Fixes #482

Summary

Adds the reference RCP entry qwen35_397b_grpo_ref_1152 (BS = 1152, 6912 samples) to mlperf_logging/rcp_checker/training_6.1.0/rcps_qwen35_397b_grpo.json in accordance with the qwen35_397b_grpo benchmark scaling and evaluation formulas:

  • BS = 1152 (num_prompts_per_step = 72, num_generations_per_prompt = 16)
  • opt_base_learning_rate = 2.1213203436e-6 (1e-6 * sqrt(1152 / 256))
  • opt_gradient_clip_norm = 0.05892556510 (0.125 * sqrt(256 / 1152))
  • Epochs to converge = [6912, 6912, 6912, 6912, 6912, 6912] (1152 * ceil(2.5 + 3840 / 1152) = 6912)

Reference codebase doesn't support tpu7x

Offline discussion confirmed that this wasn't generated using the reference code so it cannot be merged until the reference also shows similar convergence.

@susanbao if this is deprecated in favor of #485 can we close this?
