Parameters:

peList - the pe list

Returns:

the total MIPS Rating

getMaxUtilization

public static <T extends Pe> double getMaxUtilization(List<Pe> peList)

Gets the max utilization among by all PEs.

Parameters:

peList - the pe list

Returns:

the utilization

getMaxUtilizationAmongVmsPes

public static <T extends Pe> double getMaxUtilizationAmongVmsPes(List<Pe> peList,
                                                 Vm vm)

Gets the max utilization among by all PEs allocated to the VM.

Parameters:

vm - the vm

the utilization

getFreePe

public static <T extends Pe> Pe getFreePe(List<Pe> peList)

Gets a Pe ID which is FREE.

Parameters:

peList - the pe list

Returns:

a Pe ID if it is FREE, otherwise returns -1

getNumberOfFreePes

public static <T extends Pe> int getNumberOfFreePes(List<Pe> peList)

Gets the number of FREE or non-busy Pe.

Parameters:

peList - the pe list

Returns:

number of Pe

setPeStatus

public static <T extends Pe> boolean setPeStatus(List<Pe> peList,
                                 int id,
                                 int status)

Sets the Pe status.

Parameters:

status - Pe status, either Pe.FREE or Pe.BUSY

id - the id

peList - the pe list

Returns:

true if the Pe status has been changed, false otherwise (Pe id might not be exist)

getNumberOfBusyPes

public static <T extends Pe> int getNumberOfBusyPes(List<Pe> peList)

                                  boolean failed)

Sets the status of PEs of this machine to FAILED. NOTE: resName and machineID are used for debugging purposes, which is ON by default. Use #setStatusFailed(boolean) if you do not want this information.

Parameters:

resName - the name of the resource

hostId - the id of this machine

failed - the new value for the "failed" parameter

setStatusFailed
