ESE Seminar: “Hardware Acceleration in the World of Emerging Applications”
January 25, 2019 at 11:00 AM - 12:00 PM
Abstract: Semiconductor technology scaling coming to a screeching halt, coupled with the explosion of data in almost every facet of our lives, makes processing large volumes of data efficiently a critical problem to solve. In this talk, I will highlight three main challenges in designing accelerators and demonstrate that domain-specific hardware acceleration and specialization can provide orders of magnitude in compute efficiency for emerging applications. I will introduce the concept of datatype acceleration, where hardware primitives are designed to directly operate on already-defined software data structures and data containers, and show that specializing both the compute and memory subsystem provides orders of magnitude improvements in performance and energy efficiencies. Creating specialized encapsulated data accesses and datapaths allows us to mitigate unnecessary data movement, take advantage of traditional optimization techniques such as data and pipeline parallelism, and consequently provide substantial energy savings while obtaining significant performance gains. As case studies for three emerging application domains, I will briefly touch on accelerating database and graph analytics while offering in-depth examples in accelerating genomic analytics on the AWS EC2 F1 instances. As a vision for future hardware acceleration research, I will demonstrate how to create an ecosystem that makes designing, deploying, and using custom hardware almost as easy as writing and using software.
