CCA Forum Winter Meeting January 2007 CCA Common Component Architecture Support for Emerging HPC Hardware and Software Paradigms Overall goal: Assure that the CCA can be used effectively on emerging architectures Primary focus areas (PNNL, ORNL) –Heterogenous platforms that combine specialized h/w accelerators with general purpose processors e.g., IBM Roadrunner, Cray XD1 or Cascade system –Multiple-Component-Multiple-Data CCA model that enables componentization of apps based on multiple levels of parallelism especially on massively parallel systems Mini-Workshop held 24 January, 2007 Secondary focus area is Fault Tolerance, with ORNL connecting us to the Argonne-led Fault Tolerance project –Level of effort reduced due to budget cuts

CCA Forum Winter Meeting January 2007 CCA Common Component Architecture CCA on Heterogenous Systems Application accelerator services to accelerate application performance on hybrid or heterogeneous architectures PNNL team working with proteomics application Polygraph that uses FPGA computes a “spectral fingerprints” Want to be able build CCA reusable FPGA-accelerated components using that encapsulate common scientific algorithms Event service is essential for linking components on general purpose CPU and FPGA Prototype HPC implementation (Steve Parker proposal) done for the Cray XD1 HPC Computers with hardware accelerators connected via a high-speed interconnect Initial focus on systems with Field Programmable Gate Array (FPGA) accelerators

CCA Forum Winter Meeting January 2007 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) Current focus: Integrating contract enforcement features. Goals: –Eliminate C binding dependencies –Reduce client-side instrumentation burden Especially for programs using multiple (annotated) classes –Eliminate implementation burden on server-side March 2007 –Integration of new capabilities into main Babel repository –IOR and C bindings TOPS Solver Components and TAO optimization component examples will also be used in enforcement experiments milestone in mid-March.

CCA Forum Winter Meeting January 2007 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. CQoS s ubgroup meeting on 24 January, 2007 –Year-1 deliverables in progress Identify requirements of motivating applications Define metrics, perform base experiments Implement performance database query and management components –Summary of recent work: Details in cvs repository: cca2-docs/2007/jan07-cqos Initial motivating applications: –Quantum chemistry: Joe and Meng-Shiou –Combustion: Jaideep and Rob –Accelerators: Doug and Lois CQoS Infrastructure: –Analysis (when to change): Sameer and Allen –Semantics: Tammy –Control (what to change): Boyana and Jaideep

CCA Forum Winter Meeting January 2007 CCA Common Component Architecture CQoS: Near-Term Activities Build testbed of simplified CQoS example problems –Goal: Enable CQoS infrastructure development and testing without requiring complete combustion/chemistry/accelerator applications –Initial plans for contents: Parallel 2D regular mesh with chemistry/physics varying in 2 subdomains: Rob TOPS linear solver components: Make initial algorithmic choices based on matrix metadata (using Eijkhout’s Anamod); later incorporate adaptivity in nonlinear problems Additional simplifications or subparts of the motivating combustion/chemistry/accelerator simulations Establish a Wiki to facilitate subgroup interactions –Question for everyone: Is there a preferred CCA wiki approach for working groups? Likely wikis would be useful for a variety of TASCS subgroups …

CCA Forum Winter Meeting January 2007 CCA Common Component Architecture Toolkit Component Providers - Now is the time to contribute Components should build against a recent Sumo –Our users will install the Sumo Distribution tarball should install in the canonical places – Send a copy of the tarball to –Rob will create a toolkit “Sumo” from selected components (I.e. components that build en masse) Come to the BOF tomorrow

CCA Forum Winter Meeting January 2007 CCA Common Component Architecture Introducing Bocca, a Rails-like templating system for CCA Wael, Boyana, Ben and Rob have been working on this. Creates an entire project complete with build tree –Create components that build and load out-of-the-box And incidently do nothing Allows users to start with working components that can be evolved into something useful. –Lowers the barrier to learning using CCA
