Intel® oneAPI Math Kernel Library Developer Reference - C
Frees unused memory allocated by the Intel® oneAPI Math Kernel Library Memory Allocator in the current thread.
void mkl_thread_free_buffers (void);
To improve performance of Intel® oneAPI Math Kernel Library, the Memory Allocator uses per-thread memory pools where buffers may be collected for fast reuse. Themkl_thread_free_buffers function frees unused memory allocated by the Memory Allocator in the current thread only.
You should call mkl_thread_free_buffersafter the last call to Intel® oneAPI Math Kernel Library functions in the current thread. In large applications, if you suspect that the memory may get insufficient, you may call this function earlier, but anticipate a drop in performance that may occur due to reallocation of buffers for subsequent calls to Intel® oneAPI Math Kernel Library functions.
