General Matrix Multiply (GEMM) sample demonstrates how to efficiently utilize an OpenCL™ device to perform general matrix multiply operation on two dense square matrices. The primary target devices that are suitable for this sample are the devices with cache memory: Intel® Xeon Phi™ and Intel® Architecture CPU devices.
This sample illustrates the basic principles of how to work simultaneously with OpenCL™ devices on both CPU and Intel® Processor Graphics.
The sample demonstrates how to implement efficient median filter with OpenCL™ standard. This implementation relies on auto-vectorization performed by Intel® SDK for OpenCL Applications compiler.
The Intel® Media SDK Interoperability sample demonstrates how to use Intel® Media SDK and OpenCL™ technology together for efficient video decoding and fast post-processing.
This sample demonstrates a CPU-optimized implementation of the God Rays effect, showing how to: Implement calculation kernels using the OpenCL™ technology C99 Parallelize the kernels by running several work-groups in parallel Organize data exchange between the host and the OpenCL device
The Tone Mapping sample demonstrates how to use high dynamic range (HDR) rendering with tone mapping effect with OpenCL™ technology.
Demonstrates how to implement an efficient sorting routine with the OpenCL™ technology that operates on arbitrary input array of integer values. The sample uses properties of bitonic sequence and principles of sorting networks and enables efficient SIMD-style parallelism through OpenCL vector data types. The code is designed to work well on modern CPUs.
Simple Optimizations sample demonstrates simple ways of measuring the performance of OpenCL™ kernels in an application. It describes basics of profiling and important caveats like having dedicated “warming” run. It also demonstrates several simple optimizations, some of optimizations are rather CPU-specific (like mapping buffers), while others are more general (like using relaxed-math). The...
HDR Tone Mapping for Post Processing sample features multi-device support, specifically the simultaneous use of CPU and Intel® Processor Graphics OpenCL™ devices.
