hello there,
ive been using iceecc for years and love it!!

but always wanting the next versions get better and faster.. so these days new fashion; using gpu for this kinda works can help iceecc many times. why dont u do it? new graphic processors are being used in similar things like pasword generating, i saw even a par2 program beta version for reed solomon algoritm.

gpu powered iceecc would be awesome pls consider this.

have a good day, keep up the good work...

There are 3 problems with GPU solution:

1. Internal GPU operations are fast. However data transfer GPU<>CPU not so fast. As result instead of speed improvements can be speed degradation.

2. Internal GPU memory very fast. However it's use less reliable RAM chips than system RAM. Some memory failure during rendering graphics usually invisible for user. But even the single memory failure of one bit during ICE ECC computation will destroy all data.

3. There are a lot of different, incompatible API, for working with GPU. CUDA exist for all platforms. But CUDA support only for NVidia. DirectCompute support both NVidia and ATI. But it's available only in Windows 7. But it's not all. There are less popular API: OpenCL, GPGPU. Each API has its own subtleties and complexity. Tough choices.
