3 About the Presenters Arnon Peleg Intel SDK for OpenCL* Applications Product Marketing Manager, Intel Corporation Evgeny Drapkin Principal Engineer, CT Engineering, GE Healthcare 3

4 Contents Introduction to Intel SDK for OpenCL* Applications Benefits of OpenCL Evgeny Drapkin, Principal Engineer, CT Engineering, GE Healthcare Getting Started with: Interoperability with Graphics and Media APIs Debugging and Optimization tools What s Next? 4

5 The Question is. How to get the maximum processing power out of the platform? Compute tasks like task parallelism are best suited to an Intel CPU Other tasks, like image filter workloads, may be best suited to Intel HD Graphics New with 3rd Generation Intel Core Processors with Intel HD Graphics For the first time, developers using Intel architecture have the ability to utilize the compute resources of both the CPU and Intel HD Graphics in an application 5

6 Intel and OpenCL * Standards Intel is a leading participant in OpenCL* standard efforts Intel is a founding member of the OpenCL working group Intel has been an active participant in influencing the OpenCL feature sets 3rd Generation Intel Core Processor supports OpenCL on both CPU and Intel HD Graphics Intel s commitment enables OpenCL applications to scale to future Intel processors 6

7 The BIG idea behind OpenCL* Define a problem domain (Can be 1D/2D/3D space) Replace loops with functions (a kernel) E.g., process a 1024 x 1024 image with one kernel invocation per pixel or 1024 x 1024 = 1,048,576 kernel executions aka work item void scalar_mul(int n, const float *a, const float *b, float *c) { int i; for (i=0; i<n; i++) c[i] = a[i] * b[i]; } Traditional loops Data Parallel OpenCL* kernel void dp_mul(global const float *a, global const float *b, global float *c) { size_t id = get_global_id(0); c[id] = a[id] * b[id]; } // execute over n work-items

8 OpenCL* on 3rd Generation Intel Core Processors System (PC, Server, etc.) OpenCL Platform Layer Provided by hardware vendor (i.e Intel, AMD*, Nvidia*, etc ) Device1 Processor Device2 Graphics Device Intel HD Graphics Compute Unit (1 N) Compute Element Local Memory Device 2 Intel HD Graphics Device 1 Intel Processor (CPU) Intel provides a single platform on 3 rd Generation Intel Core Processors with Intel HD Graphics 4000/2500 8
