Method Detail

startMappingScheme

public void startMappingScheme()

Description copied from class: MappingScheme

This method is invoked after the servers and the job classes are defined. It is invoked before the start of the operation. In this method, initialization operations are defined. For instance, if the mapping scheme depends on a thread, the thread is initialized and started.

Specified by:

startMappingScheme in class MappingScheme

getMin

public Server getMin(Job job)

mapJob

public void mapJob(Job job)

Description copied from class: MappingScheme

The implementation of this method determines the mapping scheme. It is invoked by the mapper object. The job is sent to the active MappingScheme concrete object (e.g. the LPAS DG object or the Gcu object). This object then makes the mapping decision according to appropriate policy.

Parameters:

job - the job object to be mapped.

stopMappingScheme

public void stopMappingScheme()

Description copied from class: MappingScheme

In this method, the program- mer should define operations that stop the execution of the system processes (e.g mapping and generation). This can be useful if the system execution is wished to be restarted after stopping it.

Specified by:

stopMappingScheme in class MappingScheme

handleJobTimeOut

public void handleJobTimeOut(long jobID)

Description copied from class: MappingScheme

The implementation of this method determines what should happen a job times out. One way of handling a time-out for instance, is to resubmit the timed-out job. This way was chosen for the implemented schemes.

Specified by:

handleJobTimeOut in class MappingScheme

serverIsDown

public void serverIsDown(int serverID)

Description copied from class: MappingScheme

The implementation of this method determines what should happen a server goes down. For instance, the LPAS_DG policy resolves the LP allocation.

Specified by:

serverIsDown in class MappingScheme

Parameters:

serverID - the serverID of the server that became unavailable

serverIsUp

public void serverIsUp(int serverID)

Description copied from class: MappingScheme

The implementation of this method determines what should happen a server becomes up. For instance, the LPAS_DG policy resolves the LP allocation.

Specified by:

serverIsUp in class MappingScheme

Parameters:

serverID - the serverID of the server that became unavailable
