Extensibility & Code Reuse

List of likely reusable components Color key

[code]: Reuse code or implementation ideas [lib]: Interact with existing library or tool

Instrumentation & measurement units (Adam, Bryan) Source instrumentation: tau_instrument [code], PDToolkit [lib]

UPC not supported with PDToolkit Binary instrumentation: DynInst [lib], DPCL [lib], ATOM [lib], Pin [lib]

Cray not supported with DynInst DPCL only works with AIX and Linux (based on DynInst) ATOM only on Tru64 Pin only on IA32/IA64 Linux, very new (based on DynInst)

Hardware counters: PAPI [lib], PCL [lib] General trace and profile routines: TAU [code], EPILOG & EARL from

KOJAK [lib/code]

3

Extensibility & Code Reuse (2)

Analysis unit (Hung-Hsun) Source code correlation from wrapper libraries: HPCToolkit

[code], mpiP [code] Pattern matching for bottleneck identification: EXPERT

from KOJAK [lib] Presentation unit (Hans)

Trace visualization: Jumpshot [code/lib], Intel Trace Analyzer or VampirNG using libvtf [lib]

Profile visualization: CUBE from KOJAK [lib], Paraprof from TAU [code/lib]

Source code viewer: ToolGear [code/lib], HPCToolkit [code]

Tasks: I & M Unit: Adam and Bryan PUPC, PDToolkit vs. writing parser from scratch (4 weeks)

Also time for PUPC work Need parser for source instrumentation for PUPC PDToolkit might work for SHMEM code, possibly with UPC if we use macro tricks

DynInst (2 weeks) Determine how difficult it is to use DynInst “Advanced” feature, but should know how hard it is to use DynInst for planning purposes

PAPI vs. PCL (2 weeks) Find which is better (requires less kernel patching) and has better platform support Find out how the best one works and how to use API

Trace file format and indexing (4 weeks) Re-use TAU or KOJAK code, or write trace write/read library from scratch? Investigate indexing options Work with Hung-Hsun and Hans to find what type of indexing would be useful for analysis and

presentation Search for static binary instrumentation toolkits (1 week)

Static binary instrumentation might be more flexible than dynamic for instrumenting executables Preliminary search has turned up no existing cross-platform static instrumentation kits

5

Tasks: A Unit: Hung-Hsun

Literature search on analysis See if we can use EXPERT / APART stuff …

6

Tasks: P Unit: Hans Examine code from existing projects (4 weeks)

Only look at presentation parts (ignore measurement, source correlation, PAPI, etc etc)

Trace tools (2 weeks) Jumpshot libvtf3 for writing Vampir traces

Profile tools (2 week) Toolgear CUBE Paraprof HPCToolkit

Experiment with writing graphical programs (5 weeks) General graphics tutorials/concepts (1 week) Java, other languages/platforms as necessary Find existing graphics toolkits to help

Start designing preliminary user interface (3 weeks) Perform alongside graphical coding task (see Gantt chart) so ideas can be tested
