Summit 2016 Deploying Accelerators At Datacenter Scale Using Spark

June 6, 2016 05:00 PM PT

Accelerators, such as GPUs and FPGAs, have been gaining popularity in commodity clusters due to their high computing and energy efficiency. However, deploying accelerators at a large scale still requires significant effort when using existing approaches. In this talk, we present Blaze, an accelerator-aware runtime system that enables rapid warehouse-scale accelerator deployment for the Hadoop/Spark ecosystem. In particular, Blaze provides accelerator management for data-intensive scalable computing (DISC) systems in a cluster with heterogeneous accelerator platforms, including GPUs and FPGAs. Blaze also provides APIs for system architects to design cluster-wide ready-to-use accelerators, and APIs for DISC system developers to use accelerators. Blaze demonstrates improved DISC system throughput and accelerator utilization on a cluster with commodity FPGA and GPU cards.
