GJSieve v2.0.3 x64 27 September 2012 by Jaska (NullCoding) http://sourceforge.net/projects/gjsieve http://ncprime.blogspot.com ///////////////////////////////////////// About: GJSieve is a basic calculator and primality tester for Proth numbers. A Proth number is any positive integer of the form k * 2^n +1 where k is a positive odd integer and n is a positive integer such that 2^n is greater than k. This is version 2.0.3. It is identical to version 2.0.2 in terms of functionality, but this is fully 64-bit (meaning it will NOT run on 32-bit systems or anything earlier than XP). I have noticed a speed increase and I hope you do as well! The best way to learn about how the program works is to simply use it. ///////////////////////////////////////// Changes: - 64-bit means no more CPU / RAM display as inline assembly code is no longer supported. ///////////////////////////////////////// How to use: 1. Input k and n in their respective boxes. 2. Click Calculate... 3. Select a testing method using the radio buttons near the top - BFTD or SPAT. 4. Press TEST! 5. Click Save As Formula if you wish to save your results. The file is automatically placed in a GJSieve 1.9.0 Results folder created in your Documents directory. 6. Click Clear to clear the boxes and reset for another test. ///////////////////////////////////////// Notes: - Reverse mode IS verbose mode, but with 6 threads instead of 3. It accomplishes exactly the same thing. Sometimes, reverse mode finds factors you'd ordinarily have to wait quite long for the other threads to find. - The threads all run in the same process, unfortunately. This means that the speed increase is minimal compared to, say, 3 to 6 separate processes. - BFTD in Verbose mode (NOT Reverse) is still the BEST way to factor the number. It also takes the most time. ///////////////////////////////////////// Known Issues: - Re-sizing the window is possible, but ugly and pointless. - Color choosing is a bit messed up, but works okay.
