The Node Manager profile is an abstraction for the amount of resources a Node Manager advertises to the Resource Manager. These profiles are set in the Myriad configuration file, myriad-config-default.yml
. Each profile is identified by zero, small, medium, and large with default CPU and memory parameters. The cluster can be configured to start with a an initial number of Node Managers. By default, Myriad requires at least 1 NM NodeManager instance with a medium profile. See See Scaling Resources Dynamically and the Myriad Cluster API for for information about flexing up or down an scaling instance resources.

During initial startup, Myriad launches one NodeManager instance with a profile of medium through the parameter, "nmInstances": { "medium": 1 }, |
