# 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.
Full version of DKGL: https://github.com/DKGL/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**
```cpp
#define TEST_SYSTEM_DEFAULT_MALLOC 1
```
- To test **Intel TBB*** with DKMalloc
1. You have to install Intel TBB and set up header path
1. Set 1 to TEST_TBB_SCALABLE_ALLOCATOR at **main.cpp** line **15**
```cpp
#define TEST_TBB_SCALABLE_ALLOCATOR 1
```
1. Decide testing for small blocks or large blocks at **main.cpp** line **17**
```cpp
#define TEST_LARGE_BLOCKS 0 // set 1 to test large-blocks
```
- Set 0 to test small blocks (default)
- Set 1 to test large blocks
1. Adjust allocation unit count at **main.cpp** line **19** or **20**
- for testing small blocks (line 19)
```cpp
#define NUM_ALLOCATIONS_SMALL_BLOCKS 20000000 // num allocs for small blocks
```
- for testing large blocks (line 20)
```cpp
#define NUM_ALLOCATIONS_LARGE_BLOCKS 1000000 // num allocs for large blocks
```
1. Build and Run with **X64 RELEASE MODE**
