Hey team,

We are part way thru the Cullen birthday challenge for 2016 at PrimeGrid. There are both Cullen (n2n + 1) and Woodall (n2n - 1)tasks to crunch using LLR. If you have a modern Intel CPU please consider joining me in this team challenge. Currently AMD Users is 14th. The Cullen tasks are a little faster to run than the Woodall tasks. They take about 1 day 20 hours (let's say 2 days) on an Intel Haswell i7 4770S with hyperthreading disabled.

The challenge runs until April 28 18:00 UTC.
