HUCAA2015 CFP: Workshop on Heterogeneous and Unconventional Cluster Architectures and Applications

April 13th, 2015

4th International Workshop on Heterogeneous and Unconventional Cluster Architectures and Applications (HUCAA 2015)

http://www.hucaa-workshop.org/hucaa2015
Sept. 8-11, 2015 – Chicago, IL, US
In conjunction with IEEE CLUSTER 2015
IEEE International Conference on Cluster Computing

ABOUT THE WORKSHOP

The workshop on Heterogeneous and Unconventional Cluster Architectures
and Applications gears to gather recent work on heterogeneous and
unconventional cluster architectures and applications, which might
have an impact on future mainstream cluster architectures. This
includes any cluster architecture that is not based on the usual
commodity components and therefore makes use of some special hard- or
software elements, or that is used for special and unconventional
applications. Read the rest of this entry »

Graphic-Card Cluster for Astrophysics (GraCCA) — Performance Tests

July 27th, 2007

Abstract: “In this paper, we describe the architecture and performance of the GraCCA system, a Graphic-Card Cluster for Astrophysics simulations. It consists of 16 nodes, with each node equipped with 2 modern graphic cards, the NVIDIA GeForce 8800 GTX. This computing cluster provides a theoretical performance of 16.2 TFLOPS. To demonstrate its performance in astrophysics computation, we have implemented a parallel direct N-body simulation program with shared time-step algorithm in this system. Our system achieves a measured performance of 7.1 TFLOPS and a parallel efficiency of 90% for simulating a globular cluster of 1024K particles. In comparing with the GRAPE-6A cluster at RIT (Rochester Institute of Technology), the GraCCA system achieves a more than twice higher measured speed and an even higher performance-per-dollar ratio. Moreover, our system can handle up to 320M particles and can serve as a general-purpose computing cluster for a wide range of astrophysics problems.
