<p>A method for scheduling transfers in a printing machine (Fig. 2) of the type having a scheduler (162;Fig. 9) communicating with both a first disk (Disk 0) and a second disk (Disk 1), the first and second disks having a combined bandwidth. The method for scheduling comprises the following steps: First, a first transfer (CurrentOp1) to be performed on a first location of the first disk (Disk 0) during a first time interval (tSX1-tDX1) and a second transfer (NextOp 1) to be performed on a second location of the first disk (Disk 0) during a second time interval (tSX2-tDX2) are both scheduled, with the scheduler (162), so that a first time gap interval (tGAPx) exists between the first time interval (tSX1-tDX1) and the second time interval (tSX2-tDX2 ). Second, a third transfer (CurrentOp2) to be performed on a first location of the second disk (Disk 1) during a third time interval (tSY1-tDY1) and a fourth transfer (NextOp2) to be performed on a second location of the second disk (Disk 1) during a fourth time interval (tSY2-tDY2) are both scheduled, with the scheduler (162), so that a second time gap interval (tGAPy) exists between the third time interval (tSY1-tDY1) and the fourth time interval (tSY2-tDY2). Finally, a fifth transfer (InsertOp) to be performed during a fifth interval (tSI-tDI) is scheduled, with the scheduler (162), so that the fifth interval (tSI-tDI) occurs during either the first time gap interval (tGAPx) or the second time gap interval (tGAPy) in a manner that maximizes the combined bandwidth of the first (Disk 0) and second (Disk 1) disk. <IMAGE></p> |
