Reconfigurable computing (RC) systems based on FPGAs are becoming an increasingly attractive solution to building parallel systems of the future. Applications targeting such systems have demonstrated superior performance and reduced energy consumption versus their traditional counterparts based on microprocessors. However, most of such work has been limited to small system sizes. Unlike traditional HPC systems, […]

Stereo matching based on the Markov random field model has a global optimization problem. Solutions of the problem can be inferred by the belief propagation (BP) algorithm. The BP algorithm effectively estimates global solutions, but it takes a very long time to calculate messages. In this paper, we implement the hierarchical BP algorithm on a […]

To increase the efficiency of the plasma assisted material processing with help of the capacitively coupled plasma discharge frequency of the driven field and spatial size of the modern devices tend to higher values. This can lead to a stronger influence of the electromagnetic effects, which in turn can affect the plasma uniformity, one of […]

We present a visualization technique for simulated fluid dynamics data that visualizes the gradient of the velocity field in an intuitive way. Our work is inspired by rheoscopic particles, which are small, flat particles that, when suspended in fluid, align themselves with the shear of the flow. We adopt the physical principles of real rheoscopic […]

The future of computing is something that is very much on the mind of nVidia CEO Jen-Hsun Huang, not least because he thinks his company is going to have a hand in it. As a maker of graphics processing units (GPUs), nVidia has had more of a walk-on role in the PC. If you want […]

We investigate how to efficiently build bounding volume hierarchies (BVHs) with surface area heuristic (SAH) on the Intel Many Integrated Core (MIC) Architecture. To achieve maximum performance, we use four key concepts: progressive 10-bit quantization to reduce cache footprint with negligible loss in BVH quality; an AoSoA data layout that allows efficient streaming and SIMD […]

Recent developments in Graphics Processing Units (GPUs) have enabled inexpensive high performance computing for general-purpose applications. Due to GPU’s tremendous computing capability, it has emerged as the co-processor of the CPU to achieve a high overall throughput. CUDA programming model provides the programmers adequate C language like APIs to better exploit the parallel power of […]

High dynamic range rendering attempts to take an HDR image and produce a more realistic representation on a limited range computer monitor. Although several tone mapping operators have been proposed in recent years, no evaluation has yet been undertaken to explore which operator is more suitable for hardware implementation. In this paper, we begin with […]

In this paper we present a compression scheme for large point scans including per-point normals. For the encoding of such scans we introduce a particular type of closest sphere packing grids, the hexagonal close packing (HCP). HCP grids provide a structure for an optimal packing of 3D space, and for a given sampling error they […]

In this paper, we explore the implementation of fault table generation on a Graphics Processing Unit (GPU). A fault table is essential for fault diagnosis and fault detection in VLSI testing and debug. Generating a fault table requires extensive fault simulation, with no fault dropping, and is extremely expensive from a computational standpoint. Fault simulation […]

Large-scale scenarios of vehicular traffic simulation problems are characterized by complex queuing effects, control mechanisms and other interactions of the traffic on the control and vice versa. While small-sized scenarios are relatively easy to explore and analyze, larger scenarios need specialized treatment for efficient execution. The simulation challenges of speed and scale become pronounced when […]

This paper proposes a novel six-face spherical map, isocube, that fully utilizes the cubemap hardware built in most GPUs. Unlike the cubemap, the proposed isocube uniformly samples the unit sphere (uniformly distributed), and all samples span the same solid angle (equally important). Its mapping computation contains only a small overhead. By feeding the cubemap hardware […]
