Abstract
A computer chip, a method, and computer program product for managing reservation between processing nodes with token constraints. The computer chip includes a plurality of processing nodes interconnected in an on-chip data transfer network configured in a circular topology. The processing nodes include a reservation mechanism that manages reservations made by the processing nodes. The reservation mechanism applies a reservation policy when a starvation condition is met on a processing node. The reservation policy separates the processing nodes into partition groups and dictates that a processing node may only send a reservation when their assigned partition group is active. Each of the processing nodes includes a buffer for storing messages that is divided into a pool of tokens and a pool of reservation tokens. The tokens are used for standard message transmission and the reservation tokens are reserved for token reservation requests received at a destination node.
