Webinar: Next Steps for Folding@Home — a Distributed Computing Project for Protein Folding, by Vijay PandeJune 3rd, 2014
Folding@Home is a large-scale volunteer distributed computing project started in 2000 by Vijay Pande, Stanford. For over a decade, Professor Pande’s group has increased the computing power of Folding@Home through the development of new software algorithms and infrastructure, such as the incorporation of new hardware innovations like GPUs. That tremendous computing power has enabled significant advances in the simulation and understanding of diseases like Alzheimer’s Disease, malaria, various cancers, and other diseases at the molecular scale. Professor Pande will give a brief introduction to Folding@Home and the successes in the project so far. He will also discuss plans to greatly enhance Folding@Home capabilities through new initiatives. This webinar is planned for June 3rd, 2014 at 9.00 AM Pacific Time. Register at: http://bit.ly/FolHome
Join the free webinar on May 20th devoted to accelerating orthorectification, atmospheric correction, and transformations for big data with GPUs. Learn how GPU capabilities can improve time for processing large imagery 50-100 times faster. Amanda O’Connor, a Senior Solutions Engineer at Exelis will walk you through implementation of GPU processing for large imagery datasets, operational use of GPU processing for orthorectification and share benchmarks against desktop algorithms.

This webinar covers how Geoweb3d uses the GPU for real-time geospatial 3D visualization, modeling, and analytics. Geoweb3D will demonstrate how native, high resolution datasets including GIS, CAD, 3D Models, LIDAR, and FMV are fused together in real-time with game quality graphics and pixel accurate analysis. The 3D engine uses a GPU resident mesh that adapts to any resolution data on the fly eliminating the need to preprocess any data prior to real-time use. Demonstration will include Geoweb3d Mobile which now uses HTML5 for use on any device in the cloud including phones and tablets.

On March 5 at 11:00am (PST), Acceleware hosts a webinar on accelerating a seismic algorithm on a cluster of AMD GPU compute nodes. The presentation will begin with an outline of the full waveform inversion (FWI) algorithm, followed by an introduction to OpenCL. The OpenCL programming model and memory spaces will be introduced. Strategies for formulating the problem to take advantage of the massively parallel GPU architecture, and key optimizations techniques are discussed including coalescing and an iterative approach to handle the slices. Performance results for the GPU are compared to the CPU run times. Click here to register.
This webinar will demonstrate how real-world computational research in soft matter physics can be accelerated on a GPU-equipped desktop computer with the HOOMD-blue molecular dynamics software. A presentation of how to set up a simulation of a dense polymer liquid, and how to analyze and visualize the results is provided. There will be a demonstration of how self-assembled ordered structures of block copolymers emerge out of an initially disordered configuration. With external potentials, an artificially ordered phase can be produced as well. HOOMD-blue’s easy-to-use scripting interface and plug-ins are used to create a productive work-flow and extend its capabilities. As an advanced topic, there will be a discussion of how the upcoming version of HOOMD-blue can be used on compute clusters running on ten to hundreds of GPUs in parallel, to boost simulations of long polymer chains or large-scale systems.
January 21, 2014, 11:00 a.m. EST, Registration required.
