Fifteen years ago I wrote a short article entitled "How Will You Program 1000 Processors?" Back then it was a good question that had no easy answer. Today, it is still a good question that still has no easy answer. Except now it seems a bit more urgent as we step into the "mulit-core" era. Today, 1000 processors are a reality for many practitioners of Linux HPC.

Don't have cluster hardware, not to worry. Using Xen and some basic PC hardware, you can build a virtual cluster to test ideas, software, and learn about clusters. The article provides step by step directions on how to configure a cluster with five virtual nodes on a single system.

In the article Robert Brown looks at choosing Linux cluster hardware. He is not going to tell you what kind of hardware to buy, but more importantly, how to navigate the ever changing and complex hardware landscape. Cost and benefit are going to be two key words in this article. If you are interested in real cluster HPC, this article is a great place to begin.

Linux cluster optimization is often considered an art form. In some cases it is less art and more like flipping a coin. Just how much performance can you get out of a commodity cluster? Or simply put when do you hit the cluster wall. In this article, no stone is left unturned in an effort to maximize cluster performance.

The software world is becoming more distributed every day. The rise of multi-core processors, clusters, and grids means thinking about parallel program execution. Before you plan world domination though parallel computing, you may want to learn some of the basics rules of the game.

Getting the most out of your cluster is always important. But how does one do this? Do you really need to dissect your code and analyze every instruction to get optimal performance?

In this extensive review, Cluster Monkey Jeff Layton, provides an overview of the available Linux cluster interconnect technologies. This article is the first ever attempt to provide a comprehensive look at cluster interconnects. It concludes with two tables summarizing key features and pricing for various size clusters.

Getting started with what appears to be a very powerful, very complex idea (in computing, at least) is often a daunting proposition, and Linux cluster computing is no exception. There is so much to learn! So many things can go wrong! It might require new, specialized, expensive hardware and software! But wait!

From an industrial perspective, Linux HPC seems to be a "look, but don't touch" technology. While there is an acknowledged need for HPC by many industrial sectors, the HPC market has traditionally focused on the grand challenge or the "heroic" computing needs of the National Labs and Computing centers.

Build a Linux cluster for under $2500. That is crazy -- or maybe not. Join Doug and Jeff as they undertake this outrageous project.
