Abstract
Programmers tend to think of parallel programming as a problem of
dividing up computation, but often the most important decisions involve the
partitioning, placement and movement of data. As machines become more
complex and hierarchical, describing what to do with the data is increasingly
a first-class programming concern.
Legion is a programming model and runtime system for describing hierarchical
organizations of both data and computation at an abstract level. This talk
will present the design of Legion and its rationale and discuss recent work developing
high-productivity libraries using Legion’s capabilities.
