1) Message boards : Macintosh : Computation error: "Unspecified driver error" after many hours of working fine (Message 13209)
Posted 2207 days ago by OzgurDusunceli
Here is a CUDA task that errored out after many hours of work with the Collatz v2.06 application:
http://boinc.thesonntags.com/collatz/result.php?resultid=103276065

It seems to have happened in the middle of the night, when nobody's using the computer. Has anyone else seen this kind of error? Is there anything that can be done about such problems? Should I reinstall my CUDA drivers once more and hope it doesn't happen again?

This was on a MacBook Pro (with NVIDIA 9400M & 9600M GT GPUs) on Mac OSX 10.7.2. Let me know if you need more info.

Cheers!

To follow up on this: I got one task completed fine with the app_info I posted here. Though another task errored out (unspecified driver error), but that shall be the topic of another forum thread.

Would you mind sharing your app info if it works?

Sorry, here you go :)

(You can change the flops value to whatever is realistic for your GPU).

And if anyone couldn't find the optimized applications page, I got the 2.06 collatz application for Mac OSX from here:

I downloaded collatz_2.06_x86_64-apple-darwin__cuda32 and managed to get it to run by creating a proper app_info.xml. That one seems to be running tasks fine so far. I'll give an update once a task gets completed.

Cheers!

Hi!

I'm new to Collatz, and trying to run some CUDA tasks, but I'm getting computation errors with all my Collatz tasks (both collatz and mini_collatz v2.02 (cuda) applications).

The error is always this: "cudaSafeCallNoSync() Runtime API error in file <collatz.cu>, line 448 : invalid argument".

What should I do to fix this?

I have both CUDA driver (4.0.50) and CUDA toolkit (4.0.17) installed on Mac OSX 10.7.2. My GPUs are: NVIDIA GeForce 9400M (256 MB) and NVIDIA GeForce 9600M GT (512 MB).

Executables: collatz_2.02_x86_64-apple-darwin__cuda and mini_collatz_2.02_x86_64-apple-darwin__cuda.

e.g. task:
http://boinc.thesonntags.com/collatz/result.php?resultid=103274731

The whole error message is:
"process exited with code 255 (0xff, -1)
Running Collatz Conjecture (3x+1) MAC OSX CUDA GPU application v2.02
based on version 1.2 by Gipsel
instructed by BOINC client to use device 1

No checkpoint data found.
cudaSafeCallNoSync() Runtime API error in file <collatz.cu>, line 448 : invalid argument."

Cheers!
