  1. Summertime FunEveryone loves performance Shirley Browne, George Ho, Jeff Horner, Kevin London, Philip Mucci, John Thurman

  2. Projects • PerfAPI • Cache Simulator • DOD Performance Optimization • Rice/PET Collaboration • Benchmarking • HPD implementation • Graduation

  3. PerfAPI • Research gathered on the following platforms • Sun Ultra • Pentium Pro/II • IBM Power Series • MIPS R10000 • DEC Alpha, Cray T3E • Cray T90/SV1

  4. PerfAPI • Standard API to access hardware performance counters • Standard set of definitions for performance metrics • Resulting in: • Data for performance tool developers • Data for tuning and evaluating applications • Portable performance tools for every major platform

  5. PerfAPI Research on the user’s needs through • Mailing list • Web page http://www.cs.utk.edu/~mucci/pdsa • Collaboration with existing researchers • Vendors (Sun, Cray, Digital, SGI) • SPDT98/SC98 poster

  6. PerfAPI - Coming this fall • Draft API by 8/31 released to mailing list • 9/31 revisions incorporated into a tech report • 10/31 implementations for MIPS and Ultra • 11/31 Implementations for IBM and Intel • 12/31 Implementations for Alpha • 12/31 Portable hardware counter based prof

  7. Cache Simulator • Motivated by the need for information correlated with the source code and run-time reference patterns • Redesign into object oriented structure and raw output format • Statistical reduction techniques • GUI design • Parser design

  8. Cache Simulator • GUI written in Java • Parsers written using Octave from Edinburg. (?) • Tool will allow browsing and instrumentation of source • Reporting will be done with perl scripts • Money from Sandia pending • Conflict matrix adopted by IBM/Watson

  9. DOD Performance Optimization • Optimization Tutorial and Poster at User’s Group Meeting • Visit to ASC to help scalability of Cobalt • Putting together a performance team with a suite of in-house tools. • Meeting at Rice to direct a possible collaboration with Rice on run-time data collection for optimization.

  10. DOD Performance Optimization • Upcoming tutorial at ARL 2 day + 1 day workshop • Speaking at annual ARL UGM • Work with Cobalt, MAGI, GAMESS, HELIX • Developers reluctance! • Lack of tools! • PET lead?

  11. DOE Benchmarking • Attended Weather/Climate modeling conference in June. • Need for standardized benchmarks • Complete lack of understanding of performance • Opportunity for UT involvement • Meeting in September at NCAR • Virgin territory?

  12. Benchmarking • Modifications to 3 benchmarks plus a new one. • MPBench • BLASBench • CacheBench • ClockBench • Standardized options and graph generation • Integration into a Low-Level suite

  13. Benchmarking MSRC Machines • Completed benchmark runs for BlasBench, CacheBench and MPBench on all the MSRC platforms. • In the Process of finishing Dedicated Runs of the ParkBench Suite. • Made graphs of the results and added them into the BenchRib repository.

  14. MPBench • Add alltoall test • Dynamic memory allocation • NUMA measurement • Cache flushing code

  15. Benchmarking • BLASbench • Addition of solvers • CacheBench • Latency benchmark • ClockBench • Timer accuracy

  16. HPD Implementation • Elimination of Dolphin as a solution provider • Received front end parser • Building distributed Perl framework • DBX/GDB as backends
