SPECjvm2008 Evaluation

Preconditions/Legacy

• Find/document legacy code (scattered over FileShare, ByCounter, ByCounterEvaluation, BySuite.ByPred, Klaus' Sachen)
• get Klaus' R "connector" for computing learned mathematical expressions by providing them with input (e.g. file size for FileShare)

Process

• re-create from emails?

Subject

SPECjvm2008.Compress

• document changes to source code
• document instrumented methods: size, invariance, frequency, call graph
• document input files

SPECjvm2008.SciMark

• FFT
  • nice parametric dependency for internal actions
  • only few external dependencies (random vector + result check)

SPECjvm2008.XML ???

• Validation
  • spec.benchmarks.xml.validation:
    • executeWorkload() / doValidationTests()
      • external dependencies
      • Loops
      • Parametric dependencies: files size

Learning of Dependencies

• Klaus

Measurement

• Michael misst SPECjvm2008.compress bis zum 18.5. (möglichst automatisiert), Auswertungen:
  1. ns per byte, depending on file size
  2. normal vs. -Xint vs. -server

Prediction

• Variant 1: using Excel or Michael's Java-Code
  • Michael automatisiert das bis 18.5.
• Variant 2: using RDSEFF from "PCM 4.0" (aka DA Micha Hauck)
  • Klaus muss StoExe/RDSEFFs automatisch

Evaluation of Result (Stats)

• (optional) Michael: Excel (Visualierung, Ausreißßer)
