Parallel processing conceptTo improve processing speed, some planning runs can run in parallel on multiple processors (CPUs). To do this, set these sessions to run in multiple bshells. Each bshell can run on its own CPU. This section describes the general concept. For information on the setup, refer to To set up parallel processing for planning. Application of the parallel processing concept The sessions for which parallel processing is available include these planning sessions:
Note The process that transfers planned orders to the execution level can only use one bshell. Distribution of items across bshells The order planning process takes the plan item's phase number into account. The planning of plan items with phase number 1 cannot start until all plan items with phase number 0 have been planned; otherwise, some dependent demand might be missing for the second level. If you use multiple bshells, LN completes the following steps:
