| X-Stack Project | Name of the DSL | URL | Target domain | Miniapps supported | Front-end technology used | Internal representation used | Key Optimizations performed | Code generation technology used | Processors computing models targeted | Current status | Summary of the best results |
|---|---|---|---|---|---|---|---|---|---|---|---|
| D-TEC | Halide | http://halide-lang.org | Image processing algorithms | Cloverleaf, miniGMG, boxlib | Uses C++ | Custom IR | Stencil optimizations (fusion, blocking, parallelization, vectorization) Schedules can produce all levels of locality, parallelism and redundant computation. OpenTuner for automatic schedule generation. | LLVM | X86 multicores, Arm and GPU | Working system. Used by Google and Adobe. | Local laplacian filter: Adobe top engineer took 3 months and 1500 loc to get 10x over original. Halide in 1-day, 60 lines 20x faster. In addition 90x faster GPU code in the same day (Adobe did not even try GPUs). Also, all the pictures taken by google glass is processed using a Halide pipeline. |
| DTEC | Shared Memory DSL | http://rosecompiler.org | MPI HPC applications on many core nodes | Internal LLNL App | Uses C (maybe C++ and Fortran in future) | ROSE IR | Shared memory optimization for MPI processes on many core architectures permits sharing large data structures between processes to reduce memory requirements per core. | ROSE + any vendor compiler | Many core architectures with local shared memory | Implementation released (4/28/2014) | Being evaluated for use |
| D-TEC | Heterogeneous OpenMP | http://rosecompiler.org/ | HPC applications running on NVIDIA GPUs | boxlib, internal kernels | Uses C and C++ | ROSE IR (AST) | loop collapse to expose more parallelism, Hardware-aware thread/block configuration, data reuse to reduce data transfer, round-robin loop scheduling to reduce memory footprint | ROSE source-to-source + NVIDIA CUDA compiler | NVIDIA GPUs | Implementation released with ROSE (4/29/2014) | Matches or outperforms caparable compilers targeting GPUs. |
