Testing Your Linux Cluster
The first program we will run is cpilog. From within the mpich-.2.2.3/examples/basic directory, copy the cpilog exec file (if this file isn’t present, use make command again) to your top-level directory. On our cluster, this is either /root (if we are logged in as root) or /home/DevArticle, if we are logged in as DevArticle (we have installed MPICH both places).
Next, from your top directory, rcp the cpilog file to each node in your cluster, placing the file in the corresponding directory on each node. For example, if I am logged in as DevArticle on the master node, I’ll issue rcp cpilog Slave:/home/ DevArticle to copy cpilog to the DevArticle directory on Slave. I’ll do the same for each node (if there are more than two nodes). If I want to run a program as root, then I’ll copy the cpilog file to the root directories of all nodes on the cluster.
Building a Linux Cluster
Linux clusters are generally more common, robust, efficient and cost effective than Windows clusters. We will now look at the steps involved in building up a Linux cluster. For more information go here .
Building a super computer – Introduction
Why pay $10 million for a supercomputer when this article can show you how to build your own supercomputer cluster with just a handful of Windows/Linux PC’s…
James Cameron’s Titanic (the movie) special effects crew couldn’t afford a supercomputer to do the critical rendering, and anything less would take far too long.
