| # To set up multiple bshells 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 of multiple bshells. For general information on the concept of multiple bshells, refer to Multiple bshells concept. To set up multiple bshells, perform the following steps: Start the Performance Parameters (cpcom0100m000) session. Select an appropriate value for the Workload per Server field. For more information, refer to Workload per server. Select or clear the Workload Based on Operations check box, as appropriate. For more information, refer to Workload based on operations. Select or clear the Dynamic Workload Calculation check box, as appropriate. For more information, refer to Dynamic workload calculation. Select the relevant check box for the sessions you want to run on multiple bshells. The following list shows the relevant sessions and check boxes: The Parallel Processing check box in the Generate Order Planning (cprrp1210m000) session. The Parallel Processing check box in the Initialize, Roll, and Update Scenario (cprpd4200m000) session. The Parallel Processing check box in the Generate Pegging Relations (cprrp0240m000) session. The Parallel Processing check box in the Generate Planned Supply based on Forecast (cpvmi1211m000) session. The first time that you select the Parallel Processing check box for a session, that session appears in the Performance Boosters (tcmcs0597m000) session. Start the Performance Boosters (tcmcs0597m000) session, and double-click the session that must run on multiple bshells. The details session opens. For performance booster Number of Servers, set the Value field to the number of bshells, that is, the number of parallel processes, available for that session. 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 Performance Boosters (tcmcs0597m000) session once.
