An Integrated Framework for Performance Engineering and Resource-Aware Compilation

NSF EIA 99-75019

About the project

Next generation parallel and distributed computing systems have the potential to provide greatly increased capabilities and performance. This potential has enabled the development of increasingly complex scientific and commercial applications, which have stringent performance requirements, must be extensible, and must scale well as problem size and/or desired degree of parallelism increases. The significant development costs, maintenance costs, and performance requirements of these applications call for a comprehensive and integrated approach to application composition and development, system and application modeling and evaluation, performance characterization, compiler optimization, and low-overhead runtime support. Achieving these capabilities will require fundamental advances in 1) methods for hierarchical, multi-language modeling, simulation, and evaluation, and 2) techniques for adaptive, resource-aware compilation and runtime support. In this project, we will take a systematic and synergetic approach to making these advances, and incorporate them in an integrated performance engineering framework and resource-aware compilation and runtime system. In addition, we will demonstrate the use of the integrated framework/system via application to several important parallel and distributed multimedia, video database, and computer vision applications.

With respect to the first project objective, we will develop a performance engineering framework for complete distributed and parallel computing systems, accounting for system components including the application software itself, the operating system, and the underlying computing and communication hardware. The framework will be usable in a stand-alone fashion, or in conjunction with the compilation and runtime support environment after an application and hardware have been developed, to guide the compiler and runtime support system in making decisions concerning specific optimizations and resource allocations. It will provide a means by which multiple, heterogeneous models can be composed together, each representing a different module (software or hardware), component, or view of the system. The composition techniques developed will permit the models to interact with one another by sharing state, events, or results, and will be scalable, in the sense that the solution of the entire model will be possible at a cost lower than for an equivalent unstructured model. Multiple modeling languages will be developed, as well as methods to combine models at different levels of resolution. Finally, we will develop model solution methods, including both simulation and analysis, that are efficient, and permit the solution of complete models of complex computing and communication systems, and the applications executing on such systems.

The second project objective is the design of resource-aware algorithms for program transformations, code optimization, and scheduling for multithreaded and ILP architectures; the development of a multilingual resource-aware optimizing compiler; and the development of compiler-generated, application-specific runtime support for high-performance parallel and distributed computer systems. Our approach enables low-overhead, adaptive runtime support to be generated by the compiler and embedded in user code. By using information about application internals (derived by the compiler through analysis and/or user assertions), and knowledge of the target architecture(s) of hierarchical distributed systems, we will produce executable code that scales dynamically and is "responsive" to reconfigurations in the type and number of system resources. Resource-awareness is introduced at each level of the compilation and runtime support phases, and is achieved via resource modeling languages that serve both the compilation and the performance engineering framework.

The modeling, compilation, and runtime techniques summarized above will be synergistically combined to obtain an integrated compiler/runtime/performance engineering framework. To demonstrate the utility of our approach, we will apply the developed performance engineering framework, resource-aware compiler, and runtime environment to multiple distributed applications, including video-filtering, video-indexing, and face-tracking applications that are of significant and increasing importance to the scientific and commercial worlds. These applications rely on computationally demanding algorithms, which are prototypical of many integer and floating-point applications, and can both validate the usefulness of the developed framework and benefit from its use.
