Configuring resources

Cluster resources get distributed throughout the namespace according to share entitlements (share ratio) as set in the resource plan. The cluster administrator may set the share ratio in the resource plan. The share ratio assigned to a consumer node is the ratio of the resource available to the parent, that a child gets. For example, if there are 2 children, and each has a share ratio of 1, then each child gets 50% of the parents GPUs. If the parent has 100 GPUs available to distribute, then each child gets 50 GPUs.

A best practice to help you better leverage the distribution of resources available for sharing is to interpret the share ratio as a minimum share value. These minimum values are complemented by the maximum share values, or quota limits. A distribution policy that includes resources available for sharing must always yield actual share values between the minimum and maximum constraints. So long as this remains the primary expectation, the complexities of the actual distribution algorithm do not matter.
