Title: General-Purpose Processing on AI/ML Accelerators
Abstract:
The significance of artificial intelligence (AI) and machine learning (ML) applications has
changed the landscape of computer systems: AI accelerators start to emerge in a wide
range of devices, from mobile phones to data servers. In addition to the direct
contribution of performance gain in AI/ML workloads, the introduction of AI/ML
accelerators brings a new flavor of computation model that any matrix-based algorithms
can leverage. However, the highly application-specific designs of these accelerators
place hurdles for a wider spectrum of workloads
In this talk, Hung-Wei will discuss state-of-the-art AI/ML accelerators and share his
experience in transforming existing algorithms into AI/ML-specific functions. Hung-
Wei’s research group has demonstrated up to 288x speedup for database join operations
by using NVIDIA’s tensor cores. If we can extend the design of AI/ML accelerators to
support various matrix operations, a set of matrix applications can achieve more than
10x speedup over conventional GPUs. Finally, Hung-Wei will talk about the new
programming model, paradigms that new hardware accelerators enable, simultaneous
and heterogeneous multithreading (SHMT). By using GPUs and TPUs at the same time,
SHMT reveals 2x speedup over state-of-the-art GPU implementations. Hung-Wei will
also discuss some extensions that are essential to make the upcoming revolutions of
general-purpose computing successful.
