DGMA_P2P

Samples showing FirePro DirectGMA features in OpenGL, DX11 and OpenCL

System Setup

Your system needs 2 AMD GPUs with the DirectGMA feature, and the latest GPU driver. Plug at least 1 monitor on each GPU.

Enable DirectGMA

Before running your DirectGMA samples, you have to make sure that the DirectGMA feature is enabled:

on Windows: AMD Firepro Control Center -> AMD Firepro -> SDI/DirectGMA -> Check the checkbox of the 2 GPU -> Apply -> Restart your computer.

on Linux: in your terminal, enter the commands :

aticonfig --initial=dual-head --adapter=all -f aticonfig --set-pcs-val=MCIL,DMAOGLExtensionApertureMB,96 aticonfig --set-pcs-u32=KERNEL,InitialPhysicalUswcUsageSize,96 and reboot.

Building the source code

For Visual Studio users, each sample has its Visual Studio 2010 solution file, it will also work on more recent version of visual studio:

• GPUtoGPU_OpenCL\GPUtoGPU_OpenCL.sln
• GPUtoGPU_OpenGL\GPUtoGPU_OpenGL.sln
• GPUtoGPU_DX11\GPUtoGPU_DX11.sln

For Linux users, each sample has its Makefile:

• GPUtoGPU_OpenCL\GPUtoGPU_OpenCL\Makefile
• GPUtoGPU_OpenGL\GPUtoGPU_OpenGL\Makefile

Before building the GPUtoGPU_OpenCL project, install the AMD APP SDK, The include and libraries directories point to this SDK using AMDAPPSDKROOT environment variable. This variable will be set when installing the SDK

Before building the GPUtoGPU_DX11, install the Microsoft DirectX SDK (June 2010), and check that your include&lib directories are correct in your Visual Studio solution. The ones used in this SDK are: C:\Program Files (x86)\Microsoft DirectX SDK (June 2010)\Include and C:\Program Files (x86)\Microsoft DirectX SDK (June 2010)\Lib\x86
