Abstract

This paper presents an overview of the eMERGE system, a service-oriented system for medical image reconstruction on parallel computers. Within the eMERGE system, parallel image reconstruction codes running on SMP clusters or other parallel machines may be exposed as Jini services, as Web Services, or as OGSA services and accessed over the Internet by means of a browser-based GUI. The system provides support for dynamic service management, service selection and monitoring. We describe the parallelization of a fully 3D iterative image reconstruction code using a combination of MPI and OpenMP, discuss the major design and implementation issues of the various service types supported by our system, and present experimental results comparing the performance of RMI-based to SOAP-based image data transfers.
