NVIDIA MLPerf v5.0: Reproducing Training Scores for LLM Benchmarks

NVIDIA has detailed the method for reproducing coaching scores from the MLPerf v5.0 benchmarks, particularly specializing in Llama 2 70B LoRA fine-tuning and Llama 3.1 405B pretraining. This initiative follows NVIDIA’s earlier announcement of attaining as much as 2.6x larger efficiency in MLPerf Coaching v5.0, as reported by Sukru Burc Eryilmaz on the NVIDIA weblog. The benchmarks are a part of MLPerf’s complete analysis suite geared toward measuring the efficiency of machine studying fashions.

Stipulations for Benchmarking

To run these benchmarks, particular {hardware} and software program necessities have to be met. For Llama 2 70B LoRA, an NVIDIA DGX B200 or GB200 NVL72 system is important, whereas the Llama 3.1 405B requires at the very least 4 GB200 NVL72 techniques related by way of InfiniBand. Moreover, substantial disk area is required: 2.5 TB for Llama 3.1 and 300 GB for LoRA fine-tuning.

Cluster and Surroundings Setup

NVIDIA makes use of a cluster setup managed by the NVIDIA Base Command Supervisor (BCM), which requires an surroundings based mostly on Slurm, Pyxis, and Enroot. Quick native storage configured in RAID0 is really useful to reduce knowledge bottlenecks. Networking ought to incorporate NVIDIA NVLink and InfiniBand for optimum efficiency.

Executing the Benchmarks

The execution course of entails a number of steps, beginning with constructing a Docker container and downloading essential datasets and checkpoints. The benchmarks are run utilizing SLURM, with a configuration file detailing hyperparameters and system settings. The method is designed to be versatile, permitting for changes based mostly on totally different system sizes and necessities.

Analyzing Benchmark Logs

Through the benchmarking course of, logs are generated that embody key MLPerf markers. These logs present insights into initialization, coaching progress, and last accuracy. The last word aim is to realize a goal analysis loss, which indicators the profitable completion of the benchmark.
