Description

Legion is a data-centric parallel programming system for writing
portable high performance programs targeted at distributed heterogeneous
architectures. Legion presents abstractions which allow programmers to
describe properties of program data (e.g. independence, locality). By
making the Legion programming system aware of the structure of program
data, it can automate many of the tedious tasks programmers currently
face, including correctly extracting task- and data-level parallelism
and moving data around complex memory hierarchies. A novel mapping
interface provides explicit programmer controlled placement of data in
the memory hierarchy and assignment of tasks to processors in a way that
is orthogonal to correctness, thereby enabling easy porting and tuning
of Legion applications to new architectures.
