Porting Guide (benchmark)
Introduction
To permit benchmark to work on a range of platforms a porting abstraction layer has been written. Porting simply involves implementing the porting abstraction layer; the library will then compile and work. Implementation involves providing values to a small set defines, macros and typedefs and implementing one or two functions.
The Porting Abstraction Layer
The porting abstraction layer consists of two C and one header files, thus;
└───test_and_benchmark
└───benchmark
└───src
├───porting_abstraction_layer_numa_free.c
├───porting_abstraction_layer_numa_malloc.c
└───porting_abstraction_layer_operating_system.h
Accordingly, to add a new platform, introduce a new #ifdef, which matches the appropriate compiler defined macros for your platform.
The NUMA free/malloc functions only need to be implemented on NUMA systems. On SMP systems, a hosted implementation is assumed, and malloc is used.
porting_abstraction_layer_numa_free.c
void benchmark_pal_numa_free( void *memory, lfds710_pal_uint_t size_in_bytes );
porting_abstraction_layer_numa_malloc.c
void benchmark_pal_numa_malloc( lfds710_pal_uint_t numa_node_id, lfds710_pal_uint_t size_in_bytes );
