Gaussian 16W supports shared-memory parallelism (SMP). It can utilize multi-core processors and large RAM allocations (beyond the 2GB limitation of older 32-bit versions). Users can define the number of processors ( %NProcShared ) and memory usage ( %Mem ) in the Link 0 section of the input file to optimize hardware usage.
Locates stable molecular geometries and transition states.
Includes Amber, DREIDING, and UFF force fields for quick geometries or modeling massive biomolecules.

energy cycles fluctuate, then gradually narrow down toward a single, stable value. Gaussian.com Gaussian 16W Reference 14 Aug 2016 —
Gaussian 16 has a wide range of applications in various fields, including:
For small systems, adding more cores can actually decrease performance due to inter‑core communication overhead. One benchmark showed that doubling from 2 to 4 cores on a small semi‑empirical calculation increased wall time from 1 minute 9 seconds to 1 minute 21 seconds. Gaussian 16W supports shared-memory parallelism (SMP)
Gaussian 16W offers an expansive suite of quantum mechanics (QM) methods, molecular mechanics (MM), and hybrid approaches. 1. Electronic Structure Methods
Some of the new features in Gaussian 16 include:
Gaussian 16W serves as a bridge between theoretical physics and practical chemistry. It allows researchers to model stable molecules, reactive intermediates, and transition states without the need for physical synthesis. The "W" variant packages the powerful Gaussian computational core (Linux-based origin) into a Windows-compatible environment, complete with the GaussView interface integration, making high-level quantum mechanics accessible on desktop workstations.
