Managing Memory

To improve performance of your application that calls
Intel DAAL
, align your arrays on 64-byte boundaries and ensure that the leading dimensions of the arrays are divisible by 64. For that purpose
Intel DAAL
functions to allocate and deallocate memory.
To allocate memory, call
with the specified size of the buffer to be allocated and the alignment of the buffer, which must be a power of 2. If the specified alignment is not a power of 2, the library uses the 32-byte alignment.
To deallocate memory allocated earlier by the
function, call the
function and set a pointer to the buffer to be freed.

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.
