Understanding throughput-oriented architectures

November 24th, 2010


For workloads with abundant parallelism, GPUs deliver higher peak computational throughput than latency-oriented CPUs. Key insights of this article: Throughput-oriented processors tackle problems where parallelism is abundant, yielding design decisions different from more traditional latency oriented processors. Due to their design, programming throughput-oriented processors requires much more emphasis on parallelism and scalability than programming sequential processors. GPUs are the leading exemplars of modern throughput-oriented architecture, providing a ubiquitous commodity platform for exploring throughput-oriented programming.

CfP: High Performance Graphics 2011

November 21st, 2010


We are pleased to announce High-Performance Graphics 2011. High Performance Graphics is the leading international forum for performance-oriented graphics systems research including innovative algorithms, efficient implementations, and hardware architecture. The conference brings together researchers, engineers, and architects to discuss the complex interactions of massively parallel hardware, novel programming models, efficient graphics algorithms, and innovative applications. High Performance Graphics was founded in 2009 to synthesize and expand on two important and well-respected conferences in computer graphics:

  • Graphics Hardware: an annual conference focusing on graphics hardware, architecture, and systems since 1986; and
  • Interactive Ray Tracing: an innovative symposium begun in 2006 focusing on the emerging field of interactive ray tracing and global illumination techniques.

By combining and expanding these two communities, we bring to authors and attendees the best of both fields and a conference covering a broad range of interactive 3D graphics systems and algorithm research.

A Highly Efficient GPU Implementation for Variational Optic Flow Based on the Euler-Lagrange Framework

November 21st, 2010


The Euler-Lagrange (EL) framework is the most widely-used strategy for solving variational optic flow methods. We present the first approach that solves the EL equations of state-of-the-art methods on sequences with 640×480 pixels in near-realtime on GPUs. This performance is achieved by combining two ideas: (i) We extend the recently proposed Fast Explicit Diffusion (FED) scheme to optic flow, and additionally embed it into a coarse-to-fine strategy. (ii) We parallelise our complete algorithm on a GPU, where a careful optimisation of global memory operations and an efficient use of on-chip memory guarantee a good performance. Applying our approach to the variational ‘Complementary Optic Flow’ method (Zimmer et al. (2009)), we obtain highly accurate flow fields in less than a second. This currently constitutes the fastest method in the top 10 of the widely used Middlebury benchmark.
