mkl_mem_stat

Reports the status of the
Intel® oneAPI Math Kernel Library
 Memory Allocator.

AllocatedBuffers
);

Output Parameters
Name
Type
Description
AllocatedBuffers
int
The number of buffers allocated by
Intel® oneAPI Math Kernel Library
.
Description
The function returns the number of buffers allocated by
Intel® oneAPI Math Kernel Library
 and the amount of memory in these buffers.
Intel® oneAPI Math Kernel Library
 can allocate the memory buffers internally or in a call tomkl_malloc/mkl_calloc. If no buffers are allocated at the moment, the
mkl_mem_stat
 function returns 0. Call
mkl_mem_stat
to check the
Intel® oneAPI Math Kernel Library
 memory status.
If you free all the memory allocated in calls to
mkl_malloc
 or
mkl_calloc
 and then call
mkl_free_buffers
, a subsequent call to
mkl_mem_stat
 normally returns 0.
Return Values
Name
Type
Description
AllocatedBytes
MKL_INT64
The amount of allocated memory (in bytes).

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.
