Happy New Year Crunchers! Per the plans we announced last year year, the CUDA 4.2 application is now terminated leaving the CUDA 6.0 and CUDA 6.5 applications in production. Henceforth, the CUDA 6.0 application will become the "compatibility" application, providing support to older systems. It will not receive any feature updates. All new feature releases - new GPU support, performance improvements, etc - will be introduced in the CUDA 6.5 application. Baring any unhappy surprises, CUDA 6.5 will be our build platform throughout 2015 and into 2016. As you can see from our statistics graph http://www.gpugrid.net/graphs/trend-appver.png , showing the fraction of our results produced by each application version, currently some 20% of our results are produced by the CUDA 6.0 application. We'd very much like to reduce that to a minimum, so that as many people as possible are using the better application. To ensure you are getting the CUDA 6.5 application, please ensure that your NVIDIA driver is on branch 343 or higher. Matt

There is a bug in Firmware 1.0 that causes error in pulse counting. The higher is dose rate the greater is an error. Bug was caused by blocking delay that was used in 'beep' procedure. If you have "Radioactive@Home --- 2.60 ---" detector you can upgrade firmware by RS232 connection but if you don't know how to do it - don't do it! Here is an upgrade pack: Please wait a moment... Good luck!

New experiment aimed at solving non-weakened cryptanalysis problem for the Bivium cipher was started. WUs are simpler than ones in previous experiment, so 84 credits are granted for every WU (instead of 130 credits).

Новый эксперимент по неослабленному криптоанализу шифра Bivium был запущен. WU в новом эксперименте проще, чем в предыдущем, поэтому за каждый WU выдаются 84 кредита (вместо 130).
