S5R3 Task Crunch Time Ready Reckoner V7C

Important Points To Read

• All times are in seconds.
• Predictions are designed for data from a single machine and a given application version only.
• For data entry particularly :
  • Minumum two inputs, and generally the more the better.
  • Rigorous input checking applies to CSV input into left hand side text area/pane.
    • Three or four data values per line.
    • Values interpreted in order as FREQUENCY, SEQUENCE_NUMBER, RUNTIME and APP_VERSION respectively.
    • FREQUENCY interpreted as floating point.
    • SEQUENCE_NUMBER interpreted as integer.
    • RUNTIME interpreted as floating point.
    • if provided, APP_VERSION is accepted only if either
      • the word "mixed" ( lower case )
      • a floating point
    • Comma to separate each value.
    • No spaces within data values ( elsewhere trimming occurs ).
    • Abberant lines that do not parse as above will be discarded.
    • Each line represents a data point for analysis. There is no assumption of any ordering from one line and the next.
  • Choose a spread of task phases for a given frequency. Analysis ouput will be ascending sorted by levels of APP_VERSION, FREQUENCY and SEQUENCE_NUMBER.
  • An expected peak, average and trough runtimes plus variance and error is calculated given all qualifying tasks at each given frequency. This is subject to triage as regards fitness to predict ( complex ).
  • The right hand pane is editable. Any changes you make will be reflected when "Inputs and Outputs Summary" is selected.
  • If no error is quoted then none applies. Zero will be explicit.
• NaN in a field indicates either an bad input somewhere earlier, or an unacceptable calculation result ( various causes ).
• This an UNOFFICIAL toy. No warranties are implied or express whatsoever.
• I would be very glad to receive any & all feedback ! ;-)

Enjoy!
