What happened and what to do
Published on March 8, 2026, the page discusses practical FP4 training of large-scale Mixture-of-Experts models on Hopper GPUs. It identifies activation memory use and communication among experts during distributed training as relevant bottlenecks.
A company training models of this kind could instrument memory use and communication traffic at each stage, then build dashboards to track GPU utilization and performance. Those measurements can inform configuration changes and help prioritize optimizations without assuming that lower precision alone will resolve the bottlenecks.
How the consultancy can help
Wendelmaques can diagnose training memory use and communication costs, scope instrumentation, and implement monitoring pipelines and dashboards on the company’s infrastructure. The proposal can include operating the solution.
