Software Defined Networking (SDN) provides efficient network and traffic management for data center network. As underlying devices in SDN, SDN switches must maintain a large number of hardware counters. Implementation of these counters faces serious challenges for SDN switches, i.e., High memory consumption and inflexibility. Thus, we previously proposed Software Defined Hardware Counters (SDHC),...
Coarse Grained Reconfigurable Arrays (CGRAs) are typically very efficient for a single task. However all functional units are required to perform in lock step, wasting resources and making complex programming flows difficult. Massively Parallel Processor Arrays (MPPAs) excel at executing unrelated tasks simultaneously, but limit the amount of resources dedicated to a single task. We propose an architecture...
This is the first paper describing the IBM Blue Gene/Q interconnection network and message unit. The Blue Gene/Q system is the third generation in the IBM Blue Gene line of massively parallel supercomputers. The Blue Gene/Q architecture can be scaled to 20 PF/s and beyond. The network and the highly parallel message unit, which provides the functionality of a network interface, are integrated onto...
