Congratulations to Mackerel, who had a box turn in our first BOINC Prime this evening. The k is 469949, a relatively light k at about 29,000 k/n pairs removed. However, the test was a missed test on 1st run, highlighting the need for a proper double-check by BOINC.We will release the full k/n pair after it is submitted to PrimePages, but it does weigh in at just over 496,000 digits. Is there another double-check prime out there? Only way to find out is to run LLR and help us hunt down the remaining 66 k's. Thank you to all the participants for helping us bring down the workload, and a special thanks to Mackerel for killing his second k.Manual sieveing DAT file will be released in the morning; the new DAT for BOINC will be released as part of our server switch.
