DKMalloc

Memory pool allocator. C / C++.
Optimized for quick alloc, realloc, free.
The allocated memory is always 16 bytes aligned.

You can use DKMalloc for your project.
Build DKMalloc as a shared library / DLL for C projects that can not use C++.
(essential functions are defined as C-linkage)

This is simplified ‘Memory Allocator’ part of DKGL.

Performance Test

1. Choose which allocator to test.

   • To test system default malloc with DKMalloc
     1. Set 1 to TEST_SYSTEM_DEFAULT_MALLOC at main.cpp line 14

         #define TEST_SYSTEM_DEFAULT_MALLOC 1

   • To test Intel TBB* with DKMalloc
     1. You have to install Intel TBB and set up header path
     2. Set 1 to TEST_TBB_SCALABLE_ALLOCATOR at main.cpp line 15

         #define TEST_TBB_SCALABLE_ALLOCATOR 1

2. Decide testing for small blocks or large blocks at main.cpp line 17

    #define TEST_LARGE_BLOCKS 0     // set 1 to test large-blocks

   • Set 0 to test small blocks (default)
   • Set 1 to test large blocks

3. Adjust allocation unit count at main.cpp line 19 or 20

   • for testing small blocks (line 19)

       #define NUM_ALLOCATIONS_SMALL_BLOCKS 20000000    // num allocs for small blocks

   • for testing large blocks (line 20)

       #define NUM_ALLOCATIONS_LARGE_BLOCKS 1000000    // num allocs for large blocks

4. Build and Run with X64 RELEASE MODE
