AMDGPU v2.0.0

Diff since v1.3.6

Breaking changes:

Update unsafe_wrap to match Base definition: remove lock kwargs and add own kwarg.

Changes:

  • Better kernel exception reporting mechanism:

    :::julia julia> using AMDGPU

    julia> function ker!(x) x[0] = 1 return end ker! (generic function with 1 method)

    julia> x = ROCArray(zeros(Int, 1));

    julia> @roc ker!(x);

    julia> AMDGPU.synchronize() ERROR: GPU Kernel Exception: BoundsError: Out-of-bounds array access workitemIdx: (x = 0x00000001, y = 0x00000001, z = 0x00000001) workgroupIdx: (x = 0x00000001, y = 0x00000001, z = 0x00000001) Stacktrace: [1] error(s::String) @ Base ./error.jl:35 [2] throw_if_exception(dev::HIPDevice) @ AMDGPU ~/.julia/dev/AMDGPU/src/exception_handler.jl:149 [3] synchronize(stm::HIPStream; blocking::Bool, stop_hostcalls::Bool) @ AMDGPU ~/.julia/dev/AMDGPU/src/highlevel.jl:40 [4] synchronize @ ~/.julia/dev/AMDGPU/src/highlevel.jl:36 [inlined] [5] synchronize() @ AMDGPU ~/.julia/dev/AMDGPU/src/highlevel.jl:36 [6] top-level scope @ REPL[5]:1

  • Disable eager GC by default (instead users should use GPUArrays.@cached).

  • Implement KA.pagelock!.
  • Remove old nonblocking sync (pre ROCm 6.0).
  • Docs: Add FAQ entry for AMDGPU on Archlinux.
  • Docs: Add SIMD docs & re-include installation tips.
