Hey,
I read this on a site a few minutes ago, and I'm not quite sure what it means:
"In September 2001 Hewlett-Packard clustered 225 PCs running the Open Source Linux operating system. The resulting system (called I-cluster) benchmarked itself right into the global top-500 of supercomputers, using nothing but unmodified, out-of-the-box hardware. (A significant number of entries in that top-500, by the way, runs Linux, and more and more Unix clusters are being used for supercomputing applications.) "
I'm not sure what clustering is. Could anyone give me a simple explanation of what they mean by clusters? I know a good deal about networking (mainly network programming), but I've never learnt about clustering (or scalability for that matter). So could someone give me a quick explanation of what clustering and scalable servers means? I would be most obliged, thanks
