Re: Digital Signatures

Hmm according to Wikipedia it took 8000 MIPS-years to factor a 512 bit RSA public key which is 2.92 days at 1 trillion instructions/second (Radeon HD 4850 X2). Well there is a chance that it doesn't run nicely on GPUs and it will take a lot longer than 3 days. 512 bit 8000 MIPS-years 463 bit 2000 MI...

Re: about the algorithm used

If it's 64 bit it should start slowing down after interlacing it three times since you need 5 registers to do MD4 or MD5 and you have 16 registers to work with. It might be faster interlacing it four times but it depends on your cache.

Re: Algorithm optimizations (reversing steps)

You forgot that with large lists you'll need to resort every time you reverse. Also with reversing you don't need to re-reverse the whole way you can cheat again. With MD5 you can reverse 2 steps save that point, reverse 7 more steps save that point, and then reverse 7 more steps save that point. Th...

Re: lease time on my High-End GPUs cluster for $$

I'm pretty sure the price at which people will be interested in your cluster it won't be profitable for you. $105 for a recertified 9800 GTX+ or $130 for a GTS 250 (same card different name). Prices are from newegg.com. 560 M/s vs 5 B/s So 14 hours for $10/hr at 5 B/s is 234 trillion passwords (2^47...

Re: about the algorithm used

2x SSE2 just means to interlace (doing your algorithm twice):

algo:
a += b;
b ^= c;
c &= d;
b += d;

"2x" algo interlaced:
a1 += b1;
a2 += b2;

b1 ^= c1;
b2 ^= c2;

c1 &= d1;
c2 &= d2;

b1 += d1;
b2 += d2;

Re: What hash to support next?

DES will probably run faster on a GPU than a CPU per FLOPS. This is because each MP has 8,192 (8000s and 9000s) or 16,384 (GTX 200s) registers vs 16 for a CPU. The best bit slicing implementation is optimized for least amount of instructions (but it might not be the must optimal) this does not assum...

You need to disable SLI for both of them to work in CUDA. Once you do that you'll get 1600 Mhash/s instead of 900 Mhash/s.
