initialization error

[oj7412]

i've run the multiforcer in terminal on my mac and it seems to work fine as it launches CPU kernel for password length 0, 1, 2, 3, but then i receive the cuda error: initialization error. any suggestions? i'm kinda new at this... thanks!

Len 0-3 are dealt with on the CPU in the 0.6 release.

You don't have CUDA working on your machine.

Reinstall the toolkit, do a custom install, and make sure the CUDA kext is checked - for some reason, this doesn't get installed by default on some machines.

Ugh. I'm getting the same thing with the 3.0.1 beta version of the CUDA driver for mac. Here's the output:

However, deviceQuery does work and shows this:

Test PASSED

At one point I had this working. Then I restarted and it hasn't worked since. I've tried reinstalling both the 2.3 and the 3.0.1 beta drivers, sdk, toolkit etc to no avail.

Any thoughts?

I was able to fix this by doing:

Code: Select all

export PATH=/usr/local/cuda/bin:$PATH
export DYLD_LIBRARY_PATH=/usr/local/cuda/lib:$DYLD_LIBRARY_PATH

I also created ~/.bash_profile and added the above to it in order to (hopefully) have this done automatically upon initializing a shell
