runD 1.0.1 Alpha

This alpha restructures repeated Compute execution around a compact,
tile-local nested plan. It removes the intermediate repeated-descriptor memory
layer and keeps execution, replay, and installed-SDK behavior tied to one
canonical plan identity.

Highlights

  • Added tile_repeat<N> for bounded nested repetition without materializing a
    descriptor per repeated invocation.
  • Reworked nested-plan lowering and execution so plan memory is proportional
    to the tile structure rather than the expanded repeat count.
  • Added checked count, offset, and identity arithmetic with deterministic
    overflow and capacity failure behavior.
  • Kept CPU, Metal, and Vulkan on the same public nested-plan contract, with
    backend-specific verification and parity coverage.
  • Updated the installed SDK, exact-version CMake consumers, performance
    measurement routes, and API/ABI documentation for version 1.0.1.

Darwin ARM64 SDK

The three attached files form one release:

  • rund-sdk-1.0.1-darwin-arm64.tar.gz
  • rund-sdk-1.0.1-darwin-arm64.sha256
  • rund-verify

Keep them together and verify the sealed producer and host tuple before use:

chmod +x ./rund-verify
sh ./rund-verify \
  ./rund-sdk-1.0.1-darwin-arm64.tar.gz \
  ./rund-sdk-1.0.1-darwin-arm64.sha256 \
  "$PWD"

The archive SHA-256 is:

ed7b59b2a92fce04982306ce84bf979c0558f6284b71b4d7db69cdc718aadc32

Verification

  • Clean Release build: 1,947 / 1,947 targets.
  • Release and installed-SDK contracts: 25 / 25 passed.
  • Exact extracted archive, 337-header closure, package identity, documentation
    examples, CPU, Metal, and Vulkan consumer routes passed.
  • Source commit: 389c036c702458668d0e1b89e06477f1b1d6c3aa.

Alpha scope

  • Darwin ARM64 is the supported binary SDK tuple.
  • The Linux x64 source-candidate workflow for this tag stopped during the
    build because GCC 13 promoted an aggressive-loop-optimization diagnostic in
    pre-existing arena.cpp code to an error. No Linux artifact is attached;
    see workflow run 30624371425.
  • Windows x64 is not supported.
  • Exact package identity 1.0.1 is intentionally not ABI-compatible with
    1.0.0 because the alpha public by-value plan representation changed.
  • The Metal warm path still walks frozen descriptors on the host; eliminating
    that remaining host loop stays open in issue #1.
