Programming Models for High Performance Scientific Computing

Jeff Hammond - ALCF
Seminar

A Programming model is the high-level structure within which an algorithm is implemented. The complexity of the programming model required for a given application depends greatly on the type of parallelism to be expressed. In the first part of this talk, Jeff will highlight some of the most common programming models (e.g. mast-worker) and describe their implementation within MPI. The second part will focus on asynchronous programming models using one-sided communication and the utility of this model within application codes in biology and chemistry.
