As you select events in this manner, you will have your own schedule to guide you through the week.

You can also create your personal schedule on the SC11 app (Boopsie) on your smartphone. Simply select a session you want to attend and "add" it to your plan.

SESSION: PARALLEL: Parallel Paradigms and Decompositions

EVENT TYPE: Education

TIME: 10:30AM - 12:00PM

SESSION CHAIR: Charles Peck

Presenter(s):Charlie Peck, Thomas Murphy, Daniel Ernst, Henry Neeman, Daniel Ernst

ROOM:WSCC 611/612/613/614

ABSTRACT:
This session focuses on various kinds of parallelism, motivated by example application types. Topics include: Monte Carlo simulation to illustrate client-server (the concept of embarrassingly parallel or loosely coupled computing, Monte Carlo methods in lay terms, high energy physics as a motivating example, parallelization of Monte Carlo); N-body methods to illustrate task parallelism (N-body problems, 1-, 2- and 3-body problems, big-O notation for non-computer scientists, spatial vs temporal complexity, force calculations, parallelizing force calculations, data parallelism vs task parallelism, reductions, collective communications); transport problems to illustrate data parallelism (Riemann sums, mesh discretizations, finite difference method, Navier-Stokes equation, ghost boundary zones, data decomposition, Cartesian geometries, use of send/receive buffers). Prerequisite: "MPI Collective Communication" session or equivalent.
