I have released an OpenCL version of pixsieve called pixsievecl. The OpenCL version is about 5.5x faster than the x86-64 version on the laptop which I've tested it on.

"pixsieve" is short for "primes in x" with x being any arbitrary decimal value. For example if you want to sieve terms of the decimal expansion of pi from 900,000 to 1,000,000 digits in length, then this is the program you want to use. It will remove terms will small factors and output a file in DECIMAL format, which can be used as input to pfgw in the hopes of finding a large PRP.

Both versions along with source and 64-bit Windows builds can be found on my website. Although I did not create a makefile, these program should compile and link on OS X and Linux, hopefully out of the box, but if not, with small changes.
