> TITLE: HPVM: Simplifying Heterogeneous Parallel Programming
> Prof. Vikram Adve, University of Illinois, Urbana-Champaign
> 
> ABSTRACT: 
> 
> Heterogeneous parallel systems are attractive because they use specialized
> computing elements, including GPUs, vector hardware, FPGAs, and
> domain-specific accelerators, that can greatly improve energy efficiency,
> performance, or both, compared with traditional homogeneous systems.  
> A major drawback, however, is that programming and reasoning about
> heterogeneous parallel systems is highly challenging for application
> developers, language and compiler designers, and hardware engineers.  In the
> HPVM project, we are developing a unified parallel program representation,
> Heterogeneous Parallel Virtual Machine, that aims to capture the wide range
> of parallelism available in such systems.  We use the HPVM representation
> for three different purposes: (1) a compiler intermediate representation
> (IR), (2) a virtual ISA for shipping (virtual) object code, and (3) a
> representation for runtime scheduling.  We have implemented the HPVM IR and
> associated compiler tools as an extension of the LLVM compiler
> infrastructure.  In this talk, I will describe the HPVM representation,
> experimental results demonstrating the ability of HPVM to achieve
> performance comparable to separately hand-tuned code for GPUs and vector
> hardware, and to enable highly flexible scheduling policies.  I will
> conclude with a brief discussion of how well-chosen system interfaces can
> enable highly programmable, specialized hardware, and the influence of such
> interfaces on key layers of the system stack.

> Vikram Adve is the Donald B. Gillies Professor and Interim Head of Computer
> Science at the University of Illinois at Urbana-Champaign, and has
> affiliate appointments with the Coordinated Sciences Laboratory and the
> Information Trust Institute.  Adve's research interests lie in developing
> and using compiler techniques to improve the performance, programmability
> and reliability of computer systems.  Adve and his Ph.D. student, Chris
> Lattner, co-designed the LLVM Compiler Infrastructure, which enabled novel
> compilation capabilities for a wide range of languages.  LLVM is widely
> used in industry today, ranging from mobile devices (e.g., in iOS and
> Android) to supercomputers (e.g., at Cray and NVIDIA) to data centers
> (e.g., at Google).  Adve, Lattner and Evan Cheng received the ACM Software
> System Award in 2012 for co-developing LLVM (making UIUC the only
> University to win this Award twice: the Mosaic Web Browser won it in 1995).
> Adve has won a ten-year-retrospective Most Influential Paper award at CGO
> 2004, and distinguished paper awards at several conferences including PLDI
> 2005, SOSP 2007 and ICSE 2011.  Adve's Ph.D. student, Robert Bocchino, won
> the 2010 ACM SIGPLAN Outstanding Dissertation Award and another
> Ph.D. student, John Criswell, won Honorable Mentions for both the 2014 ACM
> SIGOPS Dissertation Award and the 2014 ACM Doctoral Dissertation Award.
> Adve is a Fellow of the ACM and was named a University Scholar at the
> University of Illinois in 2015.
