Clustering is a method of connecting multiple computers (called nodes) together to form one large system dedicated to a particular task or series of tasks.
we have to distinguish between two kind of clusters:
computational OR high availability systems.
In our laboratory we are interested on the former one:
Computational clusters are designed to do the complex computational
calculations of supercompuetrs. A quality high speed netwrok is an important feature
of computational clusters. The high speed network allows nodes to communicate quickly and finish calculations in less time.
