Reverts InferenceMAX/InferenceMAX#348


Note

Reverts MI355x disaggregated SGLang support and related CI/configs; consolidates MI355x runner to single-node path and updates GB200 Dynamo script.

  • Remove dsr1-fp8-mi355x-sglang-disagg from amd-master.yaml
  • Delete benchmarks/dsr1_fp8_mi355x_sglang-disagg_slurm.sh
  • Simplify runners/launch_mi355x-amd.sh to single-node salloc/srun; drop multinode/disagg orchestration and log collection
  • Prune corresponding entry from perf-changelog.yaml
  • Minor: update benchmarks/dsr1_fp8_gb200_dynamo-sglang_slurm.sh (env var checks, Dynamo clone/submit flow)

Summary of Changes

Hello @cquil11, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request performs a complete revert of a previous change (InferenceMAX/InferenceMAX#348) that introduced a CI workflow for AMD MI355X distributed inference tests. The revert removes all associated configuration, benchmark scripts, and runner logic, effectively undoing the integration of these specific tests from the system.

Highlights

  • Configuration Removal: The configuration for the dsr1-fp8-mi355x-sglang-disagg distributed inference test workflow has been removed from .github/configs/amd-master.yaml.
  • Benchmark Script Deletion: The dedicated benchmark script benchmarks/dsr1_fp8_mi355x_sglang-disagg_slurm.sh, which handled the setup and execution of SGLang distributed inference benchmarks for MI355X, has been deleted.
  • Runner Script Simplification: The runners/launch_mi355x-amd.sh script has been simplified by removing the multi-node specific logic and the scancel_sync function, effectively reverting its capability to launch multi-node SGLang distributed inference benchmarks.
  • Changelog Update: The corresponding entry for the dsr1-fp8-mi355x-sglang-disagg configuration has been removed from perf-changelog.yaml.

Code Review

This pull request reverts the changes from PR #348, removing the mi355x distributed inference test CI workflow. The changes correctly remove the configuration from amd-master.yaml, delete the dsr1_fp8_mi355x_sglang-disagg_slurm.sh benchmark script, prune the perf-changelog.yaml, and simplify runners/launch_mi355x-amd.sh to a single-node path.

My review found one issue: an extra newline was added at the beginning of benchmarks/dsr1_fp8_gb200_dynamo-sglang_slurm.sh, which misplaces the shebang and can cause execution problems. I've added a comment with a suggestion to fix this. Otherwise, the revert appears to be correct and complete.

high

The shebang (#!/bin/bash) must be on the very first line of a shell script. The added blank line at the beginning of the file can cause the script to be executed by the wrong interpreter if run directly, which can lead to errors. Please remove the leading blank line.

Empty line before shebang breaks script execution

Medium Severity

This revert accidentally adds an empty line before the shebang (#!/bin/bash), moving it from line 1 to line 2. The shebang must be on the first line of the file for the kernel to recognize the script interpreter when executed directly. While this script may still work when invoked explicitly with bash, direct execution (e.g., ./script.sh) will fail or behave unexpectedly.
