Building a Linux cluster on a budget

Post date: November 18, 2005, 19:11 Category: Network Views: 3962 Comments
Tutorial quote: So you need a lot of computing power but don't want to spend tens of thousands of dollars on a commercial cluster? Or maybe you just have a lot of machines sitting idle that you would like to put to good use? You can build a powerful and scalable Linux cluster using only free software and off-the-shelf components. Here's how.

Building a Linux Cluster, Part 2

Post date: April 18, 2005, 03:04 Category: Network Views: 2749 Comments
Tutorial quote: In this installment, we consider the what of cluster building: the hardware and software components that make up a Linux cluster, and some ways to think about integrating them into a solution for your environment.

Building a Linux Cluster, Part 3: How To Get Started

Post date: April 25, 2005, 14:04 Category: Network Views: 2597 Comments
Tutorial quote: In the previous two articles in this series, we examined some of the whys and whats of building Linux clusters. This article concludes our series by concentrating on the hows of cluster building. We've seen that a clustered approach to certain computing solutions can save lots of money in hardware and support costs. Now our job is to produce a method of building clusters that's repeatable and predictable—we don't want to give back our hard-won savings in project cost overruns.

Building a Linux virtual server

Post date: June 9, 2005, 14:06 Category: Software Views: 2967 Comments
Tutorial quote: With the explosive growth of the Internet, the workload on servers providing Web, email, and media services has increased greatly. More and more sites are being challenged to keep up with the growing demands and are employing several techniques to avoid overloading their servers. Building a scalable server on a cluster of computers is one of the solutions that is being effectively put to use. With such a cluster, the increasing requests can be easily managed by simply adding one or more new servers to the existing cluster as required. In this article we will look at setting up one such scalable, network load-balancing server cluster using a virtual server via the Linux Virtual Server Project.

Building a Virtual Cluster with Xen

Post date: September 28, 2006, 04:09 Category: Emulation Views: 7472 Comments
Tutorial quote: It is a common practice to have development and test servers for each production server, so that you can experiment with changes without the fear of breaking anything important, but this is usually not feasible with clusters. So how do you try that new version of your favorite program before committing it to the production cluster? A cheap and convenient possibility is to build a virtual cluster.

Thanks to the Xen virtual machine monitor, you can create a number of virtual machines, all running simultaneously in your computer, install different operating systems in them, or just different configurations, and connect them via (virtual) network cards. Xen is a terrific tool for building virtual Beowulf clusters. It can prove useful when learning or teaching about clusters or for testing new features/software without the fear of causing major damage to an existing cluster.

Gnu Queue: Linux Clustering Made Easy

Post date: December 22, 2005, 19:12 Category: System Views: 2937 Comments
Tutorial quote: GNU Queue makes it easy to cluster Linux workstations. If you already know how to control jobs running on your local machine, you already know how to control remote jobs using GNU Queue. You don't even need special privileges to install and run GNU Queue on your cluster--anyone can do it. Once you've discovered how incredibly easy it is to cluster Linux environments with GNU Queue, you'll wonder why organizations continue to spend so much money on comparatively hard-to-cluster Windows NT environments.

Building A Linux Router

Post date: February 26, 2007, 07:02 Category: Miscellaneous Views: 8058 Comments
Tutorial quote: Building a reliable, full-featured broadband router can be very easy and cost-efficient. This article is about building one for routing a LAN to the Internet with NAT (Network Address Translation -- Linux users also call it as IP Masquerading) using an old computer and a Linux micro-distribution designed to have very low hardware requirements. We'll end up having a very simple and stable system, yet featuring e.g. iptables based stateful firewalling and remote administration.

How To Set Up A Load-Balanced MySQL Cluster With MySQL 5.1

Post date: June 17, 2008, 09:06 Category: Installing Views: 3340 Comments
Tutorial quote: This tutorial shows how to configure a MySQL 5.1 cluster with five nodes: 1 x management, 2 x storage nodes and 2 x balancer nodes. This cluster is load-balanced by an Ultra Monkey package which provides heartbeat (for checking if the other node is still alive) and ldirectord (to split up the requests to the nodes of the MySQL cluster).

Xen Virtualization and Linux Clustering, Part 2

Post date: January 21, 2006, 06:01 Category: System Views: 2980 Comments
Tutorial quote: We ended last time after configuring our first unprivileged Xen domain. In this article, we complete our cluster and then test it using an open-source parallel ray tracer. The first thing we need to do is create additional slave nodes to be used with the cluster. So, let's get down to business.

Building a Linux Cluster, Part 1

Post date: April 18, 2005, 03:04 Category: Network Views: 2383 Comments
Tutorial quote: Linux clusters have escaped. As the general popularity of the Linux operating system increases, more complex solutions built with it are becoming increasingly common in the "traditional" (more conservative) IT world. Linux computer clusters, whose provenance was originally universities and research institutions such as the U.S. National Laboratories, are showing up in increasing numbers as high-performance computing solutions within such areas as oil and gas exploration, computer-aided engineering, visualization, and software development. Linux clusters providing highly-available web, mail, and other infrastructure services are also increasingly common. If past computing history is any indicator of future trends, widespread use of Linux clusters in the mainstream IT world cannot be far behind.
