[llvm-dev] RFC: An Extension Mechanism for Parallel Compilers Based on LLVM

[Adve, Vikram Sadanand via llvm-dev]

This is not focused on OpenMP-type systems – we aim to support a wide range of languages.  Tapir supports Cilk, for example.  HPVM is flexible enough to support both general-purpose languages like OpenMP, OpenCL and CUDA, as well as domain-specific ones like TensorFlow.

Halide and Tiramisu are more domain-specific, and could in principle be hosted on top of this mechanism (although there may not be any reason to).

The point about “vastly more targets” seems like a misunderstanding: the RFC puts no restrictions on how many targets any parallel compiler hosted on top of the mechanism could target (e.g., HPVM can target as many as Halide or Tiramisu).

    This appears this is an incremental extension mechanism for openMP-type
    systems.   
    
    I was wondering if the authors are familiar with halide (halide-lang.org)
    or the recent Tiramisu paper (https://arxiv.org/pdf/1804.10694.pdf).
    
    
    These compilers can target a vastly wider range of hardware architectures
    one of which could be openMP and get amazing performance results.
    
    
    While I think it is most likely out of scope for current work it may be
    helpful to keep these more specialized compilers in mind.
