PaRSEC is a generic framework for architecture aware scheduling and management of micro-tasks on distributed many-core heterogeneous architectures. Applications we consider can be expressed as a Direct Acyclic Graph of tasks with labeled edges designating data dependencies. PaRSEC assigns computation threads to the cores, overlaps communications and computations and uses a dynamic, fully-distributed scheduler based on architectural features such as NUMA nodes and algorithmic features such as data reuse.
|
|
Several high level languages are proposed to expose the DAG from the applications. You can either build the DAG as you go, by using a mechanism called dynamic task generation (DTG), or use the JDF language to expose a compact problem-size independent format that can be queried on-demand to discover data dependencies in a totally distributed fashion.
|
|
The framework includes libraries, a runtime system, and development tools to help application developers tackle the difficult task of porting their applications to highly heterogeneous and diverse environment.
