About Collatz Conjecture
Collatz is a research project that uses Internet-connected computers to do research in mathematics. You can participate by downloading and running a free program on your computer.
Collatz Conjecture is based in Wood Dale, Illinois. It is a privately managed BOINC project attempting to disprove the Collatz Conjecture. For more information about the Collatz Conjecture, check out the Wikipedia Collatz page. The Collatz Conjecture project makes use of the parity sequence optimization and runs on Linux, Windows, and OS X and can utilize CPUs as well as AMD, nVidia, and Intel graphics cards.

System Requirements
You must have an OpenCL driver installed for your CPU or video card that is recognized by the BOINC client in order to run OpenCL versions of the application. CUDA 4.0 (Linux) or CUDA 5.5 (Windows) is required to run non-OpenCL nVidia applications. AMD CAL/Brook+ is no longer supported due to unfixable bugs in the Brook+ compiler which has been unsupported for at least 5 years. So, AMD GPUs must have OpenCL 1.1 or later capable drivers installed. Both standalone (single core non-OpenCL) CPU and OpenCL (multiple core) CPU applications exist. Set your preferences to omit either, neither, or both. The OS X AMD applications may not work due to bugs in the AMD OpenCL driver for OS X. Multiple requests for fixes to both Apple and AMD have evidently been for naught as the only way to run it without errors is to use no optimization which runs slower than a CPU.
BOINC 5.0 or later for CPU tasks
BOINC 7.0.28 or later for OpenCL GPU tasks on AMD, nVidia, or Intel GPUs
BOINC 7.2.21 or later for OpenCL CPU tasks
For OpenCL CPU Processing:
OS X 10.7 or later (no additional OpenCL driver necessary)
For Linux and Windows, either the Intel or AMD OpenCL driver is required.
For Windows, the most recent Visual C++ runtime 2012 or later - these can be downloaded from microsoft or searched for. Alternatively download them from our server here .
For GPU processing:
AMD Radeon HD 5000 or later graphics card with OpenCL 1.1 support
Intel HD 2500 or later embedded GPU with Intel OpenCL driver
nVidia 8400 GS or later graphics card with recent nVidia driver
OpenCL Drivers are available from:
AMD Video Driver - Caution: The HD 4770 and 48xx GPUs require the Legacy AMD Catalyst driver which is NOT the same as the current AMD Catalyst driver.
nVidia Video Driver
Intel OpenCL SDK and/or Runtime - requires Intel Core processor with SSE4.1
Note: If using multiple OpenCL devices from multiple vendors (e.g. nVidia video card and Intel CPU), it is recommended that the driver with the lowest OpenCL support level (1.0, 1.1, 1.2) be installed first. If possible, install OpenCL drivers that all support the same OpenCL version.

The math
I think this is fool-proof but could you just try it for me please? • There are 10 types of people in the world; those who understand binary, and those who don’t
