Silence the struggle around cluster software stack configuration. Caos NSA is a distribution that focuses on making things simple, easy to install and upgrade, and easy to manage.
New tool for taking the output from strace_analyzer and creating a simulation of the I/O pattern of your code on different storage hardware and file systems.
Learn how to obtain, build, and use an MPI stack for Linux machines. This tutorial will take you from "hello world" to parallel matrix multiplication in a matter of minutes.
In case you haven’t noticed, the high-performance computing (HPC) market is now ruled by the Linux cluster. And while Linux clusters have made serious number crunching affordable, this disruptive change still has perils. Unlike more traditional HPC methods, a cluster presents a myriad of variables and trade-offs to the cluster designer and end-user. However, whenever there are choices that aren’t completely right or wrong, there is an opportunity for the artist and engineer to shine in all of us.
A new, federally-funded prograim called the High Productivity Computing Systems Initiative aims to to make high-performance computing more afforadable and more accessible to more scientists. Here’s a look at the goals of the project, including an example of a better way to program in parallel today.
Supercomputing extremists converged on Seattle, Washington, last fall to share their experiences, exhibit their research, flaunt their wares, and award their pioneers.
Those who say that the “Top 500” (http://www.top500.org/) is nothing more than “a high-tech pissing contest” are wrong. As the history of the Top 500 has shown, “The List” has an unfailing ability to predict the future of and inexorably impact plebeian, everyday computing.
Two months ago, the Kronos “value cluster” set a new record for price-to-performance, yielding 14.53 gigaflops at the cost of $171 per gigaflop. But is that the best Kronos can do? Or can some additional investment of time and effort push the extremes a little further? Discover if Kronos hits the proverbial wall, learning more cluster optimization techniques along the way.
LOVELAND, Colorado - 30 November 2005 - Terra Soft Solutions, the leading developer of integrated Power Architecture Linux solutions is pleased to announce its role in COLSA Corporation's success with MACH5, the world’s largest Apple Xserve-based cluster.
If you need to monitor and manage such a configuration, try syslog-ng (syslog, next generation), a drop-in replacement for syslogd. syslog-ng provides more sophisticated log management capabilities and enables log transfers over the Internet.
To date, the Message Passing Interface has been instrumental in simplifying application development for clusters. But as clusters change to embrace multiple cores, multiple platforms, and multiple advanced interconnects, MPI is no longer adequate. What can replace it? Donald Becker asks, “How about Unix? ”
Getting the most out of your cluster is always important. But how exactly is that done? Do you really need to dissect your code and analyze every instruction to get optimal performance? Do you need to build custom kernels? Not necessarily. By testing some basic assumptions, you may be able to eke ten-node performance out of an eight-node cluster. Here’s how.
