How do y deal with the 'watchdog timer' ?

Postby zhangft » Sun May 09, 2010 11:51 pm

Using the cublas,if the matrix size is too large I always get the error:"the launch timed out and was terminated."
But I notice that CULA does not have this problem.
How do y make it? Can y share the experience pls?
thx!

That's pretty common with CUBLAS and it's something we have seen. It's size dependent, so we either divide the calls into smaller workloads or we use our own. For your purposes, you can try disabling the Windows watchdog timer.

What about your own? Can you specify it? Much obliged!

It's algorithm dependent I'm afraid.

Thanks for the info... I was having the same issue, and I broke the calls into smaller workloads, and it worked out perfectly. Thanks :)

I was also wondering why the watch dog timer with cula is working where I am not able to execute the same using the cublas. So it is the algorithm you guys use to handle the application works effectively to fix the issues. Thanks for the info.
