Some info about OpenCL performance

[BarsMonster]

Just wanted to let you know my results of porting existing CUDA application to OpenCL ([url=“World Fastest MD5 cracker BarsWF : Svarichevsky Mikhail”]http://3.14.by/en/md5[/url]).

Here are the numbers:
CUDA: 26.73 MHash/sec
OpenCL: 25.38 MHash/sec (some stuff is hardcoded, so actually it should be a tiny bit slower)

So, I’ve decided to stay with CUDA for few months, looking forward to see same performance as CUDA & working cross-platform execution.

I have two questions:

• What’s your GPU precisely?

• Did you use GPU-only or are using CPU too (in Mac OS X it’s default to aggregate them :-) )

thanks!

This is a very intresting topic. I’ve not be able to find any good information regarding this issue.

Im currently into a project with converting hash algorithms for GPGPU acceleration and im very intrested in your results.
