Atomistic simulation requires three things: knowledge of the science, compute-efficient implementation of simulations, and accessible interfaces to the simulation stack.

The first remains the researcher’s domain, as no tool substitutes for knowing what to simulate or recognizing a physically meaningful result. NVIDIA ALCHEMI Toolkit, introduced earlier this year, has dramatically reduced the second barrier for Machine Learning Interatomic Potentials (MLIP) with composable, PyTorch-native building blocks for constructing GPU-accelerated simulation workflows with in-flight batching enabled.

The third barrier has persisted. Unlike classical force fields, the MLIP ecosystem is still nascent, and the accessible interfaces that exist for classical simulations are very limited.…
