PSM Computations

All of the features in the PSM interface are designed to support the most important features, those of computation:

Method Description
Partition (^A) Sort the problem to expose blocks
Tear & Show Primary Circuit   (^T) Analyze a block to see principal circuit and show the tearing advice window
Show Impacted Rows (^I) Impact shows the rows that have the selected rows as a predecessor.
Show Notified Rows (^W) Notify shows the rows that as a result of the selected rows have ALL of their predecessors satisfied.
Show Bands of Parallel Items (^U) Shows bands of parallel items. With in each band each of the tasks can be done at the same time. e.g. each row in the band has a predecessors in the prior band but none in its band.


  • By using the combination of Control + Click rows can be selected to participate in computations. Notice that selecting and excluding rows does not effect partitioning or tearing.
  • Repeated control clicks cycle between: 
        Selected (Default: Blue)
        Excluded (Default: Purple)
        Not Selected (Default: Grey)
  • As the result of computation, rows can be turned to the computed color (Default: Green)
Persistence and row marking
  • F11: Edit/Deselect All can be used to remove all selections. This does not effect rows persisted to the database.
  • Shift+F11: Persist (remember) all the selected rows to the database.
  • Control+F11: Clear persistence of all rows from the database
