Programming on ATI, whats the lowest level language?

I'm a little confused, if someone wants to program on ATI graphics cards what is the lowest level language to use and what tools to do it? Is opencl if you wish to add cpu computation to the program? I heard brook isnt used anymore, so is it ATI stream? Does visual studio support ATI stream like it ...

How will Intel Sandybridge help with GPU programming?

As the Sandybridge intels have some sort of on-die GPU, how will this compare with a proper graphics card for key-cracking? The i7 2600k has 12 'EUs' http://en.wikipedia.org/wiki/Sandy_Bridge_(microarchitecture)#Mainstream_.2F_High-End http://en.wikipedia.org/wiki/Execution_unit im just wondring how...

Re: 33.1 billion hash/sec

Mysql323 is kind of low on my priority list because it is rarely requested. I have also heard (IIRC) of performance levels of trillions of passwords per second with CPU-based mysql323 brute forcers, so this symbolic barrier has already been broken :-) What is this method you speak of? I tried googl...

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. Ah ok thanks for this. I (wrongly) made the assumption that each new ATI GPU would be better than the previous, but obviousl...

Re: 33.1 billion hash/sec

8xHD 6970 should do about 38.6 Bhash/sec under whitepixel v2. Possibly up to ~41 Bhash/sec with some more code optimization ideas I may have... Linux drivers support at least 8 GPUs. Windows drivers are limited to 4 it seems. CPU speed is irrelevant for whitepixel. It does not use the CPU at all. C...

Re: 28.6 billion hash/sec

I released whitepixel v2. The nice surprise is... support for the BFI_INT instruction which allows implementing the MD5 subfunctions F() and G() in 1 clock cycle. My 4x5970 setup now reaches 33.1 billion passwords per second . http://blog.zorinaq.com/?e=43 http://whitepixel.zorinaq.com/example.png ...

Re: 28.6 billion hash/sec

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: 28.6 billion hash/sec

Are we suggesting, if someone had 8x Radeon 6790 cards we could get roughly 80billion/second on this Linux software?

I'm presuming 8x 6790s would be better than 8x GTX 580s ?

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). haha, yes thats what i was g...

Would this system be brute-force-uncrackable?

If you had a target system where the password/hash required changed every minute, using an algorithm?

Unless the brute-force system could traverse every single combination of hashes within the period of which the target system rotates hashes, surely it would be uncrackable?

Re: Qestion

This has nothing to do with GPUs or CPUs this is the big picture. He's saying if you have 5000 MD5s that it is faster to generate an MD5 and check it against a list of MD5s you're trying to crack than generate an MD5 and check it against the first MD5 you're trying to crack then regenerate the same...

Re: Qestion

Just because it can be done, doesn't mean it's the smart way to do it. Would you want to crack 5000 md5 hashes one at a time or all at once.. If the keyspace you were searching took on average 1 min to finish per hash it would take you 3.4 days to finish 5000 hashes in single hash mode. Even if it ...

OpenCL changes the dev environment a bit. However, atom of oclhashcat claims the nVidia OpenCL runtime is massively buggy. What type of work are you doing?

Sorry for the delay in reply. Blazer: It runs off of two 1200watt power supplies.
