public PEList()

Method Detail

getMIPSRating

public int getMIPSRating(int id)

Gets MIPS Rating for a specified PE ID

Parameters:

id - the PE ID

Returns:

the MIPS rating if exists, otherwise returns -1

Pre Condition:

id >= 0

Post Condition:

$none

getFreePEID

public int getFreePEID()

Gets a PE ID which is FREE

Returns:

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

Pre Condition:

$none

Post Condition:

$none

getNumFreePE

public int getNumFreePE()

Gets the number of FREE or non-busy PE.

Returns:

number of PE

Pre Condition:

$none

Post Condition:

$result >= 0

setStatusPE

public boolean setStatusPE(boolean status,
                           int peID)

Sets the PE status

Parameters:

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

peID - PE id

Returns:

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

Pre Condition:

peID >= 0

Post Condition:

$none

getNumBusyPE

public int getNumBusyPE()

Gets the number of BUSY PE

Returns:

number of PE

Pre Condition:

$none

Post Condition:

$result >= 0

getByteSize

public int getByteSize()

Gets the byte size of PEList internal data members

Returns:

the byte size

Pre Condition:

$none

Post Condition:

$result >= 0

setStatusFailed

public void setStatusFailed(String resName,
                            int machineID,
                            boolean fail)

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

machineID - the id of this machine

fail - the new value for the "failed" parameter

setStatusFailed

public void setStatusFailed(boolean fail)

Sets the status of PEs of this machine to FAILED.

Parameters:

fail - the new value for the "failed" parameter
