Efficient GPGPU programming with OpenCL

Efficient GPGPU programming with OpenCL

What makes GPGPU computing so enticing is the availability of extreme floating point performance in cost effective GPUs. AMD's top of the line GPU in the AMD Radeon™ HD 6970 desktop graphics card delivers 2.7 single precision TFLOPs (theoretical peak) at a retail cost of about $369. By leveraging economies of scale in the PC industry, GPUs continue to drive higher performance per watt and dollar every year. To benefit from these performance gains, embedded systems need to meet three more challenges: lower power consumption, open standards, and parallel algorithms. Low energy consumption In addition to excellent GFLOPs per dollar, GPGPU computing also delivers high performance per watt. Although the AMD Radeon HD 6970 card has a thermal design power (TDP) of 250W, many server based applications can handle that power to achieve more than 10GFLOPs/W. On the other hand, embedd...
