Algorithm 1
Proactive thermal VM scheduling.
| IF (Event(Application_Arrival) ==TRUE) | | Put new request in waiting queue | | FOREACH physical machine in the Unified list | | If (current temperature < threshold temperature) | | Estimate for each node and put in the predict queue | | END IF | | END FOREACH | | Sort predict Queue in the decreasing order of | | FOREACH VM request in waiting queue | | Check availability of VM in the first node in predict queue | | IF Available then allocate VM to this VMRequest | | Update Unified and Local lists. | | ELSE | | Check next node in the Predict Queue till last node is reached | | END ELSEIF | | IF no node is available | | Event(Activate_SM) and allocate VMRequest to a new VM on this SM. | | ENDIF | | END FOREACH | | ENDIF | | IF (Event(Application_Complete) ==TRUE) | | Event(Free_VM) | | Update Unified and local lists | | IF(Active_VM_Count == 0) | | Event(Hibernate(SM)). | | Update Unified and Local lists. | | ENDIF | | ENDIF |
