Run => Override Cluster Options
When you run an em analysis job on your LSF cluster, the operation of emCluster is controlled by entries made by you in the emCluster initialization file, emcluster.ini, during the installation and setup of emCluster. You may wish to override these settings for a particular analysis job. Selecting Run => Override Cluster Options from the main menu of an analysis monitor batch window opens the Override Cluster Options dialog box which allows you to change some of the controlling parameters of LSF Cluster. When the dialog box is opened, the values in your initialization file appear in the dialog box. Changes made in this dialog box apply only to jobs run in this particular batch window. See below for details.
Note: The LSF Cluster option is only available with the Sonnet Professional Suite and must be purchased separately. Please check with your system administrator if you are not sure of the availability of this program.
Host List
Enter the host servers on your LSF cluster which you wish to use for processing jobs submitted from this batch window. This allows you to select specific hosts on which to run your job. You may click on the Configure button to open the LSF Cluster Host List Selection dialog box which allows you to select the desired host(s). You may also directly edit the contents of the text entry box. If there are no entries, then all available host servers in the cluster may be used.
If specify a queue for your LSF job, any computer which appears in your HostList MUST also be included in the queue. If you have a computer in your host list upon which your queue may not run, LSF issues an error message and does not process the job.
Queue
Enter the LSF queue which you wish to use for processing jobs submitted from this batch window. This allows you to select specific queue(s) on which to run your job. These queues should be previously defined for your LSF cluster. If no queue is entered, then the default LSF queue, normal, is used.
Frequency Splitting
This section of the dialog box allows you to control how many jobs your analysis is split into. You may not use frequency splitting with an optimization or parameter sweep.
No splitting: The job is submitted as one analysis job to the cluster and one host server analyzes your circuit at all the specified analysis frequencies. When this option is selected, then response data and status information, such as you would see with a local analysis, is sent to the analysis monitor. This is defined as running interactively. This is the only setting you may use if your analysis includes an optimization or parameter sweep.
Split into no more than < n> jobs: This selection limits the number of jobs your analysis may be split into. The project is duplicated the number of times you enter in the adjacent text entry box and each duplicate project analyzes the circuit for a subset of the requested analysis frequencies. For example, if your analysis is for the frequencies 2, 4, 6, 8, 10, 12, 14, and 16 GHz and you have entered 4 as the maximum number of jobs then the first job analyzes at 2 and 4 GHz, the second project at 6 and 8 GHz and so on.
Split into one job per frequency: The job is split into one job per requested analysis frequency. If more jobs are created than there are host servers in your cluster, then multiple jobs will be submitted to some host servers. If you have a sufficient number of host servers in your cluster, this option results in the greatest efficiency for your processing.
Poll Interval
Enter the amount of time, in seconds, between updates from emcluster on the progress of the analysis. The value should be an integer between the values of 5 and 300.
Set to Default
Clicking on this button will set all the values in the dialog box to the values contained in the emCluster initialization file.
