Here you'll find my programs related to prime numbers and, often, distributed computing.

• PSieve - A group of sieving programs for near-multiples of powers of 2 (K*2^N+ and/or - 1).  All are based on Geoffrey Reynolds' GPL-ed TPSieve source code.
• PPSieve (Source) - Sieves for factors of numbers of the form K*2^N+ or - 1.  Independent of K's, but good for many N's too.  Used by PrimeGrid for their PPSE sieve. (Windows build instructions)
• PPSieve CUDA (Source, on the redc branch) - a version for use with nVIDIA GPUs.
  
• PPSieve OpenCL (Source, on the redcl branch) - a version for use with ATI/AMD GPUs.
• TPSieve - The initial result of my collaboration with Geoff Reynolds; similar to PPSieve, but for finding twin primes of the same form.
• TPSieve CUDA - a version for use with nVIDIA GPUs, built from the PPSieve CUDA source.
• CWPSieve (Source, on the cw branch) - Sieves for Cullen and Woodall numbers on nVIDIA GPUs.
• NSieve64 - My initial attempt to make a 64-bit Proth prime sieve faster than NewPGen.  Generally 15-33% faster for a single N!
• A Windows build of Shoichiro Yamada et al's GeneferCUDA.
  
• SBQueue - My old Java program to store work and results for Seventeen or Bust.  Obsolete since their new client was released in March 2009.
• The ECCp-109 distributed computing project.
