After making these settings, click the Save as Default () button on the Settings window toolbar to save the current directory settings as the default preference.

•
|
The entry in the Host file field specifies the host file used for the job. If left empty, MPD looks for a file mpd.hosts in the Linux home directory.

•
|
Select which bootstrap server MPI should use in the Bootstrap server setting.
|
•
|
The entry in the Scheduler field is the IP address of the enterprise adapter of the head node or the DNS name of the head node. The default is localhost, and it should only be changed if you submit your job from a different computer than the head node.
|
•
|
The entry in the User field is the user account that COMSOL Multiphysics uses for submitting the job. You provide the password in a separate command window that opens at execution time with the possibility to save the credentials.

Select which bootstrap server should be used by MPI using the Bootstrap server setting.

|
Specify the name of the scheduler queue in Queue name.
|
•
|
Enter the Queue name for the cluster queue.

The entry in the User field is the user account that the COMSOL Multiphysics software uses for submitting the job.

If you are connected to a COMSOL Multiphysics server on another computer, you can control the working directory used by the COMSOL Multiphysics server if you select the Specify server directory path check box and enter the path to the server Directory or Browse for the path to the mounted file system directory where the cluster job result file will be saved. This should be a fully qualified UNC path — for example, \\head1\shared. Otherwise, a temporary directory on the COMSOL Multiphysics server is used to save files. The server directory path refers to the location where the COMSOL Multiphysics server reads and writes the corresponding data (assuming a client/server configuration).

•
|
If the batch job has another path to the directory, select the Specify external COMSOL batch directory path check box and enter the path to the external process (batch) directory in the Directory field or click Browse. The cluster job uses this path from the compute node to access the input file and write back the result. On Windows this must be a fully qualified UNC path, for example, \\head1\shared\clusterprojects. The external COMSOL batch directory path refers to the location where the batch process reads and writes the data.

|
If the COMSOL software is installed in a directory other than where the COMSOL Desktop runs, select the Specify external COMSOL installation directory path check box and then specify the installation directory (click Browse or enter the path to the Directory). This can occur if you are submitting jobs to a job scheduler. Typically on Windows this is the UNC path to the COMSOL installation root directory for the compute nodes to access the required COMSOL binaries — for example, \\head1\shared\COMSOL56.
|
COMSOL Multiphysics must be installed on the remote machine and all settings must be specified correctly in the Specify external COMSOL batch directory path and Specify external COMSOL installation directory path settings according to how COMSOL Multiphysics is installed on the remote machine and the remote machines working directories.
|
You can also make changes to how some of these settings are displayed throughout COMSOL Multiphysics in The Preferences Dialog Box in the Remote Computing and Multicore and Cluster Computing sections.
