Constructor Detail

DataGridlet

public DataGridlet(int gridletID,
                   double gridletLength,
                   long gridletFileSize,
                   long gridletOutputSize,
                   LinkedList list)

Creates a new DataGridlet object. The gridlet length, input and output file sizes should be greater than or equal to 1. By default, this constructor records the history of this object.

Parameters:

gridletID - the unique ID of this Gridlet

gridletLength - the length or size (in MI) of this Gridlet to be executed in a GridResource

gridletFileSize - the file size (in byte) of this Gridlet BEFORE submitting to a GridResource

gridletOutputSize - the file size (in byte) of this Gridlet AFTER finish executing by a GridResource

list - a list of required filenames to execute this Gridlet

DataGridlet

                   boolean record,
                   LinkedList list)

Creates a new DataGridlet object. The gridlet length, input and output file sizes should be greater than or equal to 1.

Parameters:

gridletID - the unique ID of this Gridlet

gridletLength - the length or size (in MI) of this Gridlet to be executed in a GridResource

gridletFileSize - the file size (in byte) of this Gridlet BEFORE submitting to a GridResource
