GPU Acceleraiton of AUV Processing
There exists a need for innovative, cost-effective, parallel architectures for autonomous acoustic processing to significantly increase the processing capability for new autonomous underwater sensing systems. SOFAR Acoustics is conducting an effort to deliver a cost-effective, low-power, highly accelerated execution environment for the underwater acoustic signal processing on Autonomous Underwater Vehicles (AUVs), addressing diverse operational constraints given by space, power consumption, numerical accuracy, and access to communication infrastructure. Most GPU architectures, such as the top-performing Nvidia Kepler K-40, can deliver massive amounts of parallel computation through hundreds of arithmetic-logic unit lightweight cores, but require approximately 300 Watts to operate and are therefore not viable options for these environments. SOFAR Acoustics can provide a cost-effective COTS hardware/software processing acceleration solution capable of perform within a single-digit Watt power-budget, while at the same time providing speedup of at least five times over the current single threaded processing.
