Almost everything I have done is open-source. My current work, and hobby, is to increase, improve and mature TornadoVM, an ongoing project at the University of Manchester. See below for more details.

If you find any of these projects interesting, feel free to drop me an email.

TornadoVM: Heterogeneous Virtual Machine

October 2017 - present

A brand new Virtual Machine for Heterogeneous Computing developed at The University of Manchester. It makes use of the new Graal compiler for running Java programs on multi-core CPUs, GPUs and FPGAs via OpenCL. Compilation and execution on heterogeneous devices are transparent to the users.

TornadoVM is open-source, and it is fully available at https://github.com/beehive-lab/TornadoVM

FastR-OpenCL Compiler: R JIT compiler and runtime for GPUs

March 2016 - August 2016

Using the Marawacc compiler framework (see below), I extended the existing OpenCL JIT compiler and the Partial Evaluation (in GraalVM) to allow compiler developers automatic GPU JIT compilation and execution of the R dynamic typed language. This project was part of my PhD.

This compiler is now open-source and it is available at https://bitbucket.org/juanfumero/fastr-gpu.

Marawacc: Java JIT compiler for GPUs

January 2014 - August 2017

Marawacc is a compiler framework for executing Java applications on GPUs automatically.
It is composed of an API for parallel and heterogeneous programming (we called it JPAI), a JIT compiler that transforms, at runtime, Java bytecode intro OpenCL, and a runtime system that optimises the code and efficiently manages data transformations between Java and OpenCL. This project was part of my PhD.

This project is now open-source and it is available at https://bitbucket.org/juanfumero/marawacc

June - November 2015

FastR + Flink is a project I work on during my internship at Oracle Labs. We connected the FastR implementation (R within Truffle+Graal) and Apache Flink, allowing to execute distributed stream and batch data processing via R. This is now an open source project:

This project is open-source, and it is available at https://bitbucket.org/allr/fastr-flink

Vectorization with Haswell and CilkPlus at CERN

June-September 2013

With the release of the Intel Sandy Bridge processor, vectorization ceased to be a “nice to have” feature and became a necessity. This work is focused on optimization, running comparative measurements of available vectorization technologies currently under investigation by the CERN Concurrency Forum. In particular, the project involves an assessment of the limits of autovectorization in two compilers, an evaluation of CilkPlus as implemented in ICC/GCC and an evaluation of AVX/AVX2 benefits with respect to legacy SSE workloads.

Unfortunatelly, this project is not open-source. :-(

[Master Project] yacf (Yet Another Compiler Framework)

Source to Source compiler which parses C code with OpenMP and OpenACC directives and produce CUDA and OpenCL C kernels. This source to source also generates calls to our runtime (Frangollo), which manages memory and the execution between multiple devices.

This project is open-source and available at https://code.google.com/archive/p/yacf/
