The SuperCodelet architecture

BSTRACTThis paper proposes a hierarchical organization of a distributed, parallel and heterogeneous computer system based on the Sequential Codelet Model. It defines a Hybrid Dataflow/von Neumann architecture which enables parallel execution of sequentially defined Codelets at a multi-hierarchical organization of the system. This architecture takes advantage of instruction level parallelism techniques based on dataflow analysis, allowing implicit parallel execution of code. We present the SuperCodelet Architecture. We describe the program execution model and its corresponding programming model, and provide an evaluation of its program execution model through a prototype emulator based on commodity computer systems.
