research/determinism-cost.md §4.6, in the same record and by the same procedure: the 192 payloads decoded again on every platform with every kernel set it runs (15 new runs, 0 decodes differing from the record's), and the record's time and energy runs repeated in one session per host beside the record's own build and the float decoder. On x86_64 host A the integer decode on the narrow kernels took 144.8 ms and 12.43 J of marginal package energy at quality 6 against 210.7 ms and 14.03 J for the float decode beside it (the record's build: 728.0 ms, 92.14 J). On the build host its own CPU energy fell from 11.01 J to 6.43 J at quality 6 and is still above the float decode's 1.28 J by that count. Host B's integer decode was measured before and after, without a float decode beside it. The scripts that took the readings are in runs/; decode-throughput.md notes the new sets; the changelog records the change. Co-Authored-By: Claude Opus 5.5 <[email protected]> |

The scripts that took the record's readings
Each ran on one host, from a checkout of the change that added the record (the build host
through the repository's remote-build wrapper, which sets RB_ROOT and runs in the
checkout; the two Linux hosts from a copy of wai/ in ~/wai-build/det1/src or
~/det1/src). The work directory they read and write is the one
tools/wai_determinism_cost.py lays out; its sets/, int/, float/, src/,
pictures.json and models.json were made once, on the build host, and copied to the
other two.
| script | host | what it ran |
|---|---|---|
macos-build.sh |
build host | the integer decoder for the CPU, for the GPU (ops_gpu) and for wasm32-wasip2 |
macos-decodes.sh |
build host | cpu, gpu, wasm: the integer decodes; float: the float decodes |
macos-energy.sh |
build host | the timed runs, with the per-task count and the GPU rail |
linux-a-decodes.sh |
x86_64 host A | int, float: the decodes on its CPU and its integrated GPU |
linux-a-energy.sh |
x86_64 host A | the timed runs, with the package counter |
linux-a-wasm.sh |
x86_64 host A | the build host's wasm32-wasip2 decoder under wasmtime on x86_64 |
linux-b-decodes.sh |
x86_64 host B | int, float: the decodes on its CPU and its discrete GPU |
macos-narrow-build.sh |
build host | §4.6: the integer decoder of the narrow kernel sets, for the CPU, the GPU and wasm32-wasip2 |
macos-narrow-decodes.sh |
build host | §4.6: its decodes with each kernel set (neon, neon1 on one core, wide), on the GPU and as wasm32-wasip2 |
macos-narrow-energy.sh |
build host | §4.6: the timed runs, -before, -after and -again, with the per-task count |
linux-a-narrow-jobs.sh |
x86_64 host A | §4.6: the job lists of that host's work directory |
linux-a-narrow-build.sh |
x86_64 host A | §4.6: the integer decoder for the CPU and the GPU |
linux-a-narrow-decodes.sh |
x86_64 host A | §4.6: its decodes with each kernel set, on the GPU, and the build host's wasm32-wasip2 file |
linux-a-narrow-energy.sh |
x86_64 host A | §4.6: the timed runs, with the package counter |
linux-b-narrow-decodes.sh |
x86_64 host B | §4.6: the build, then the decodes with each kernel set |
linux-b-narrow-energy.sh |
x86_64 host B | §4.6: the timed runs of the integer decode, with the package counter |
The record names each platform by the tag its script wrote: macos-arm64-… for the build
host, wasm32-wasip2 for the WebAssembly build there (wasm32-wasip2-x86_64 for the same
.wasm on host A), linux-x86_64-… for host A and
linux-x86_64-b-… for host B.
On the build host the float and wasm steps ran detached, under the host's memory
guard, beside the other steps: the float decodes from a copy of the checkout's
tools/wai_determinism_cost.py and the export tool it imports, the same bytes.
The §4.6 scripts ran from a checkout of the change that added the narrow kernel sets, in the
same way: the build host through the remote-build wrapper, in $RB_ROOT/idf, reading the
record's work directory there; the Linux hosts in ~/wai-build/idf and ~/idf, from a copy
of wai/ and of the work directory's sets/, int/, float/ and pictures.json. Each
host's bin/base (on the build host, the record's own det1/bin/wai_det_cost.native) is
the record's commit built the same way, which the -before runs time. The tags of §4.6 end
in -isa-<kernel set>.
