The sievers should consider using a GPU to sieve, amphoria? I suppose sieve speed should be quite fast with only 128 k's.

I already tried GPU sieving for this drive on a relatively cheap ATI Radeon 5670. It reaches only about 85% of the speed compared to a single cpu core (Q6600) running sr2sieve, and the GPU sieve thereby utilizes a full cpu core too! Not to mention the memory requirement (about 2 GB vs. a few MB using sr2sieve)...

From what I gather, the sr2sieve algorithm does not lend itself nearly as well as ppsieve's to being ported to run on GPUs. At any rate, Ken said that he wasn't planning to undertake such a project in the forseeable future so for now, sr2sieve on CPUs is still the way to go for smaller sieves like this.
