Usage of mkl_free_buffers

[erling_andersen]

Suppose I have an application that links MKL static and nonthreaded. Also assume I call MKL functions from several threads.

That should be fine. However, now I speculate how

mkl_free_buffers

works in this setting.

Can I call at any time and it will not crash? What if I call the function and buffer is in use?

Should I use another function to free all the buffers.

Hi,

mkl_free_buffers function just releases memory for that buffers which are not in use and marked internally as free.
So, such buffers are conditionally taken to be used fast if such buffer will be required.
