Abstract

Modern computers are collections of heterogenous components, including GPUs, TPUs, NPUs, FPG As and other devices that carry out computing tasks but which are not the central CPU . We are proposing novel methods of program compilation, transformation and scheduling that take advantage of the entire system so that computation takes place in the most appropriate place at the most propitious time. Using LLVM IR , optimizers, and a performance aware scheduler, we can maximize utilization while reducing execution times for arbitrary workloads, freeing developers from treating modern computers as if they were fixed function platforms. This research has applications in high performance computing, embedded systems and security due to the centrality of run time program transformation in our system.

Bio: George V. Neville-Neil, works on networking and operating system code for fun and profit. He also teaches courses on various subjects related to programming. His areas of interest are computer security, operating systems, networking, time protocols, and the care and feeding of large code bases. He is the author of The Kollected Kode Vicious and co-author with Marshall Kirk McKusick and Robert N. M. Watson of The Design and Implementation of the FreeBSD Operating System. For nearly twenty years he has been the columnist better known as Kode Vicious. Since 2014 he has been an Industrial Visitor at the University of Cambridge where he is involved in several projects relating to computer security. He earned his bachelor’s degree in computer science at Northeastern University in Boston, Massachusetts, and is a member of ACM , the Usenix Association, and IEEE . His software not only runs on Earth but has been deployed, as part of VxWorks in NASA ’s missions to Mars. He is an avid bicyclist and traveler who currently lives in New York City. He is currently a PhD student at Yale University working with Robert Soulé, Avi Silberschatz and Peter Alvaro.
