Linux Create a working Linux cluster from many separate pieces of hardware and software. Part 1 of the series provides detailed instructions on setting up the hardware for the cluster. Part 2 describes configuring the management server and installing the nodes in the cluster. This provides an easy way to get started with large Linux clusters.

Quite technical. Anybody have ideas for stuff to do with clusters? Running one at work or home would be cool, but of course, you have to be a data-crunching scientist or company to justify one.

It depends on the clustering technology. If you use a MOSIX based system (which is what I would recomend, if you are not into scientific number crunching alone), you can load-balance seperate tasks quite nicely across a even heterogenous cluster (I have installed one for my sister who is not really a number cruncher, for parallising cd ripping to ogg files or render analog-to-digital videos from her camcorder at a process level. Very effective, even though the cluster employs several older machines). Mosix clusters are also known to work with scientific/mathematical software like (IIRC, please correct me if I'm wrong) octave or R.

I guess you could call me a professional number cruncher (computational physicist) and we use MPI (and sometimes even PVM) to parallise our integral equation solvers at code level (e.g. the programm has to implement the parallising structures), mostly due to the fact, that the equations kernels would never fit into a single machines memory.

If you programm in C/Fortran/C++ or Java, then playing with MPI to parallise existing code can be interesting and entertaining

EDIT: Some pointers for usage scenarios with openMosix, perhaps this gives you a better estimation of what general purpose applications can benefit from clusters.

I have currently no access to my link collection, perhaps this three urls help a little
