Key point
NVIDIA has disclosed an FP32 technique that accelerates MLIP molecular dynamics by up to 1.7x without retraining.
Details
- NVIDIA and EPFL researchers have disclosed a technique to accelerate FP32 matrix multiplications in MLIP using Tensor Cores without retraining
- When applying the BF16x9 technique on Blackwell GPUs, MD step speed improved by 1.70x in a 17,280-atom system, with accuracy at an energy error per atom level of 1.9e-10 to 1.6e-8 eV
- On Ampere and Hopper GPUs, applying the TF32x3 technique improved MD step speed by up to 1.49x, confirming advantages in physical stability and convergence compared to standard TF32
- Blackwell can be applied by simply setting an environment variable in the PyTorch 2.15.0 environment, while Ampere/Hopper require the implementation of a custom layer based on CUTLASS
