Monte Carlo Simulation (SC '08 Education Program's Workshop on Parallel & Cluster Computing)
(2008-08-10)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 ... -
MPI Introduction (SC '08 Education Program's Workshop on Parallel & Cluster Computing)
(2008-08-10)WHAT IS MPI? The Message-Passing Interface (MPI) is a standard for expressing distributed parallelism via message passing. MPI consists of a header file, a library of routines and a runtime environment. When you compile ... -

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 ... -
NHC Node Health Check
(2015-05-18)Why NHC? Currently no standard -- Most sites use custom, home-grown scripts Often site-specific Usually lacking portability Unreliable execution, reporting, parent performance Need a simple, robust ... -
