|
|
"""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.
