I'm not saying this is a good way to do it

but:

On some machines I give them a particular k value (starting from the bottom of the range I am testing) & then I can leave them to get on with it with little intervention.

Other machines I take a k range (starting from the top of the range) and sort them by size & give the machines a couple of weeks work to do. This is a bit more labour intensive so I'm now wondering why I do this.

The ones I am waiting for are in the first category where a slow machine or large file is allocated to a machine & is just going to take a while to finish. I wondered about taking them off & finishing them more quickly but I can't really be bothered as they will finish soon enough anyway. I guess that's the point of the second method so you don't get 1 machine stuck with weeks of work when the others have finished.

Original project goal #6 has been accomplished!

gd_barnes · 2009-06-28, 05:04

OH YEAH!!

Thank you to all of our dedicated searchers. And to think this was done while also running double-checks and filling in all non-top-5000 ranges as we went along.

I couldn't ask for a finer group of technically competent and detailed-oriented individuals to help make this come true! I know someone had to tell me how to run my computers. lol

Let's maintain that lead as long as we can! :-)

Next target: To be the #1 non-BOINC project on top-5000 score! An upcoming drive later this year for k=300-400/n=1M-2M will help with that.

I have migrated my web pages from googlepages to the noprimeleftbehind site. This involved changing links to posted sieved files and downloadable programs here at NPLB. Let me know if you have any problems with them.

On another note, I will be out of town from later today (July 11th) to July 22nd. I'll be on but not as much as I would normally. Things have been quiet here but we've been crunching along and finding plenty of primes so I think Max, Ian, and Karsten will hold down the fort if I'm not on as much.

Gary

gd_barnes · 2009-07-31, 01:15

NPLB now owns 20% of the top 5000. To the best of my knowledge, we are the first project to ever accomplish such a feat. Attached is the screen shot. The feat was accomplished at about 19:50 CDT on Jul. 30th. (0:50 GMT on Jul. 31st)

It was a serious effort to keep pounding them out even as our myriad of lower primes were dropping off at a rapid pace.

Congrats to all for a job well done!

kar_bon · 2009-07-31, 06:21

... and when i'm right (i'll see the next hour) we're jumping up on place 6 for the Project scoring with my latest prime for 327*2^949109-1!

Done! the 6th place in terms of score at Top5000 reached! see "Historicals and Milestones"

AMDave · 2009-08-01, 10:53

Awesome results kar_bon.

Kar_bon now owns the top 5 and 7 of the top 10.

The rest of us really need to lift our game ;)

kar_bon: so 5 to go for the Top 10 for me!

Two years ago, TPS and Primegrid had 2000 primes on the top 5000 list. Splitting the credit would give each project 1000 primes.

Congrats to projects Twin Prime Search and PrimeGrid for attaining
1000 primes between them (with a few pending submission
verifications.) I have not seen this sort of thing since Kimmo
Herranen's announcement:

"At 3rd of June 1999 , I achieved to have 1000 primes at top 5000."

gd_barnes · 2009-08-02, 19:22

Ah well. Burst our bubble a little. lol Regardless, a great achievement for all 3 projects.

That's amazing that a single individual had 1000 primes at one time. That should be very difficult in today's day and age with highly efficiently run and automated prime search projects.

Thanks for setting the record straight.

We are no longer #1

PG took over and we fell below our 1000 primes on the list.
