Frees unused memory allocated by the
Intel® MKL
Memory Allocator in the current thread.

  • Module (source):
To improve performance of
Intel® MKL
, the Memory Allocator uses per-thread memory pools where buffers may be collected for fast reuse. The
function frees unused memory allocated by the Memory Allocator in the current thread only.
You should call
after the last call to
Intel® MKL
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® MKL

Product and Performance Information


Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
