When running, Intel® oneAPI Math Kernel Library (oneMKL) may allocate and deallocate internal buffers to facilitate better performance. Memory leaks can occur if the Intel® oneAPI Math Kernel Library is unloaded before freeing the internal buffers.

You can free the internal buffers by calling the

mkl_free_buffers()

function or, for more granular control, the

mkl_thread_free_buffers()

function.

Alternatively, setting the

MKL_DISABLE_FAST_MM

environment variable to

1

or calling the

mkl_disable_fast_mm()

function disables the internal memory manager. Be aware that this change may negatively impact the performance of some oneMKL functions, especially for small problem sizes.
