Assessment and Prog. Development Tools [ECRC,UPM]

• Achievements:
  • Designed and implemented a parallel trace visualization tool Parsee which: [ECRC]
    • automatically transforms user progs. to generate a trace file
    • analyses large trace files efficiently (linear time)
    • abstracts away all low-level details of the program trace
    • produces a variety of static color pictures which are directly useful to the application programmer
    • is scalable to any number of processors
    • is scalable in time, allowing zoom-in and -out
    • successfully applied to problems s.a. aircraft assembly line planning, computational biology and graph coloring

  • Improved a tool (VisAndOr) and developed another (IDRA) which: [UPM]
    • give synthetic and intuitive data on program behavior
    • help the application programmer to understand the performance of the code
    • are complementary to the ECRC tools (and the traces can also be used by Parsee)
    • are used in other systems (e.g., in MUSE)
    • VisAndOr: time-oriented schematic view of the parallel execution, by means of traces collected at run-time
    • IDRA: analysis of VisAndOr traces to uncover potential parallelism not exploited in actual executions
