1 CCA Forum Fall Meeting120-22 October 20081 CCA Common Component Architecture Update on TASCS Component Technology Initiatives CCA Forum Fall Meeting 20-22 October 2008

2 CCA Forum Fall Meeting220-22 October 2008 CCA Common Component Architecture Support for Emerging HPC Hardware and Software Paradigms Overall Goal: Enable effective use of CCA on emerging HPC architectures Recent Activities and Plans –CCA on Heterogenous Architectures helps with portability and management of software modules executing on hardware accelerators (FPGA, IBM Cell, NVDIA Tesla etc) Inverse Hadamard transform deconvolution: I. Gorton, D. Chavarría-Miranda, M. Krishnan, and J. Nieplocha, Simulating Data Processing for an Advanced Ion Mobility Mass Spectrometer, in Proceedings of HPRCTA’07. D. Chavarría-Miranda, J. Nieplocha, and I. Gorton, Hardware-accelerated Components for Hybrid Computing Systems, in Proceedings of CBHPC (Component-Based High Performance Computing), 2008. –High Performance Event Service provides efficient and scalable implementation of CCA Event Service Provides notification, data delivery, coordination between components Event Service is used to distribute work and coordinate execution between CPU-only nodes and nodes with attached FPGAs on an HPC system I. Gorton, D. Chavarría-Miranda, and J. Nieplocha, Design and Implementation of a High-Performance CCA Event Service, to appear in Concurrency--Practice and Experience, 2008. Working on scalability issues and full SIDL-compatible implementation –Multiple-Component-Multiple-Data (MCMD) CCA Technology enables componentization of apps based on multiple levels of parallelism with focus on massively parallel systems. CCA Team specs and implementation available, engaging with subsurface applications MCMD implementation for subsurface simulations (PNNL) –Parameter studies using multiple instances of parallel STOMP components for simulating subsurface flow and transport MCMD framework implementation underway for SWIM (Python component framework) at ORNL Observation Parameters STOMP U-CODE Stomp/UCODE MCMD Driver STOMP TeamService Team ProcessID

3 CCA Forum Fall Meeting320-22 October 2008 CCA Common Component Architecture Software Quality and Verification Overall Goal: Extend component interface definitions with semantic annotations that can be verified/enforced at composition or run time (contracts). Recent Activities –Babel release 1.4.0 demonstrates contract enforcement across languages C client  C, C++, F77, F90, Java, and Python implementations C++ client  C, C++, F77, F90, Java, and Python implementations –Client-side support for setting contract policies Modified compiler for Fortran, Java, and Python Currently debugging build-related issue with client-side support for setting contract policies in remaining language wrappers (Fortran name mangling issue) –Regression tests: Python tests debugging pending resolution of build issue Plans –Near-term: Resolve Fortran compilation/build problem Debug python regression tests Add client-side regression test drivers for (in order): Fortran and Java Resume updating the Babel User’s Guide –CQoS collaboration: leverage new interface contract enforcement features –Enhance Babel regression tests to exercise more interface contract features (e.g., invariants, more/new built-in methods)

4 CCA Forum Fall Meeting420-22 October 2008 CCA Common Component Architecture Computational Quality of Service Overall Goal: Develop infrastructure for dynamic component adaptivity, i.e., composing, substituting, and reconfiguring running component applications in response to changing conditions –Performance, accuracy, mathematical consistency, reliability, etc. Recent Activities and Plans –Analysis and Control infrastructure: Enhancements to PerfExplorer CCA component and CQoS database component A Component Infrastructure for Performance and Power Modeling of Parallel Scientific Applications, V. Bui, B. Norris, K. Huck, L. C. McInnes, L. Li, O. Hernandez, and B. Chapman, Proceedings of Component-Based High Performance Computing Workshop, October 14-17, 2008, Karlsruhe, Germany ACM, 2008, in press. –Combustion: Ongoing work on CQoS use with metapartitioner –Quantum chemistry: Work on chem-CQoS demo and poster for SC08 http://wiki.mcs.anl.gov/cqos/index.php/Qua ntum_Chemistry_CQoS_Activities Joe Kenny (SNL), Alexander Gaenko, Heather Neltzoff, Meng-Shiou Wu (Ames), Li Li, Lois McInnes, Boyana Norris (ANL), Kevin Huck, Allen Malony (U of Oregon) Hands-on coding session on October 20, Chicago Chem-CQoS diagram
