Intro to PGAS - UPC and CAF - and Hybrid for Multicore Programming

SESSION: Intro to PGAS - UPC and CAF - and Hybrid for Multicore Programming

EVENT TYPE: Tutorials

TIME: 8:30AM - 5:00PM

Presenter(s):Alice Koniges, Katherine Yelick, Rolf Rabenseifner, Reinhold Bader, David Eder

ROOM:251-D

ABSTRACT:
PGAS (Partitioned Global Address Space) languages offer both an alternative to traditional parallelization approaches (MPI and OpenMP), and the possibility of improved performance on heterogeneous and modern architectures. In this tutorial we cover general PGAS concepts and give an in depth presentation of two commonly used PGAS languages, Coarray Fortran (CAF) and Unified Parallel C (UPC). Hands-on exercises to illustrate important concepts are interspersed with the lectures. Basic PGAS features, syntax for data distribution, intrinsic functions and synchronization primitives are discussed. Advanced topics include optimization and correctness checking of PGAS codes with an emphasis on emerging and planned PGAS language extensions targeted at scalability and usability improvement. A section on migration of MPI codes using performance improvements from both CAF and UPC is given in a hybrid programming section. Longer examples, tools and performance data on the latest petascale systems round out the presentations.
