Sorry! I thought I had enough room. There are about 1300 composites from 70 through 72. I didn't mean to crowd you up...

I have 4 cores doing ECM for C70-C80

Not a problem at all. I was thinking you had at least a dozen workers (cores) to my one. I thought I was going to be away for several hours and didn't want to return to find my lonely worker was stepping on your toes.

In hindsight, I should have gone to C79 (and work down).

(I think there is still a BOINC project working in the C80's and above. This should keep them busy for a few days.) :-)

I've been seeing a number of factor already known messages for my C76s so I've upped it to C78 now.

Jeff.

I have done some PRP Certificates and uploadet.

I believe that message is a little misleading. What it really means is the prime factor is already known to the data base. Most likely a divisor of another composite. I think all primes below p19-p20 are known. As bigger factors(primes) are found, it is more unlikely they are known (to the data base).

Too many primes, too little time. :-)

I do have 8 cores across 7 machines and I didn't realize how fast they would fall. There are less than 400 composites left from 70 through 72 digits, so my machines are grabbing some 73s, now.

There must be quite a few workers helping out...

I will be cutting back shortly. As I mentioned before, these machines default to yoyo's script when they aren't otherwise tasked. I am about to retask them...

EdH · 2012-01-07, 03:16

I was seeing 74 digit composites showing up, so I have swapped the machines to something else...

RichD · 2012-01-07, 04:29

My lonely core is also off-line, but I think we did a significant contribution.
Others more than me. :-)

All contributions count! All my 24/7 machines, but two dual cores, are steam-driven P4s. And, one dual core is so ancient, it is 64-bit, but won't run a 64 bit OS. The other is a friend's that I'm stress testing.

Looks like things are starting to clear up. If you ask for a composite above 70 digits, the lowest it is handing out now is C81.

Although I think I found a small bug, if you ask for max digits 80, it still hands out C81 instead of returning nothing.
