The Intel® 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
   }
