A quick questions about clusters.
I know clusters are generally used to render complex 3D scenes and otherwise process really big tasks, but what I'm wondering, however, is if clusters can be used to assist with desktop applications (such as Internet browsing and graphics design).
I have a crapload of old computers I'm planning on putting into a cluster. Each of them is rather old, the fastest being around 700 MHz. I was planning on making a cluster to render XSI Softimage models, but I began wondering if a cluster could be set up to assist in processing all tasks and ultimately offer better performance than any one of those PCs.
I realize there would be a good deal of overhead, so I can't expect a speed demon, but would it be possible to do, and if so, would it be worthwhile? I don't expect a particularly in-depth explanation, as I'm still getting familiar with Linux and Linux networking.
