Anthropic Engineer Shares Trainium Chip Trace

Daniel Liu, Member of Technical Staff on Anthropic's kernels team, posted a tweet containing a video attachment. The video shows a detailed instruction profile trace from one trn2 NeuronCore on a Trainium chip, with labeled timelines for Tensor-sequencer, Scalar-sequencer, Vector-sequencer, QpSimd, and Sync. The post text references a bad apple running on the Trainium chip. The tweet is the sole source of this information in the packet.
