Default 9 Ks

Synopsis
Testing the following 9 Ks from n=700k to 1M:
k=111, 123, 153, 159, 171, 183, 189, 219, and 225

Test files sived to about 9T kindly provided by Masser, further sieved to 13T by Curtis.
k=111 completed to n=1M by Curtis, 2 new primes found.
k=189 completed to 770k by Kosmaj, no primes found.

---------- Original post --------------
Masser released his 9 reserved Ks and kindly sent us remaining candidates in the 700k-1M range. They are already well sieved to about 8T and we can start testing them at once.

Let's decide how to proceed:
a) Sort all cadidates by n and create test files like we do in our drives.
b) Leave a few Ks for people like Cruelty and Curtis who prefer to crunch their own Ks and allow reservation of large blocks, like 700-750k, 700-800k or even 700-1000k and test only the rest in a drive.
Let me know what do you think. The number of candidates is given below.
Code:
 k       Cnt  Per1000n
---------------------
153     20442   68.1 
111     19224   64.1 
189     18068   60.2 
171     16989   56.6 
159     14210   47.4 
123     13589   45.3 
183     11155   37.2 
225      8450   28.2 
219      6801   22.7 
---------------------
Total  128928  429.8
FFT Lengths (on P-4) for n=225 and n=111 respectively:
48k, for n less than 803460 - 828513
56k, for to n less than 933955 - 963183
64k, for other n to 1M

Since we aren't starving for new team work, how about allowing users for 2 or 3 weeks to reserve large blocks/entire k-values, then making a team drive out of remaining unreserved work?

I am currently re-sieving nearly all of my reservations since sr1sieve is so much more efficient, so I may run out of LLR work in a couple weeks while waiting for the sieves to catch up. I'll do a little planning/forecasting on my current work in the next few days, and would like the oportunity to grab one of these k's if it turns out I'll need some LLR work.

Edit: I thought about it a few minutes, and I'd like to tackle k=111 from 700k to 1M.

After a recent post by Masser I decided to provide test files with all Ks sorted by exponent available on-line. I think it's better this way, so that people who want to try them can do so freely without mailing me or anybody else.

They were initially sieved to about 8.9T by Masser, and Curtis sieved them further to 10.1T. He is still sieving the 7 Ks available in test files. k=111 is reserved by Curtis who already reached n=900k and plans to go to 1M. I did k=189 to n=770k and stopped there. k=189 will be added to 7 Ks when/if we reach 770k.

To people who may ask about the priority of this effort: I consider this low priority, lower than the 5th Drive. But these are nice Ks, and test files are small and convenient for beginners.

If you want to reserve any files, please announce so in this thread.
Thanks.
