Roopalini- 
As a starting point, you can examine ResUsage: 
Calculating parallel efficiency using ResUsage 
The ResNode macro (DBC.ResGeneralInfoView) provides the following: 
     /* Parallel efficiency of total pct of time CPUs were busy */
     (AVG(CPUBusy)*100)/NULLIFZERO(MAX(CPUBusy))
     (FORMAT 'ZZ9', TITLE 'CPU//Eff//  %'),
     /* Parallel efficiency of the logical device IOs */
     AVG(LogicalDeviceIOKB)*100 / NULLIFZERO(MAX(LogicalDeviceIOKB))
     (FORMAT 'ZZ9', TITLE 'Ldv//Eff//  %'),
