Best Post For Social Media Mafrketing TEGroupedLinear.is_first_microbatch resets to True after checkpoint resume, causing the first shared-layer call to overwrite main_grad instead of accumulating into it. When an MTP layer is reused across depths, this discards one depth’s gradient and makes resumed training differ from uninterrupted training. New Letter Drop Down

  • Before fix
Uninterrupted training retains: is_first_microbatch = False forward: depth 1 [False] → depth 2 [False] backward: depth 2 accumulates → depth 1 accumulates main_grad = grad(depth 2) + grad(depth 1) ✓ 
  • What is not expected after ckpt resume:
After checkpoint resume, the process-local flag resets: is_first_microbatch = True forward: depth 1 [True] → depth 2 [False] backward: depth 2 accumulates → depth 1 overwrites (beta=0) main_grad = grad(depth 1) ✗ └─ grad(depth 2) is discarded

  • Fixed
    Restore or initialize the state deterministically so resume matches uninterrupted training:
is_first_microbatch = False forward: depth 1 [False] → depth 2 [False] backward: depth 2 accumulates → depth 1 accumulates main_grad = grad(depth 2) + grad(depth 1) ✓

Frosted Business Cards Three-leg check — train-through to step 10 / save at 5 / resume from 5 — all legs in one allocation, comparing checkpoint shards byte for byte: How To Make A Blog Site

TEGroupedLinear.is_first_microbatch is process-local: True at construction, False after the first forward, and never written to a checkpoint. It is only re-armed per iteration for quantized configs, because set_is_first_microbatch is called from the fp8/fp4/kitchen paths. Transformer Engine derives the weight-gradient accumulation mode from it: accumulate = fuse_wgrad_accumulation and not is_first_microbatch so a stale True makes the wgrad GEMM overwrite main_grad with beta=0 instead of accumulating into it. That is harmless for a module invoked once per microbatch -- it overwrites a freshly zeroed buffer -- but destructive for one invoked twice, such as an MTP block sharing a layer across depths under --mtp-use-repeated-layer. Backward runs in reverse there, so the is_first=True invocation lands second and discards the other depth's contribution. The result is a checkpoint resume that is not bit-exact: a freshly loaded process has is_first_microbatch=True while a process that has been training has False, and only the fresh one corrupts its gradients. A run-to-run A/A check cannot detect this, because both fresh processes make the same mistake and agree. Add is_first_microbatch_tracked(config) next to set_is_first_microbatch, which returns whether the flag is actually maintained for this config, and pass None to TE when it is not. TE then falls back to its own accumulate decision rather than acting on a value nobody updates. Verified on a three-leg resume check (train-through vs save vs resume) at 2 and 64 nodes: without this the resumed leg diverges in grad norm one step after the resume; with it all checkpoint state shards are byte-identical.
