share of Meta Llama 3 unexpected training interruptions from faulty GPUs / HBM3 memory (148 and 72 of 419)

35.3% / 17.2%derived

Value kindderived — Derived values are guide calculations; their result is only as fixed as the stated inputs, scope, and method.
ScopeOne 54-day pre-training window on a 16,384-GPU H100 cluster — a single fleet, generation, and workload, not an industry rate.
CaveatGuide arithmetic on the paper's own counts. Table 5's 18 rows sum to 419, but its printed percentages sum to 94.9%, so no denominator reproduces them; use the counts.
