Research direction

Read skainet-compile/skainet-compile-hlo/src/commonMain/kotlin/sk/ainet/compile/hlo/ConstantByteSerializer.kt and inspect the existing FP32, FP64, I32 and I64 serialization. Add little-endian serialization for FP16, BF16 and I8, with round-trip tests, then run ./gradlew :skainet-compile:skainet-compile-hlo:jvmTest. Done means all three dtype round-trip tests pass and the result is reported on the parent issue.

Description

coding size:s skill:kotlin-core sub-issue

Sub-issue of #1414 ([Feature]: Close the remaining NotImplemented stubs outside the operator surface).

Lane: 2 · Kotlin core
Skill needed: Kotlin; IEEE half/bfloat16 layout.
Size: s (a few hours)
Blocked by: nothing

What to do

  1. ConstantByteSerializer (skainet-compile/skainet-compile-hlo/src/commonMain/kotlin/sk/ainet/compile/hlo/ConstantByteSerializer.kt) only serializes FP32/FP64/I32/I64 and throws otherwise.
  2. Add FP16, BF16 and I8 little-endian serialization with tests; run ./gradlew :skainet-compile:skainet-compile-hlo:jvmTest.

Acceptance

  • Round-trip tests for the three dtypes pass
  • Result reported back on the parent issue

Notes

If something here turns out to be wrong or much bigger than the size label, comment on this issue or open a specific bug instead of blocking the parent.
