Automation, Compilers, and Code-Generation

    The topic for this semester is Automatic Code Generation.

    The objective of this semester's seminar is to look closely into the process behind code generation, both in general purpose compilers and domain specific languages.
    In regard to general purpose compilers (gcc, llvm, openCL, Cilk), we want to investigate their ability to automatically use vector instructions.
    With respect to domain specific languages, we are interested in studying the techniques that are used in practice. A (non final and non exhaustive) list of test cases follows. Tensor Contraction Engine (TCE); the FFTW and Spiral projects for digital signal processing; BTO, Eigen, DxT and CLAK for linear algebra; the Fenics project for PDEs.
