Intel's Memory Allocator Library
Intel's
libqkmalloc
library for fast memory allocation provides a C-level interface for memory allocation that is optimized for performance.
You can link the
libqkmalloc
library as a shared library only on Linux platforms for Intel® 64 architecture. This library provides optimized implementation of standard allocation routines
malloc
,
calloc
,
realloc
, and
free
, and is C99 standard compliant.
This library is limited to work only on Intel® processors and will redirect to standard C routines at runtime if used on non-Intel® processors.
Use Intel's Custom Memory Allocator Library
You can use the
libqkmalloc
library by linking directly to it or by using the
LD_PRELOAD
environment variable.
To ensure that the application overrides the standard library allocation routines with
libqkmalloc
, set the environment variable
LD_PRELOAD
in the command line before the application execution. This environment variable allows you to set a library path that loads before any other library (including the C runtime library). The application uses symbols from the specified library instead of symbols from the standard library.
Restrictions
This library does not support threaded code
such as OpenMP*
and is not thread-safe. It should not be used simultaneously from multiple threads. For the best results, this library should be used with large throughput workloads.
