This paper describes a formal design method which can be used to synthesize optimal heterogeneous systems for given applications. The method is quite general and we show how to apply it to a specific style of designs. The method involves creation of a Mixed Integer-Linear Programming (MILP) model and solution of the model. Several experiments and tradeon studies were performed using the method. These results indicate that the method can be a useful tool in designing heterogeneous systems.","PeriodicalId":201815,"journal":{"name":"Proceedings.

The challenge is to partition a functional program (or a process) into appropriately-sized sub-processes to make sure that the computation time of the local sub-process is at least greater than the communication overheads involved in sending other sub-processes for remote evaluation. It is shown how some parallel programs can be run more efficiently with the prior information of time complexities (in big-0 notation) and relative time complexities of its sub-expressions with the help of some practical examples on the larger-grain distributed multiprocessor machine LAGER.","PeriodicalId":201815,"journal":{"name":"Proceedings.

Superconcurrency as a form of distributed heterogeneous supercomputing is an approach for matching and managing an optimally configured suite of super-speed machines to minimize the execution time on a given task. The approach performs best when the computational requirements for a given set of tasks are diverse. A supercomputing application task is decomposed into a collection of code segments, where the processing requirement is homogeneous in each code segment. The optimal selection theory has been proposed to choose the optimal configuration of machines for a supercomputing problem. This technique is based on code projiling and analytical benchmarking. Here, the previously presented optimal selection theory approach is augmented in two ways: the performance of code segments on non-optimal machine choices is incorporated and non-uniform &compositions of code segments are considered.","PeriodicalId":201815,"journal":{"name":"Proceedings.
