IntelĀ® MPI Library Reference Manual for Linux* OS
The IntelĀ® MPI Library provides a way to replace the memory management subsystem by a user-defined package. You may optionally set the following function pointers:
i_malloc
i_calloc
i_realloc
i_free
These pointers also affect the C++ new and delete operators.
The respective standard C library functions are used by default.
The following contrived source code snippet illustrates the usage of the unified memory subsystem:
#include <i_malloc.h> #include <my_malloc.h> int main( int argc, int argv ) { // override normal pointers i_malloc = my_malloc; i_calloc = my_calloc; i_realloc = my_realloc; i_free = my_free; #ifdef _WIN32 // also override pointers used by DLLs i_malloc_dll = my_malloc; i_calloc_dll = my_calloc; i_realloc_dll = my_realloc; i_free_dll = my_free; #endif // now start using Intel(R) libraries }
