Abstract
This paper presents a publish/subscribe based asynchronous remote method invocation framework (PARMI) aiming to improve performance and programming flexibility. PARMI enables high-performance communication among heterogeneous distributed processors. Based on publish/subscribe paradigm, PARMI realizes asynchronous communication and computation by decoupling objects in space and time. The design of PARMI is motivated by the needs of scientific applications that adopt asynchronous iterative algorithms. An example scientific application based on the Jacobi iteration numerical method is developed to verify our model and evaluate the system performance. Extensive experimental results on up to 60 processors demonstrate the significant communication speedup using asynchronous computation and communication technique based on the PARMI framework compared to a baseline scheme using synchronous iteration and communication.
