R366 update
 

Whew, the going gets tough.


Here comes 1.5M to 1.6M

Ian and I have completed S461 to n=400K; no primes were found for n=250K-400K; 1k still remains; base released.

Reserving S480 to n=400K for Ian and me.

S 380 complete to n=200K
One prime found:
106*380^182846+1

3 k left.

Results emailed.
base released.

Progress update
 

K4 S332 at 670K
K16 S332 at 600K
K4 S467 at 645K

hi,
please do reserve for me R319

Ian and I have completed S476 to n=400K; no primes were found for n=200K-400K; 1k still remains; base released.

Reserving S 319 to n= 200K.

Status update #001 for S383 and R383
 

SR383 for n=200,001 to n=1,000,000 has been sieved to p=262T.

On December 29th LLR began on 8 instances. Currently the daily production is about 600 results a day and at the end of the range for n=300,000 the daily production will decline to about 400 results a day. All in all this means that running the range n=200,001 to n=300,000 will take between 3½ to 4½ month to complete. Minimum testdepth is currently n=202,000

I expect 2-3 primes for the range n=200,001 to n=300,000 so far 0 has been found.

Take care.

Time taken per test scales with the square of n therefore if n=200K gives you 600 tests/day, n=300K will give:

600 / [(300K/200K)^2] = 267 tests/day

By closer examining my numbers, you are correct and I mistakenly doubled the amount of work the Xeon can do a day. Due to those calculations may 22nd 2019 seems a fair day for completing SR383 to n=300K

Take care
