Deploying Accelerators At Datacenter Scale Using Spark

Download Slides

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.
