Evaluating and Optimizing OpenCL Kernels for High Performance Computing with FPGAs Abstract: We evaluate the power and performance of the Rodinia benchmark suite using the Altera SDK for OpenCL targeting a Stratix V FPGA against a modern CPU and GPU. Convolutional Neural Networks (CNNs) have been shown to be extremely effective at complex image recognition problems. , The original document contains color images. The latest Tweets from OpenCL on FPGAs (@OpenCLonFPGAs). In this paper, we present a directive-based, high-level optimization framework for high-performance computing with FP-. Channel by @StreamComputing specially for #OpenCL on FPGAs. In the previous section the usage of odeint in combination with Thrust was shown. Most of its key features like multithreading, vector. Efficient compilation of CUDA kernels for high-performance. Learning the basics of the distributed version control system Git. The project contains kernels written in OpenCL and a host code with high resemblance to the original benchmark to measure the global memory bandwidth of an FPGA card. Each compute device contains one or more compute units. Zohouri, N. Optimizing OpenCL Kernels for Iterative Statistical Algorithms on GPUs. In this paper, we present four implementations of K-means data clustering algorithm for different high performance computing platforms. The advantage of OpenCL makes the design to be portable on all the available graphics processing devices and multi core processors. edu Mauricio Breternitz AMD mauricio. When mapping to OpenCL model, each shader core executes one or several work groups. conformant SDK for FPGAs. The first half of the course focuses on the optimization of.
