07:50

Sadly, now I check again, it seems that 8 core Nehalems won't be here until 2009, however there should be some native quad core (far better then double dual core design) Nehalems this year.

Nehalem!!!

Does 4 cores / 8 threads for Bloomfield and Lynnfield processors mean, that these are hyperthreaded Quad-cores?
