An EGO cluster administrator must define how ncpus is computed. Usually, the number of available EGO slots is equal to the value of ncpus; however, slots can be redefined at the resource group level. The ncpus definition is globally applied across the cluster.
It is not necessary to configure EGO_DEFINE_NCPUS in the ego.conf file as a basis for computing the number of slots per host. Symphony offers a more flexible way to define the number of host slots based on individual host attributes. Refer to Defining the number of slots per host
