OpenCL Beta for Linux!

Postby Bitweasil » Wed Sep 21, 2011 12:00 am

Attached.

Please test out.

NOTE: The defaults SUCK right now for thread/block count.

If you're on ATI, you'll want to use:

--threads 256 --blocks 256 -m 100 --amd

Seriously. Otherwise performance blows.

Otherwise, the same as the other gen tools.

Right now, it is MD5/NTLM *ONLY* - no SHA1 (yet).

Needs an OpenCL runtime and libnuma (apparently a requirement for the Intel OpenCL runtime...)

It should work on CPUs as well - just don't use "--amd" and pass something like "--threads 8 --blocks 1" or so. I think it works with both the AMD and Intel OpenCL runtimes.

I expect plenty of bugs/glitches... but I think it's correct.

Also, it should generate byte for byte identical files to the CUDA version. If it does not (with the same --seed), it IS A BUG. Please report it!

Will test it this night. Hope it work with my cards :D

Another question, is the source public ?

Ah, source will be up soon. Forgot to throw that into SVN.

Windows version, yeah, will be coming. Don't know how to build an OpenCL project on Windows yet. :)

This is the error i get when I try to run GRTCLGen with the command line above

My configuration:
1xATI Radeon HD 4850
Kubuntu Linux 64 bit
AMD APP SDK 2.5 installed and working (the oclHashcat* tools works fine)
ATI Catalyst suite 11.8 installed.

My .bashrc:
Code: Select all
export AMDAPPSDKROOT="/opt/AMDAPP"
export LD_LIBRARY_PATH=$AMDAPPSDKROOT/lib/x86:$AMDAPPSDKROOT/lib/x86_64:$LD_LIBRARY_PATH
export ATISTREAMSDKROOT=$AMDAPPSDKROOT


Hope there are enough details :)

Oh, and all your mirrors and torrents for the RTs are broken (at least to me)

P.s.: Where is the SVN for your programs?

Alright, I'll take a look and see if I can replicate it.

SVN... yeah, need to push the code into the sourceforge SVN :) I'm going to try and do that today.

Thanks for the Windows links, I will see what I can do!

There seems to be a problem with MD5 generation

Code: Select all
./GRTCLGen -h MD5 -c charsets/charsetall -l 7 -i 0 --chainlength=100000 --threads 256 --blocks 256 -m 100 --amd

-- snip ---

Binary size: 183960
Doing BFI_INT magic...
Performing BFI_INT patch for 65 ops...
Found return instr that returns non-void in Function of void return type!
  ret <4 x i32> %4
voidBroken module found, compilation aborted!
Aborted


Using the same command, just "-h NTLM", works fine.

I may be missing something here, but using
Code: Select all
./GRTCLGen -h NTLM -c charsets/charsetall -l 7 -i 0 --chainlength=100000 --threads 256 --blocks 256 -m 100 --amd


generates a single file

Code: Select all
-rw-r--r-- 1 panda panda  85M 2011-09-27 22:35 NTLM-len7-idx0-chr95-cl100000-sd117280647-0-v2.part


Is that right?

FYI, generation speed on a 5870 is:

Code: Select all
Total execution rate: 3798.94 M/s

kk, I will take a look. OpenCL is *such* a pain in the rear compared to CUDA...

Yeah, that just generates one table of the maximum size the card RAM will support. You need to pass the "--numtables" option to generate a ton of tables...

I need to write up a full tutorial on the tools. I'll try for that this weekend while I get a motorcycle worked on.

Ok, looks like I am generating, using this command

Code: Select all
./GRTCLGen -h NTLM -c charsets/charsetall -l 7 --chainlength 200000 -i 0 --numtables 4 --threads 256 --blocks 256 -m 100 --amd -d 0


I will let it run to completion then test.

I have been trying to figure out the optimal settings to use, using this:

http://www.tobtu.com/rtcalc.php?reductionFunc=grt&cpTables=10&cpSpeed=3800.0&cpFileFormat=GRT&loweralpha&upperalpha&numeric&symbol14&symbol18&space&pwMinLen=7&pwMaxLen=7&cpTotalSuccessRate=99.999999&cpChainLength=200000&cpPerfectRT&cpgrtIndex=32

which should be exactly the same as the settings you used to generate the length 7 NTLM tables available for download. However, I see that the estimated size is 195GB whereas yours are only 54GB. What am I missing?
