Every device in AIX has interrupt level. It denotes the way in which the request from the device are submitted to the CPU for execution of task.
Interrupt : It stops the current execution of the processor and executes the interrupted process.
Steps to do binding:
# lsattr -EHl ent0 : Command to view the interrupt level of a device.
# bindprocessor -q : Command to view the processors available in the box.
# lsattr -EHl proc* : Ensure the processors have SMT on. (Simultaneous Multi-threading).
# bindintcpu <interrupt level> <processor no> : Command to bind a interrupt to a specific processor.
# vmstat -i : Command to view the bind interrupt execution.
