Apache Spark Accelerated Deep Learning Inference for Large Scale Satellite Image Analytics

no code implementations8 Aug 2019 Dalton Lunga, Jonathan Gerrand, Hsiuhan Lexie Yang, Christopher Layton, Robert Stewart

By taking advantage of Apache Spark, Nvidia DGX1, and DGX2 computing platforms, we demonstrate unprecedented compute speed-ups for deep learning inference on pixel labeling workloads; processing 21, 028~Terrabytes of imagery data and delivering an output maps at area rate of 5. 245sq. km/sec, amounting to 453, 168 sq. km/day - reducing a 28 day workload to 21~hours.
