N-Body Simulation and Collective Communication (SC '08 Education Program's Workshop on Parallel & Cluster Computing)
(2008-08-10)
An N-body problem is a problem involving N “bodies” – that is, particles (e.g., stars, atoms) – each of which applies a force to all of the others.
For example, if you have N stars, then each of the N stars exerts a ...

An application is known as embarrassingly parallel if its parallel implementation:
can straightforwardly be broken up into roughly equal amounts of work per processor, AND
has minimal parallel overhead (e.g., communication ...
