32.2.1 Setting Parallel Scheduler Options in FLUENT Launcher

Activating the Use Microsoft Job Scheduler (Windows) or the Use Job Scheduler (Linux/UNIX) option under Options in FLUENT Launcher enables the Scheduler tab (visible when you select the Show More >> button). The Scheduler tab allows you to specify settings for running ANSYS FLUENT with various job schedulers (e.g., the Microsoft Job Scheduler for Windows, or LSF and SGE on Linux/UNIX).

Figure 32.2.2: The Scheduler Tab of FLUENT Launcher (Windows Version)

For the Windows 32-bit HP-MPI, Windows 64-bit CCP and HP-MPI, you can specify that you want to use the Microsoft Job Scheduler by selecting the Use Microsoft Job Scheduler check box under Options in FLUENT Launcher. Once selected, you can then enter a machine name in the Compute Cluster Head Node Name text field in the Scheduler tab. If you are running ANSYS FLUENT on the head node, then you can keep the field empty. This option translates into the proper parallel command line syntax for using the Microsoft Job Scheduler (see Section  32.3.1).

If you want ANSYS FLUENT to start after the necessary resources have been allocated by the Scheduler, then select the Start Until Resources Available checkbox.

To create the job submission XML file at the time when you launch ANSYS FLUENT, select the Create Job Submission XML option (available once you specify a journal file in the General Options tab) and enter the name of the XML file in the corresponding text field, or click to browse for an appropriate XML file. The XML file can be used to submit jobs to ANSYS FLUENT without having to use FLUENT Launcher.

For Linux/UNIX, select the Use Job Scheduler check box under Options to use one of two available job schedulers in the Scheduler tab.

• Select the Use LSF radio button to use the LSF load management system with or without checkpointing. If you select Use Checkpointing, then you can specify a checkpointing directory in the Checkpointing Directory field. By default, the current working directory is used. In addition, you can specify a numerical value for the frequency of automatic checkpointing in the Automatic Checkpoint with Setting of Period field.

  For more information, see the separate ANSYS FLUENT load management manual, Running FLUENT Under LSF available on the User Services Center.

• Select the Use SGE radio button to use the SGE load management system. You can choose to set values for the SGE qmaster, as well as the SGE queue, or the SGE pe. Alternatively, you can select Use SGE settings check box and specify the location and name of the SGE configuration file.

  For more information, see the separate ANSYS FLUENT load management manual, Running FLUENT Under SGE available on the User Services Center.

For Windows, you also have the ability to run in batch mode (using the Run in Batch Mode check box) when you provide a journal file (designated in the General Options tab) which exits ANSYS FLUENT at the end of the run.
