Processor Concurrency Report
The Processor Concurrency Report graphically displays the number of processors (CPUs) within the configuration and the percentage of time that these CPUs were concurrently busy.
The Processor Concurrency Report is produced by using the CPUCON Analyzer control statement. The data for this report is obtained by using the CPU Extractor control statement.
The vertical axis of the graph represents the percentage of time that zero or more CPUs were concurrently busy; the horizontal axis represents the number of CPUs that were concurrently busy. The number of CPUs concurrently busy is represented by columns of asterisks. For example, if two processors in a system were concurrently busy 75% of the time, a column of asterisks would be printed above the number 2 on the horizontal axis and plotted up to the number 75 on the vertical axis.
A sample of the Processor Concurrency Report is shown in the following figure.

NUMBER OF CPU’S IN THE CONFIGURATION | total number of CPUs measured |
ALL CPU’S CONCURRENTLY BUSY | total percentage of time that all CPUs measured were concurrently busy |
CPU MEASURES | average percentages of time that all CPUs were not busy and multiple CPU busy percentages; these figures correspond to columns below |
SAMPLE PERCENT | axis representing percentage of time that zero or more CPUs were concurrently busy |
NUMBER OF CPU’S CONCURRENTLY BUSY | axis representing number of CPUs |
