Systems and methods for energy proportional multiprocessor networks

A non-transitory computer-readable medium having instructions stored thereon, the instructions, when executed by one or more processors, cause the one or more processors to perform a method of providing energy proportional communication in a multiprocessor architecture, the method comprising the steps of:

• predicting a maximum amount of traffic intensity for one or more links of the multiprocessor architecture by determining channel utilization for each link of the one or more links over a predetermined time period;
• removing reactivating output ports from a set of legal adaptive routes based on the determined channel utilization;
• draining output buffers of the output ports before reconfiguration;
• and
• adjusting a throughput speed for a given link of the multiprocessor architecture based on the predicted maximum amount of traffic intensity so as to meet a minimum energy usage.

A system of providing energy proportional communication in a multiprocessor architecture, comprising:

• a memory;
• and
• one or more processors coupled to the memory, the one or more processors being configured to:
• predict a maximum amount of traffic intensity for one or more links of the multiprocessor architecture by determining channel utilization for each link of the one or more links over a predetermined time period;
• remove reactivating output ports from a set of legal adaptive routes based on the determined channel utilization;
• drain output buffers of the output ports before reconfiguration;
• and
• adjust a throughput speed for a given link of the multiprocessor architecture based on the predicted maximum amount of traffic intensity so as to meet a minimum energy usage.
