Re: Got shiny new LGA2011 rig today :-D

You can easily test it by compiling an AVX only version. AVX uses the same intrinsic functions as SSE2 and stuff. So you just have to tell the compiler to use AVX instructions.

For the Intel compiler:
icl /QxAVX
icc -xAVX

MS Visual Studio compiler flag:
/arch:AVX

GCC compiler flag:
-mavx

So does this mean you're going to add AVX support?

Re: How to make barsWF use only 50% of cpu?

Windows task manager. In the processes tab right click on the process for BarsWF and click set affinity then select which cores it can run on. The CPU version is really old 0.8. The source code from http://3.14.by/forum/viewtopic.php?f=8&t=1333 says has a version of 0.c (12). You can download the CU...

Re: CUDA low speed

With the Core i7 you might want to try 8 CPU threads since it has hyper threading. 25 * 2.93 / 2.4 = 30.5. Nvidia cards have a lower clock-core vs ATI but Nvidia cards are more efficient per clock-core. 5570 is 650 MHz * 400 cores = 260,000 Mclock-cores 460 is 1300 MHz * 336 cores = 436,800 Mclock-c...

Re: 33.1 billion hash/sec

The CPU code that does over a trillion passwords per second for MySQL323 has divergent code so it will be hard to get nice performance with GPUs or SSE2. Also it only works for a single hash at a time so multiple hashes will slow it down until it gets to a point where it makes more sense to just gen...

Re: 33.1 billion hash/sec

HD5970 has two GPUs in it.

4 HD5970 * 725 MHz * 1600 cores * 2 GPUs = 9,280,000
vs
8 HD6970 * 880 MHz * 1536 cores = 10,813,440

8 HD6970 is 1.1652 times faster than 4 HD5970.

Re: How to use barswf with $1$ hashes ?

BarsWF does work with md5(unix) hashes just plain unslated md5 hashes. Interesting it appears that he's only checking to see if it is 32 characters long. This is a bug you should only be able to input characters that are hex ("012345789abcdef" or "0123456789ABCDEF"). md5("david") is 172522ec1028ab78...

I'm going to guess you mean Radeon 6970 not Radeon 6790. A Radeon 6970 58.3% the speed of a Radeon 5970 (assuming the stats of 880 MHz and 1536 cores are correct). So 8 Radeon 6970 would give you 33.3 billion/second (assuming they can do the same amount of work per clock-core). I assume the 6970 is...

Re: Would this system be brute-force-uncrackable?

My point is that if the required hash keeps changing, then brute forcing is only worth while if you can complete all the permutations in less time than the hash is changed? Wrong. It's a probability game let's say you can only check 10% of the key space before it changes. You'll have to guess 65.92...

Re: Would this system be brute-force-uncrackable?

Are you talking about this?
http://en.wikipedia.org/wiki/SecurID

And no it is not uncrackable. Well something that has a 256 bit key I'd say is uncrackable (well depending on the algorithm such as a 256 bit RSA private key is crackable in like a hour on a new computer).

I'm pretty sure ighashgpu is less than 23% faster than BarsWF Brook version. So 9.87 / 1.23 = 8.02 Billion PWs/sec hey it's a tie.
