New Competition time
Welcome to Summer Paralympics Challenge
To participate in the Challenge, please select only the Extended Sierpinski Problem (LLR) (aka ESP-LLR) project in your PrimeGrid preferences section. The challenge will begin 2 September 2016 18:00 UTC and end 7 September 2016 18:00 UTC. Application builds are available for Linux , Windows and MacIntel 32 bit and 64 bit. Intel CPU's with AVX capabilities will be significantly faster than the ones without (including all AMD CPUs), 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." Please see this post for more details on how you can "stress test" your computer. WU's may take around 6 hours on the fastest/newest computers and more than a day 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.
Highly overclocked Haswell or Skylake (i.e., Intel Core i7, i5, and i3 -4xxx or better) computers running the application will see fastest times. Note that ESP is now running the latest, brand new FMA3 version of LLR which takes full advantage of the new Haswell features. It's faster than the previous LLR app and draws more power and produces more heat. If you have a Haswell or Skylake CPU, especially if it's overclocked or has overclocked memory, and haven't run the new FMA3 LLR before, we strongly suggest running it before the challenge while you are monitoring the temperatures.
Please, please, please make sure your machines are up to the task.
