Class SimTask

java.lang.Object
  lbg.simulator.SimTask

All Implemented Interfaces:

GridApplication

public class SimTask
extends java.lang.Object
implements GridApplication

A SimTask is a wrapper class enabling the LBG Simulator to be run as a GridApplication.

Particularly useful to run a parameter sweep over multiple scenarios.

Method Detail

setInputData

public void setInputData(GridData[] datas)
                  throws GridException

Sets the Grid application's input data files.

Specified by:

setInputData in interface GridApplication

Parameters:

datas - target simulation description file

Throws:

GridException - If the data is not what it should be.

setParameters

public void setParameters(java.lang.Object[] parameters)
                   throws GridException

Description copied from interface: GridApplication

Sets the Grid application's input parameters.

Specified by:

setParameters in interface GridApplication

Parameters:

parameters - An array of parameters as Objects. Can be empty, but never null.

Throws:

GridException - If the parameters are not what they should be.

setSupplier

public void setSupplier(java.lang.String supplier_id)
                 throws GridException

Description copied from interface: GridApplication

Sets the id of the Supplier Peer that controls the Resource running the Grid application

Specified by:

setSupplier in interface GridApplication

Parameters:

supplier_id - Supplier Peer id

Throws:

GridException - If the Supplier Peer id is not what it should be.

setPlaypen

public void setPlaypen(java.lang.String playpen_dir)
                throws GridException

Description copied from interface: GridApplication

Sets the playpen directory of the Resource where the Grid application can write and read temporary files.

Specified by:

setPlaypen in interface GridApplication

Parameters:

playpen_dir - playpen directory

Throws:

GridException - If the playpen directory is not what it should be.

compute

public void compute()

Description copied from interface: GridApplication

Runs the Grid application. As this method cannot throw any exception, one should print his stack traces to stderr in case of error. They will be returned in the logs if the application completes (i.e. doesn't fail elsewhere).

Specified by:

compute in interface GridApplication

getResult

public byte[] getResult()

Description copied from interface: GridApplication

Gets computed results.

Note: if no results are produced, new byte[0] can be used as a legal value.

Specified by:

getResult in interface GridApplication

Returns:

computed results, or null if a transient error happened
