Individual-k reservations k=300-400 n=600K-1M

[gd_barnes]

With drive 3 virtually complete to n=480K and with several k's previously searched from n=480K-600K, we are releasing 9 additional k's for individual reservations for k=300-400 for n=600K-1M. They are:

303
305
309
313
315
317
319
321
325


I will shortly update post 1 in this thread to include these k's and k/n pair counts.

In the mean time, just this morning, I got a PM from Cruelty that he would like to reserve k=311, 317, and 337.

Carlos, sorry about that. With these additional k's available, would you like to choose a different k? Since it looks like you'd like a low-weight k, the lowest-weight k remaining of all of the k's is k=373.

If that's still a little too much work for you, feel free to reserve it for n=600K-800K or n=600-900K, etc.


Thanks,
Gary

Send me 373 instead...

The file has been sent.

Thanks and welcome back to the effort!

I will also want to reserve 307 and 331 but I will only start testing them within 7 days. I pretend to dedicate two cores to each.

[gd_barnes]

k=301 complete to n=732.5K on 2 cores.

k=323 complete to n=727.2K on 1 core.

No primes yet.

This is now going too slow so I've added another core to each for n-ranges in the 800Ks.

Karsten, with your next update, please reflect all of these individual reservations on the 300<k<2000 page above the NPLB reservation like you've done with Curtis's reservations and update any searched range posted here. Within 2-3 weeks, drive 3 will have all ranges completed to n=480K so at that time, all of the k's here will have technically been contiguously searched to n=600K. On my k's they've already been fully searched to n=600K so the ranges that I reported here are, in effect, fully completed with no gaps.


Thanks,
Gary

With only ~5000 candidates each, I'm sure you could do 1 core each and complete them relatively quickly.

I'll PM the files to you shortly.

I really prefer to have two cores per number so I can be able to test lower and higher ranges at the same time, and of course, to be able to finish them as quick as possible.

Progress: k=373 done to 640,000, no primes.

Gary,

Just to let you know I started k=307 on two cores where one core will do from 600k to 850k and the other one from 850k to 1M.
k=331 will also be tested in two cores, same strategy as 307, but still in pause. First core will start soon and the second one will follow as soon as it finishes some work, hope today.

Meanwhile, k=337 is at ~671k.

Note, K is Kelvin for temperature, it's k (lowercase, SI prefix, means kilo).

This one was fast: 331*2^600339-1 is prime!

Thanks for the update. Everything sounds good.

I was aware of the strange use of 'K' but I use 'K' to differenciate between 'k' the multiplier and 'K' that I use to mean kilo in our prime # forms. Someone had commented that it looked funny to see one of my twin pages titles:

"Twins must be larger than k*2^10k-1 to appear on this page."

The above is technically mathematically incorrect. That's when I decided it was time to change.

There are too many k's, oh I mean K's floating around! lol
