Big Data applications are trivially parallelizable because they typically consist of simple and straightforward operations performed on a large number of independent input records. GPUs appear to be particularly well suited for this class of applications given their high degree of parallelism and high memory bandwidth. However, a number of issues severely complicate matters when […]

Manycores are consolidating in HPC community as a way of improving performance while keeping power efficiency. Knights Landing is the recently released second generation of Intel Xeon Phi architecture. While optimizing applications on CPUs, GPUs and first Xeon Phi’s has been largely studied in the last years, the new features in Knights Landing processors require […]

In this paper we present STAR-RT – the first working prototype of Selective Tuning Attention Reference (STAR) model and Cognitive Programs (CPs). The Selective Tuning (ST) model received substantial support through psychological and neurophysiological experiments. The STAR framework expands ST and applies it to practical visual tasks. In order to do so, similarly to many […]

This document intends to provide a detailed guidance on how to optimize OpenCL programs with Adreno GPUs. A good amount of information has been provided to help developers understand the OpenCL fundamentals and Adreno architectures, and most importantly, master OpenCL optimization techniques. OpenCL optimization is often challenging and requires a lot of trial and error. […]

OpenMP is a shared memory programming model which supports the offloading of target regions to accelerators such as NVIDIA GPUs. The implementation in Clang/LLVM aims to deliver a generic GPU compilation toolchain that supports both the native CUDA C/C++ and the OpenMP device offloading models. There are situations where the semantics of OpenMP and those […]

Image convolution is widely used for sharpening, blurring and edge detection. In this paper, we review two common algorithms for convolving a 2D image by a separable kernel (filter). After optimising the naive codes using loop unrolling and SIMD vectorisation, we choose the algorithm with better performance as the baseline for parallelisation. We then compare […]

In recent years, Convolutional Neural Networks (ConvNets) have become an enabling technology for a wide range of novel embedded Artificial Intelligence systems. Across the range of applications, the performance needs vary significantly, from high-throughput video surveillance to the very low-latency requirements of autonomous cars. In this context, FPGAs can provide a potential platform that can […]

The Intel FPGA SDK for OpenCL Programming Guide provides descriptions, recommendations and usage information on the Intel Software Development Kit (SDK) for OpenCL compiler and tools. The Intel FPGA SDK for OpenCL is an OpenCL-based heterogeneous parallel programming environment for Intel FPGA products.
