AbstractNext generation processors attain better performance than existing microprocessors because the abstraction layers better expose the underlying VLSI resources (transistors, wires, pins, ...) and constraints (e.g., wire delay, power, ...). However, the management of these resources and constraints requires the development of more sophisticated hardware and software mechanisms, both to improve efficiency and to ease programmer burden. MaXentric believes the largest advances in the next decade of computer architecture will center around these mechanisms. Our vision is a tool chain of software support that helps the user parallelize applications from choosing the appropriate architecture to analyzing and profiling the application for potential re-organization and improvement. We propose one piece of this chain, codenamed PAMM (Problem-Architecture Mapping for Multi-core) that helps the user select an architecture for a given application and to make optimizations based on that architecture. During Phase I, MaXentric demonstrated the feasibility of the approach. During Phase II, the technical team will build a PAMM prototype for Phase III commercialization. BENEFIT: Moore''''s law has provided computer architects with a wealth of on chip resources. Next generation processors reflect the latest innovative responses to advances in integration technologies. However, from a programmer''''s perspective, parallelization is still a difficult task with a lack of tool chain support and a small community. Tools developed under this SBIR project will be equipped to support high performance application development projects in the commercial and defense realms. Value added to a project has two flavors. Firstly, these tools will aid in the acquisition of computing resources, allowing project managers to select hardware that best fits their applications and consequently slashing unnecessary costs. Secondly, the tools will assist the programmers in the project as they build their applications, decide how to map them to architectures, and optimize their code for higher performance. Both the defense and commercial sectors are interested in computationally intensive problems that could be accelerated by a well chosen next generation processor.
