To set up parallel processing for planning

To 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 setup. For general information on the concept, refer to Parallel processing concept.

To set up parallel processing, perform the following steps:

  1. Start the Performance Parameters (cpcom0100m000) session.

  2. Select an appropriate value for the Workload per Server field.

    For more information, refer to Workload per server.

  3. Select or clear the Workload Based on Operations check box, as appropriate.

    For more information, refer to Workload based on operations.

  4. Select or clear the Dynamic Workload Calculation check box, as appropriate.

    For more information, refer to Dynamic workload calculation.

  5. Select the Parallel Processing check box for the sessions you want to run on multiple bshells.

    The first time that you select the Parallel Processing check box for a session, that session appears in the Parallel Processing Configuration (ttaad7520m000) session.

  6. Start the Parallel Processing Configuration (ttaad7520m000) session, and double-click the session that must run on multiple bshells.
  7. In the Servers field, specify the number of bshells, that is, the number of parallel processes, available for that session.
  8. In the Mode field, select the appropriate value.
Note

Each time you start a planning run, you can select the Parallel Processing check box in the planning sessions. However, you must only set the number of servers in the Parallel Processing Configuration (ttaad7520m000) session once.
