    Projects  Projects Overview  |

    This is the fourth big compiler project I have led. In the past my research groups have worked on (i) optimizing/parallelizing C (McCAT), (ii) optimizing and analyzing Java (Soot); and a compiler toolkit for language extensions and optimizations for AspectJ (abc).

    Building on those previous experiences, McLab is an exciting new project where our goal is to bring together what we have learned about static optimizations, virtual machines, and extensible compiler frameworks to the domain of dynamic scientific languages. Our intent is to work with scientists to develop languages that provide good programming models and good execution performance.

    Projects  Mc2Mc  |

    I am a PhD student supervised by Professor Laurie Hendren. My research interests are in the field of compilers, program analysis and databases. I particularly like to explore array programming languages and combine array languages and in-memory databases. I learned my first array programming language APL, when I was a third year undergraduate. Later I wrote an APL dialect ELI. The experience on ELI motivated me to continue research in programming languages.

    Projects  Pando  | Ostrich Benchmark Suite  |

    I am a PhD student in Computer Science, with a background in Computer Engineering. I am deeply interested in the leverage programming languages can provide to design complex human-computer systems to make us collectively more effective at solving the major problems of our era. My project aims at understanding the performance characteristics of modern virtual machines for high-level dynamic languages, such as JavaScript, first to design optimizations for efficiently compiling scientific languages to them, and then inform the evolution of their implementation for a better cooperation across layers.

    Guang Hu

    guangh@cs.mcgill.ca

    I’m a Postdoc in computer science at McGill University’s Sable research group. I received the Postdoctoral Fellowship Scholarship for his postdoctoral research at McGill from the Fonds de recherche du Québec - Nature et technologies (FRQNT) of the government of Quebec, Canada in 2013. My current project is to develop the compiler tools that can automatically compile Matlab code and generate equivalent optimized Java code and Android bytecode, so that the code can also be executed on the fast developing platforms for Java and Android. Thus, scientific programmers can make better use of these platforms to make their applications more open, more efficient and more compatible with various computing environment.

    Projects  McVM & McJIT  |

    Dynamic languages such as MATLAB pose significant performance challenges, but also present great opportunities for optimizations. The dynamic behavior of programs written in those languages may be exploited to guide optimizations that improve performance. I worked under the supervision of Professor Laurie Hendren in the area of virtual machines and dynamic compilation of MATLAB-like languages. In particular, I worked on techniques and tools for optimizing dynamic languages and building on work from the virtual machine and static compiler areas.

    Vineet Kumar
    Projects  MiX10  |

    My fascination with compilers started while writing a C decompiler for my undergrad project and after three years in industry I came to McGill for the master’s programme in Computer Science. Here I joined the Sable research group under the supervision of Professor Laurie Hendren to develop MiX10, a MATLAB to X10 compiler. MATLAB is an easy to use scientific program language and is widely used by scientists and engineers. On the other hand, X10 is an object-oriented, statically typed language specifically designed for high performance computing. The aim of MiX10 compiler is to help MATLAB users take advantage of the power of high performance computing, while still writing their programs in MATLAB.

    Projects  McFlat  |

    I am working on Analysis and Transformation engine of McLab project under the supervision of Laurie Hendren. Analysis and Transformation engine computes dependence between loop statements and apply various loop transformations that could improve the performance of programs. In MatLab the loop bounds are mostly determined at run time,so the profiler component of analysis and transformation engine generates data for different runs of the program.The data is then passed to heuristic engine to estimate appropriate ranges for loops in the program. Dependence Analysis and transformations are applied on the estimated ranges. The focus of my thesis is to avoid expensive run time dependence analysis tests and do most of the computations at compile time.

    Projects  AspectMatlab  |

    I have developed the AspectMatlab as part of my masters thesis under the supervision of professor Laurie Hendren. AspectMatlab extends the base Natlab (Neat Matlab) language by introducing the aspect-oriented features. Besides the basic functions related patterns, AspectMatlab provides the array accesses and loops specific patterns, much to the needs of a scientific programmer. Currently, a beta version of AspectMatlab Compiler (amc) is available.

    Projects  McCli  |

    I have a deeply ingrained passion for programming, be it under the hat of the software engineer or of the computer scientist.I enjoy anything that poses an challenge, but have had the most fun with compilers, game development, GPU programming, security, networked systems and object-oriented design. McCli is a back-end component of the McLAB compiler targeting the .NET platform. It transforms code from a subset of the MATLAB language into statically typed .NET bytecode. It provides a path for integrating MATLAB scripts into existing .NET applications on Windows, MacOS X, Linux and even Windows Phone.

    Projects  Tamer+  |

    For the convenience of analyzing Matlab code and collecting information for later phase, tamer convert Matlab to a low level IR, tamerIR, almost three address code. This low level IR has many temporary variables and not very friendly human readable, so my project goal is trying to aggregate those simplified code back to a higher level IR and make them more human readable
