Abstract
Methods, apparatus, and product for tracking network contention on links among compute nodes of an operational group in a point-to-point data communications network of a parallel computer are disclosed. In embodiments of the present invention, each compute node is connected to an adjacent compute node in the point-to-point data communications network through a link. Tracking network contention according to embodiments of the present invention includes maintaining, by a network contention module on each compute node in the operational group, a local contention counter for each compute node, each local contention counter representing network contention on links among the compute nodes originating from the compute node; and maintaining a global contention counter, the global contention counter representing network contention currently on all links among the compute nodes in the operational group.
