The set of default load parameters might not be adequate to completely describe the load situation in a cluster. This possibility is especially likely with respect to site-specific policies, applications, and configurations. Therefore grid engine software provides the means to extend the set of load parameters. For this purpose, sge_execd offers an interface to feed load parameters and the current load values into sge_execd. Afterwards, these parameters are treated like the default load parameters. As for the default load parameters, corresponding attributes must be defined in the complex for the site-specific load parameters to become effective. See Default Load Parameters for more information.
