MKL PARDISO pivot function fault

YC_H_ — Fri, 19 Dec 2014 01:00:58 GMT

HI all,

I tried to implement mkl_pardiso_pivot() in my program.

Sometime, it will cause a segmentation fault in a function in mkl_intel_thread.so.

Does anyone experience the same situation?

This is an unknown problem for the current ( 11.2.1 ) version of MKL. What version are you using? Can you give the example?

Hi,

I encountered this problem since 11.2.0.

Sometime it works fine.

I used debugger to trace down this problem and found that It crashed in opm_xxx functions in mkl_intel_thread.so.

At first, I thought it's my problem to misuse the threading but I didn't do anything about it.

Hope that there is an explanation and resolution about it.

Thanks!
