Avoiding Memory Leaks in
oneMKL

When running,

Intel® oneAPI Math Kernel Library

allocates and deallocates internal buffers to facilitate better performance. However, in some cases this behavior may result in memory leaks.

To avoid memory leaks, you can do either of the following:

Set the

MKL_DISABLE_FAST_MM

environment variable to 1 or call the

mkl_disable_fast_mm()

function.

Be aware that this change may negatively impact performance of some

Intel® oneAPI Math Kernel Library

functions, especially for small problem sizes.

Call the

mkl_free_buffers()

function or the

mkl_thread_free_buffers()

function in the current thread.

For the descriptions of the memory functions, see the

Intel® oneAPI Math Kernel Library

Developer Reference, available in the Intel Software Documentation Library.
