  1. Synthesizing Parallel Programming Models for Asymmetric Multi-core Systems Dimitris Nikolopoulos, Kirk Cameron Center for High-End Computing Systems Department of Computer Science Virginia Tech {dsn,cameron}@cs.vt.edu

  2. Asymmetric Multi-Core Systems • Potential for data-intensive applications • Multiple dimensions of parallelism • Heterogeneity, application-specific accelerators • Ample memory bandwidth • Flexibility via delegating control to software • Limitations • Programming models ignore polymorphic parallelism • Runtime systems ignore polymorphic parallelism

  3. Contributions • Polymorphic parallelism on the Cell BE • Event-driven scheduling • Unification of task, data, pipeline parallel execution • Integration of DMA and communication parallelism • Runtime performance prediction • Model of multi-grain concurrency • Model-driven adaptation in the runtime system • Cell system software modules • EDTLP, MMGP

  4. Results
