This quarter's parallel programming seminar will focus on reviewing Chapel, a new parallel programming language being developed in Seattle by Cray Inc. Cray is undertaking Chapel as part of its entry in the government's High Productivity Computing Systems program (HPCS) which has the goal of raising user productivity on high-end parallel systems by 10x for the year 2010. Chapel aims to support general parallel programming including data parallelism (based on features developed at UW in the ZPL programming langauge), task parallelism, and nested parallelism. Chapel also strives to narrow the gap that currently exists between high-end and mainstream languages by supporting OOP, generics, and type inference. For more information on Chapel, please refer to: http://chapel.cs.washington.edu
The main goals of this seminar are to introduce the UW community to the Chapel language, to solicit feedback on the language from the academic community, and to identify opportunities for future collaboration. The seminar will be led by members of the Chapel team from Cray, and will be loosely structured around a set of language features each week followed by open discussion. The draft Chapel language specification will serve as the basis for readings.
This seminar is targeted toward those whose interests include programming languages, compilers, parallel programming, multicore programming, scientific computation, and tools/programming environments. This seminar has the potential to lead to quals projects for students interested in the topics covered.
