RPS 7th Drive: 21 HighWeight Ks
We are starting a new drive, featuring the following 21 highweight Ks:
Batch 1: 2235, 2265, 2295, 2325, 2355, 2415, 2445, 2505, 2547, 2565 [10 Ks] Batch 2: 2655, 2685, 2715, 2745, 2775, 2835, 2865, 2895, 2925, 2955, 2985 [11 Ks] The idea is to try again some highweight Ks, and to make available candidates for small but reportable primes, good for newcomers and people with slow machines. The test files sieved to 5T in the 350600k interval kindly provided by Beyond. Found primes are given in post #2 below. We are starting at 360k, using 1k and 2k test files given below. On my 2.66GHz quad P4, one test at 365k takes about 140 sec, meaning about 52 hours to test a 2k file. [All Ks have FFT jumps to 28k in the 365367k range.] Smaller and larger test files, and those in the 350360k range available on request. Update (Aug. 23, 2009): Continuing from n=600k to n=1M with 20 Ks. k=2865 stopped at n=600k and released. Sieving by Beyond, Thomas, amphoria and Kosmaj. Update (Sep. 13, 2011): Extending the Drive past n=1M! Happy hunting! Status Code:
