To set the number of workers in your cluster profile that uses a third-party scheduler such as Slurm, please use these commands below. These commands can be used without a GUI, or just with a command-line interface.

c=parcluster('MyClusterProfileName');
c.NumWorkers = 10;
c.saveProfile;

Make sure you replace "MyClusterProfileName" with your cluster profile's name, or remove this section if the cluster profile in question is your default profile. You may change the number 10 to value of your choice.

Please make sure you are using the latest version of the integrations scripts found from the link below.
