Juan Fumero

Lead Architect of the TornadoVM Project & Research Fellow @OfficialUoM

Juan Fumero is a Research Fellow at the University of Manchester. His research topics are Heterogeneous High-Level Languages Virtual Machines, GPGPUs, and distributed computing. Currently, he is working as part of the TornadoVM project for bringing automatic GPU and FPGA JIT compilation and execution for Java programs. He also collaborates with Intel to bring oneAPI into TornadoVM for performing code optimizations for Intel compute architectures (xPUs). Juan received a Ph.D. degree from The University of Edinburgh on Accelerating Interpreted Programming Languages on GPUs for Java, R, and Ruby. Additionally, he has also worked as an intern at Oracle Labs and CERN, implementing compilers, and evaluating parallel techniques for multi-core systems.

Level Up Your Java Performance with TornadoVM

Heterogeneous hardware such as Graphics Processing Units (GPUs) and Field Programmable Gate Arrays (FPGAs) are widely used for specific domains of applications such as Machine Learning, Data Science, Numerical Analytics and Fintech, due to the offer of a higher level of performance.

The increased performance, however, comes at the cost of programmability since different programming models and frameworks are required to program different classes of devices (GPUs, FPGAs, CPUs), thereby leading to code fragmentation. This makes the programmability of these devices more difficult to develop, and harder to understand and maintain, especially from high-level programming languages such as Java.

This talk will give an overview of the TornadoVM project, a parallel programming framework, and a Virtual Machine for transparently offloading Java programs onto GPUs and FPGAs. We will explain why and when it is beneficial to run on heterogeneous hardware. Besides, we will explain how developers can program and benefit from the GPUs and FPGAs processing power from Java using TornadoVM. Finally, we will give an overview regarding how TornadoVM compiles, optimizes and selects the best possible device for execution for different backends, totally transparent to the user.
