I'm quite interested in how your core 2 system handles this stuff, both the llr and the sieving... quite interested. Myself, I've been buying amd x2's as the amd handles the sieving pretty decent. Of course not compared to the powerpc chip.

And in regards to the "goals" it's really getting harder and harder to place guesstimates as the technology is rocking right along. Just really depends on how much new tech that people interested in this project purchase.

I have my pc up and running.

I have yet to try sieving, as I had a wee look and P4 is supposedly the best at PRPing. But I will try when my run ends.

I have a Core 2 Duo 6400, 2 2.4Ghz cores. 2Ghz DDR2 800Mhz memory, Sata II harddrive @ 8.9ms response time........and a beverage holder on the front. You push the wee button and the beverage holder slids out and is perfect for a cup of tea.
I am running 2 LLR V3.70 at 7.4ms per iteration. Which I think is pretty good. My 3Ghz P4 at work runs 1 at 9.4ms per iteration. so it is at least 100% increase over that.

will repost my sieving performance when I try it out in a few days. But for other things the Core 2 is very fast.

That would be truly decent!!!!! and also post the range that you ran it on so I can do a comparisson here on my stuff. I'm really curious as I'm holding off on buying anything until I see what the sieving performance is on the duo. I've been sieving here so far, and don't see changing that. :)

I sent you a PM.

But I am getting around 900kp/s over two instances. so 450-465kpp/s on each individually.

Hope this is good, cause I love it!

Brucifer · 2006-09-26, 00:11

yep, that's doing pretty good on combined stuff. :)

why not move the lowest tests from time to time in the llrnet server? those 4 tests are pending forever

they have been reserved by someone have they not.

they are taking a while tho....

I'm generally a big double check and factoring P-1 advocate in SoB.

But for PSP lets not even talk about double checking or P-1 until we reach 5M. I think this is will be a reasonable point to consider P-1 again, it will all depended on sieve depth.

In the mean time lets try to sieve as deep as possible. 400T by the end of the year is IMHO do-able with some work, we will be close regardless. If we can push hard in sieve we won't have to P-1.

hhh · 2006-10-28, 14:58

400T? You meant 300. Soon it's X-mess, and then the end of the year is already there.
Well, anyways, you are right, the sooner we sieve the better. Personally I would stop the SoB-only sieving at Mike's reservation page and sieve even that together with PSP. But that shall not be my consideration. Now, in the wintertime, some top-producers are back, so I am optimistic that sieve remains popular.
With my P4, I find a factor every few hours, and could run 3 tests a day; but the factors save much longer tests, for higher n, so it's a good buissiness to do sieving.

Nope I really mean 400T,

We only have about 40T to go until 300T. We should be able to do that. There are also a few ranges between 300T to 400T that are already complete. I'm hoping we make a big push for 400T and get the majority of it done. I try not to set goals that are easy although this one might be way to hard. We will see where we are Jan 1 07.

I also don't think finding another prime soon is unreasonable.

214519*2^1929114+1
and
222361*2^2854840+1

are pretty far appart even when comparing the previous ones. Hopefully the prime gods will treat us to another in short order rather than making us wait too long.
