April 20 to April 23 - Shakespeare's Birthday Challenge
Welcome to Shakespeare's Birthday Challenge! William Shakespeare is one of the worlds best known English language wordsmiths in the true sense of the word. He has not only written many plays and poems which are still well known, almost 400 years after his passing, but he has also added a lot of new words to the English language. 1700 words would now have seemed strange bedfellows in the English language, had it not been for him. To honour this linguistic pioneer, PrimeGrid is offering a 3 day challenge on its Proth Prime Search (LLR) application in the run up to the day of his passing. PPS EXTENDED is not part of the challenge! To participate in the Challenge, please select only the Proth Prime Search (LLR) project in your PrimeGrid preferences section. The challenge will begin 20 April 2014 16:16 UTC and end 23 April 2014 16:16 UTC. Application builds are available for Linux , Windows and MacIntel 32 bit and 64 bit. CPU's with AVX capabilities will be significantly faster than the ones without, as this instruction set allows for more computing power. ATTENTION: The primality program LLR is CPU intensive; so, it is vital to have a stable system with good cooling. It does not tolerate "even the slightest of errors." This is doubly true for this challenge. We will be installing the new FMA3 version of LLR for PPS before the challenge starts. If you have a Haswell CPU, you will see increased performance. That means you'll also see increased power consumption and increased temperatures. Please see this post for more details on how you can "stress test" your computer
. WU's will take ~15 minutes on fast/newer computers and 2+ hours on slower/older computers. If your computer is highly overclocked, please consider "stress testing" it. Sieving is an excellent alternative for computers that are not able to LLR.
