Perhaps it is too verbose but I wanted to mention the few areas users should know have changed, if they happen to try HSA out. I can certainly cut it down a bit. Any comments welcome.

Heterogeneous Systems Architecture

  • GCC can now generate HSAIL for simple OpenMP device constructs + if configured with --enable-offload-targets=hsa. A new + libgomp plugin then run these HSAIL kernels implementing these + constructs on HSA capable GPUs via standard HSA run-time.

    + +

    If the HSA compilation back-end determines it cannot output HSAIL + for a particular input, it gives a warning by default. These + warnings can be suppressed with -Wno-hsa. To give a + few examples, the HSA back-end does not implement compilation of + code using function pointers and variable-sized variables and + parameters, functions with variadic arguments as well as a number of + other less common programming constructs.

    + +

    When compilation for HSA is enabled, the compiler attempts to + compile composite OpenMP constructs + 

    +#pragma omp target teams distribute parallel for
    + into parallel HSA GPU kernels.
