Upshot
Parallel Program Visualization Tool

Upshot was written by Ed Karrels while a student at Argonne National
Laboratory, under the direction of Ewing Lusk.  Additional direction and
development were performed by William Gropp.

Upshot is a Tcl/Tk program written for visualizing Alog, and PICL
format logfiles.

SETUP
  1.  Build Tcl/Tk, including the 'wish' executable.  Upshot requires
      Tk version 3.3 or above.  Tcl and Tk can be acquired via anonymous
      ftp from harbor.ecn.purdue.edu in /pub/tcl/sprite-mirror as
      tk3.6.tar.Z and tcl7.3.tar.Z.  Tk version 4 (incompatible with 
      version 3) can be used.

  2.  Modify the first line in profiling/upshot/bin/upshot to point to the
      wish executable:
      e.g.    #!/usr/local/tcl/bin/upshot -f

  3.  Modify line 7 (set bitmapdir ...) to point to the directory with
      all the bitmaps available to Upshot.  These are by default in the
      same directory as the upshot source code.
      e.g.    set bitmapdir /usr/local/mpi/profiling/upshot/bin

  4.  Modify line 12 (set defaultfile ...) to point to whatever file
      you wish Upshot to put/get settings into/from.

RUNNING

  Run profiling/upshot/bin/upshot.  It is a Tcl/Tk script, and with the
  first line (#!/...wish -f) it automatically runs itself through 'wish',
  the Tcl/Tk windowing shell.  I've heard that some shells don't like
  the #!/... notation.  If your machine is one of these, please let me
  know.  The program can still be run, but it will have to be run through
  the wish interpreter manually.  For example:

    wish -f profiling/upshot/bin/upshot

  Or, of course, a quick script can be written to do this.

  Using the program is (hopefully) mostly intuitive, so I'll just go over
  a few brief points.

  From the main window:
    "Select Logfile" brings up a dialog box for selecting a different logfile.
    "Setup" loads the select logfile and displays it.
    "Options" brings up a dialog box for setting a few program options.
    "Quit" closes Upshot.

  Select Logfile:
    All directories in the current directory are listed, as well as all files
    that match the glob-style pattern in the 'Pattern:' entry field.
    Click on a directory or file name to select it; double click on or click
    on and hit 'OK' to change to the directory or select the file and
    banish the dialog box.  When the file is clicked on, the file format
    will be set automatically.  (Alog for *.log files, Picl for *.trf files,
    Alog for anything else)  If the automatic format is incorrect, click on
    the correct format.  Click 'OK' to accept the selection and close the
    dialog box.  Click 'cancel' to close the dialog box and ignore the selected
    file.

  Setup button - open the file:
    Clicking 'Setup' will load the logfile.  This may take a while, depending
    on the size of the logfile, so a percent-done meter is displayed.  When
    Upshot is finished loading the file, it displays the entire file in one
    view.  Horizontal and vertical zoom buttons do what they say.  To set
    the zoom point (the point of display that is stationary while the rest
    expands or contracts around it), third-button click on the point of the
    display desired.  To drag the canvas around, second-button click 'n drag
    the display.  All mouse drag motion will be magnified 10x in the
    displacement of the display.  'Reset' resets the display back to the
    original view and adjust to fit the window if it has been resized.
    Click on a state name or color box in the legend (at the top of the
    display window) to get a distribution graph of the length (in sec.)
    of all instances of that state.  The beginning and ending ranges of
    the viewed portion can be adjusted to look closer at a certain range.

  More than one logfile, or multiple copies of the same logfile can be open
  at a time.  Just select another logfile in the initial window and hit
  'Setup' again.

  Some sample logfiles are in the profiling/upshot/logfiles directory.

BUGS
  Something is goofy with the legend.  It looks fine when printed out, but
  on the legend items are jumbled sometimes.  I've found they sort themselves
  out after a few redraws.

  Stipple fill patterns get a little chopped on the left side on some
  items when they are printed.

TODO
  Rewrite as much as possible in C to speed it up.
  Add translator for the new format of PICL files.
  The user interface on the state length distribution histogram isn't that
    great.
  This distribution histograms are pretty slow, rewrite this in C.
