CUDA 6.5: Something for Nothing

By Ian Lumb | September 17, 2014

Who says you can’t get something for nothing? With CUDA 6.5, you can! The something is improved performance. The nothing is no code change required.

NVIDIA made improved performance a focal point of the recent CUDA 6.5 release. For example, if you make use of CUDA-enabled FFTs and/or sparse-matrix routines, all you’ll need to do is recompile your application with this latest release of the toolkit. You’ll see performance improvements without having to change a single character in your source code. Even the size of object files can be optimized through use of the nvprune utility.

HPC Cluster Helps Advance the Wave Energy Industry

By Bright Staff | September 09, 2014

HPC Wire recently reported that the advances taking place in the wave energy industry by Pelamis Wave Power are due in part to an HPC cluster called INDY that provides highly detailed numerical simulations to analyze the performance of the machines that convert wave energy into electricity.

Wave farms are offshore or near shore locations in which these machines are placed, the article stated. The electricity they create is transmitted to shore by subsea cables and other equipment. The machines that Pelamis developed were initially designed using a small-scale cluster computing platform. However, with a 3MW operation being planned for Scotland, the company has now begun using the HPC resources of Edinburgh Parallel Computing Centre.

So Much To See At ISC

By Lionel Gibbons | June 18, 2014

Well, it's that time of year again. Time for the International Supercomputing Conference (ISC), Europe's premiere event for people interested in just about anything related to high performance computing.

We're proud to be back again this year, sponsoring the 2014 event in Leipzig, Germany where we'll be showcasing some of the new capabilities in Bright Cluster Manager 7. Our CTO, Martijn de Vries will be giving a presentation in the Exhibitor Forum, and we'll be running live demos in our booth (#740).

We have so much to talk about this year. First up are the new HPC cluster management features available in version 7. But that's not all. We will also be demonstrating Bright Cluster Manager's new ability to manage Hadoop clusters and OpenStack clouds right alongside HPC clusters. Members of our develoment team will be on hand to show you how it works, and answer any questions you have.

So if your day job involves managing clusters of any kind, stop by and see us at ISC14. We'll show you how an enterprise-grade cluster manager can make your life so much easier.

Managing the Impact of Interactive Use, Part 2: Interactive Workloads via Bright

By Ian Lumb | October 16, 2013

Because the impact of unmanaged interactive sessions can be significant,[1] the concept of login nodes in Bright Cluster Manager was introduced in Part 1 of this series.[2] Although login nodes address many considerations relating to interactive use, they are designed to do so in a limited way. For example, in Part 1, the following consideration was outlined (emphasis added here):

Managing the Impact of Interactive Use, Part 1: Introducing Login Nodes via Bright

By Ian Lumb | September 25, 2013

Whether it’s force of habit, or from actual need, users of HPC environments crave interactivity. Because the impact of unmanaged interactive sessions can be significant, there exists the potential for concern. Is it possible to meet users’ need for interactivity while managing the potential for impact? In this first part of a two-part series on managing interactive impact, attention focuses on the introduction of login nodes to a cluster managed by Bright Cluster Manager. The second part in this series will focus on use of workload managers as a complementary means for managing the interactive impact on the compute nodes of a cluster.

Executing Custom Shell Commands through Bright Cluster Manager

By Ian Lumb | July 23, 2013

Bright Cluster Manager includes an interactive shell known as CMSH. Owing to personal preference, or the task at hand, Bright admins might choose the Command-Line Interface (CLI) for cluster management rather than the Bright GUI.
