Programmable Marker Lights (pmarray) - IBM SP execution analysis

abstract

The programmable marker lights are a simple method for a user to watch
the progress of a calculation on the IBM SP. They appear as an array of
colored squares (lights) in a separate X window when one issues the
pmarray command. The number of rows in the array is equal to the number
of tasks that will execute and the number of columns is determined by the
user through an environment variable. The color of each light is changed by
a subroutine that one can insert at strategic places in the code. There is an
optional message field in the subroutine call which allows for text
messages to appear in a box next to the array of lights.
