Re: Distributed crypo-network discussion

Well, i wasn't talking about coding the whole WEBSITE in c++, just the server distributing the tasks. 'cause php is too slow for those purposes.
Oh that, and that sending hashes in text instead of in binary form wastes bandwidth.

Re: Distributed crypo-network discussion

Well, considering the fact that I've already put a cracker WITH network support out there;) Sure, the networking code isn't all that pretty, but it works. And it has a fairly low bandwidth cost. Seriously tho, php or any web-scripting language isn't going to cut it for millions of hashes. Might as w...

Re: CUDA supported bruteforcers

Hey, the point isn't a full documentation, the point is enough information to get it up and running. What are the error messages it produces? The application should output some .log files, for both kernels, and the client. Because this might just be caused by your weird setup :P Which, is all the mo...

Re: Cuda/CAL VS OpenCl.

Yes, i did. But last time i checked, with some hacking of the brook compiler, some decent CAL code can be generated by it. There's limitations of course, constants should be stored in registers and passed around, the compiler needs some hacking, and you need to use int4, because shit does not get co...

Cuda/CAL VS OpenCl.

Has anyone benchmarked Cuda and Cal vs opencl yet, for the purpose of hash cracking? I've heard some pretty bad
stuff about it's memory bandwidth on ATI. I'm curious, to see if i should port anything to openCL, or just stick with brook and cuda.

Re: CUDA supported bruteforcers

Hehe, sorry man, but that shit just looked SO suspicious. Been dissasembling and reading your executable for the past hour or so, and it appears to have been written directly in GPU assembler;) Funny, how close the compiler can come to highly optimized assembly, not?

Re: speed of BarsWF / other

Faster for what? Multihash, singlehash, salted? Distributed, single computer? Which algorithm? sha1? mysql5? mssql? mysql232? md5? md4? ntlm? DES? On which architecture. Ati? Nvidia? Amd cpus? intel cpus? On which operating system, vista, xp, linux? What about handheld devices?

Latest version of both the driver and ihashgpu, but this rig runs vista, so the 2nd core is always in 2d mode, with my cracker too. Guess it's just the drivers or something being crap.

Re: CUDA supported bruteforcers

Your cracker, on my box with a single ATI4870x2: 601mhashes/s. Speed of the previous (single hash version) of my cracker: 600mhashes/s Speed of the current (multihash+client/server version): 550mhashes/s, but stable up to 100k hashes. I'd say that its pretty decent, for some 'crappy' BROOK+ app. The...

And a ton more, read th...

Re: PassRape - CUDA/ATI SHA-1/mysql/MSSQL bruter

Getting 600mhashes/s on ATI atm, and 420mhashes/s on a gtx 295. I'm hitting an instruction limit cap here on NVIDIA , so i somehow doubt that i can improve much for the NVIDIA version. I can probably increase the ATI speed significantly by interlacing tho.

Ok, the bug was definitely not in the code itself. ATI somehow generates a TLS directory for the project even tho i do not use the TLS.
