Minimum Stack Size for MKL fast Memory Management

Jason_Jones1 — Mon, 19 Jul 2010 16:23:19 GMT

I have been getting data corruption and segmentation faults running mkl functions inside separate "pthreads" with mkl fast memory management turned on (I have no problems withmkl fast memoryturned off).

How large does the stack need to be to run mkl functions with mkl fast memory management enabled?

I assume this will be platform dependent - so maybe "how do I determine the minimum stack size needed to call mkl functions?" may be more correct. I knowhow to set it for my pthreads - I just need to know what minimum MKL needs.

Thanks!

Yes, I would be happy to send that to you. It will take some work to extract the relevant portions from the rest of the app. When I get a test example ready how should I send it to you?
