We present an ultrafast opacity calculator for application to exoplanetary atmospheres, which we name HELIOS-K. It takes a line list as an input, computes the shape of each spectral line (e.g., a Voigt profile) and provides an option for grouping an enormous number of lines into a manageable number of bins. We implement a combination […]

A way to accelerate DEM calculations on the GPUs is developed. We examined how warp divergences take place in the contact detection and the force calculations taking account of the GPU architecture. Then we showed a strategy to reduce the impact of the warp divergences on the runtime of the DEM force calculations.

Graphics Processing Units (GPUs) have numerous configuration and design options, including core frequency, number of parallel compute units (CUs), and available memory bandwidth. At many stages of the design process, it is important to estimate how application performance and power are impacted by these options. This paper describes a GPU performance and power estimation model […]

This paper investigates traffic sign classification, which is an important problem to solve for autonomous driving. Linear discriminant analysis and convolutional neural networks achieved an accuracy of 98.25% and 98.75% respectively when classifying eight different types of traffic signs. The CNN was implemented on a GPU for real-time traffic sign classification: testing time for the […]

Both size and computational activities of Vehicular Area Network (VANET) are growing. Simulation of VANETs not only requires the simulation of network standards, but also the mobility of nodes. Such dynamic system involves computation of node distance, routing protocols, application layer, data send, data receive, etc. The simulation model of VANET requires both hardware and […]

In this paper, we propose RadixBoost, a hardware acceleration structure for scalable 32-bit integer radix sort on GPU. The whole structure is integrated into a GPU microarchitecture as a special functional unit and can be started by new instructions. Our design enables a significantly faster sorting procedure for general purpose GPU computing. The RadixBoost architecture […]

The ray tracing algorithm is well-known for its ability to generate photo-realistic rendering effects. Recent years have witnessed a renewed momentum in pushing it to real-time for better user experience. Today the construction of acceleration structures, e.g., kd-tree, has become the bottleneck of ray tracing. A dedicated hardware architecture, FastTree, was proposed for kd-tree construction […]

We address the increasingly varied capabilities of specialized computing platforms by introducing a growing family of functionally-limited mini-languages, implemented as embedded domain specific languages (EDSLs) in Haskell, that may be composed to harness the computational features offered by a variety of hardware platforms. This development is based on a novel modular representation of the EDSL […]

High-level domain-specific languages for array processing on the GPU are increasingly common, but they typically only run on a single GPU. As computational power is distributed across more devices, languages must target multiple devices simultaneously. To this end, we present a compositional translation that fissions data-parallel programs in the Accelerate language, allowing subsequent compiler and […]
