Path to Petascale: Adapting GEO/CHEM/ASTRO Applications for Accelerators and Accelerator Clusters

June 4th, 2009

The goal of this workshop, held at the National Center for Supercomputing Applications, University of Illinois at Urbana-Champaign, was to help computational scientists in the geosciences, computational chemistry, and astronomy and astrophysics communities take full advantage of emerging high-performance computing resources based on computational accelerators, such as clusters with GPUs and Cell processors.

Slides are now available online and cover a wide range of topics including

  • GPU and Cell programming tutorials
  • GPU and Cell technology
  • Accelerator programming, clusters, frameworks and building blocks such as sparse matrix-vector products, tree-based algorithms and in particular accelerator integration into large-scale established code bases
  • Case studies and posters from geosciences, computational chemistry and astronomy/astrophysics such as the simulation of earthquakes, molecular dynamics, solar radiation, tsunamis, weather predictions, climate modeling and n-body systems as well as Monte-Carlo, Euler, Navier-Stokes and Lattice-Boltzmann type of simulations

Workshop on Parallel Satisfiability Solving on New Architectures

May 31st, 2009

During the last decade, the fundamental Satisfiability Problem (SAT) has been extensively studied. The interest of the community significantly grows because of its conceptual simplicity and its ability to describe a wide set of various problems, including hardware verification, planning, automated reasoning, and others. Consequently, there is an increasing demand for high performance SAT-solving algorithms in industry. In spite of the actual trend in processor development, which is moving from single-core to multicore CPU, there exist few parallel solving approaches dedicated to SAT problems using shared memory architectures.

This workshop will focus on SAT and beyond SAT solving techniques exploiting parallelism in emerging massively multithreaded and multicore architectures. Recently, Graphics Processing Units (GPUs) have evolved to address programming of general-purpose computations. The workshop will particularly focus on the use of GPUs and coprocessor computing techniques to overcome traditional barriers to parallelization.

The workshop invites papers in this emerging discipline which includes, but is not limited to, the following areas of interest.

  • Satisfiability Solving Using Shared Memory
  • General-Purpose Computation on GPUs (GPGPU) for SAT
  • Reconfigurable Computing and FPGA for SAT
  • Parallel SAT, MaxSAT, #SAT and QBF pre-processing

University of Melbourne Workshop: High-Performance GPU Computing with NVIDIA CUDA

May 12th, 2009

A half-day workshop and discussion forum will be held from 8:45-13:00, Wednesday May 27, in Lecture theatre 3 of the Alan Gilbert Building at The University of Melbourne, Victoria, Australia. A  light lunch will be supplied afterwards from 13:00-14:00. With speakers from NVIDIA and Xenon Systems, this workshop is hosted by the ARC Centre of Excellence for Mathematics and Statistics of Complex Systems (MASCOS), and the Department of Mathematics and Statistics at the University of Melbourne.

Due to recent advances in GPU hardware and software, so called general-purpose GPU computing (GPGPU) is rapidly expanding from niche applications to the mainstream of high performance computing. For HPC researchers, hardware gains have increased the imperative to learn this new computing paradigm, while high level programming languages (in particular, CUDA) have decreased the barrier to entry to this field, so that it is now possible for new developers to rapidly port suitable applications from C/C++ running on CPUs to CUDA running on GPUs. For appropriate applications, GPUs have significant, even dramatic, advantages compared to CPUs in terms of both Dollars/FLOPS and Watts/FLOPS.
