Graph algorithms are fundamental to many disciplines and application areas. Large graphs involving millions of vertices are common in scientific and engineering applications. Practical-time implementations using high-end computing resources have been reported but are accessible only to a few. Graphics Processing Units (GPUs) are fast emerging as inexpensive(More)
Graphics Processor Units are used for many general purpose processing due to high compute power available on them. Regular, data-parallel algorithms map well to the SIMD architecture of current GPU. Irregular algorithms on discrete structures like graphs are harder to map to them. Efficient data-mapping primitives can play crucial role in mapping such(More)
Cluster-based tiled display walls can provide cost-effective and scalable displays with high resolution and a large display area. The software to drive them needs to scale too if arbitrarily large displays are to be built. Chromium is a popular software API used to construct such displays. Chromium transparently renders any OpenGL application to a tiled(More)
In this article, we present a parallel prioritized Jacobian-based inverse kinematics algorithm for multithreaded architectures. We solve damped least squares inverse kinematics using a parallel line search by identifying and sampling critical input parameters. Parallel competing execution paths are spawned for each parameter in order to select the optimum(More)
Displays remain flat and passive amidst the many changes in their fundamental technologies. One natural step ahead is to create displays that merge seamlessly in shape and appearance with one’s natural surroundings. In this paper, we present a system to design, render to, and build view-dependent multiplanar displays of arbitrary piecewise-planar shapes,(More)
Displays have seen much improvements over the years, with enhancements in spatial resolution and vertical refresh, etc., to provide better and smoother visual experiences. Color intensity resolution, however, has not changed much over the past few decades. Most displays are still limited to 8-bits per channel. Simultaneously, much work has gone into(More)
