Abstract
An option to increase performance in grand-challenge applications is overlap computation and communication. In applications developed using C and MPI, this overlapping is usually left to the programmer, but this is a tedious task. Switching from the process model to a threaded model in the parallel environment via user level threads takes advantage of the existing concurrence in an application. In this paper we expose and analyze our research group’s tomographic reconstruction software developed using AMPI, a user level thread framework that provides a solution to port legacy MPI code into a multithreaded environment where overlapping is achieved.
