Gaussian 16 Revision C.01 Jun 2026
In the realm of computational chemistry, few software packages command the respect and widespread adoption of Gaussian. Since its inception, Gaussian has been a cornerstone for researchers modeling molecular electronic structures, reaction pathways, spectroscopic properties, and numerous other quantum chemical phenomena. With each successive version and revision, the software undergoes refinement—bug fixes, performance enhancements, and the introduction of new algorithms.
It is important to note that while Gaussian 16 supports GPU acceleration (NVIDIA K40, K80, P100, V100), the GPU acceleration is primarily tuned for specific parts of the code, such as DFT energies, gradients, and frequencies for closed-shell systems. Revision C.01 optimizes memory transfer between the host CPU and the GPU, minimizing the bottleneck of PCIe data transfers. 4. Practical Implications for Computational Workflows
When using Gaussian 16 Revision C.01 to produce scientific results, it is standard and required practice to cite the software in resulting publications. Gaussian, Inc. provides a specific citation format for Revision C.01:
Gaussian 16 Revision C.01 is a significant upgrade from its predecessor, Gaussian 09. This revision includes a range of new features, improvements, and bug fixes. Some of the key highlights include: gaussian 16 revision c.01
Whether you are studying small organic molecules or large protein-ligand complexes, Revision C.01 provides the robust toolset necessary for modern computational workflows. Key Enhancements in Revision C.01
From my perspective, Gaussian 16 Rev. C.01 stands out as a particularly robust and well-rounded release. While revisions that follow might target niche hardware, Rev. C.01 offered a generous suite of new theoretical methods alongside broad hardware support, making it a valuable tool for a very wide range of researchers.
Perhaps most importantly for users migrating from Revision B.01, a critical issue related to the Gaussian-4 (G4) thermochemistry protocol was resolved. Users had reported erratic results for G4 calculations in the B.01 revision. The recommended fix was to use either the older Revision A.03 or the newer Revision C.01, highlighting the C.01's status as a crucial stability update. In the realm of computational chemistry, few software
Revision C.01 introduced substantial performance improvements across all supported GPU types, including the earlier K40, K80, and P100 (Pascal) boards. Stability:
: Utilities such as formchk gained a new -m command-line argument, allowing users to explicitly specify the memory available to the utility (e.g., formchk -m=1gb ). New Computational Features & Refinements
Gaussian 16 Revision C.01: Enhanced Performance for Computational Chemistry It is important to note that while Gaussian
By retaining the vast amplitude data structures inside active system RAM rather than writing scratch files to local disks, it circumvents physical storage speed limits and heavily accelerates post-Hartree-Fock jobs. 📊 Core Feature Matrix: Gaussian 16 vs. Gaussian 09
Gaussian 16 Rev. C.01 stands as a noteworthy milestone in the software's history, offering significant advancements in both functionality and performance. While later revisions have brought support for newer hardware, Rev. C.01 remains a powerful and widely-used workhorse in computational chemistry labs around the world.
is specified. For example, you can now force the program to recompute connectivity or use standard orientation from a checkpoint file. Saddle Point Management: New options like Opt=NGoDown
Enhanced convergence stability for tight optimization criteria, especially in complex potential energy surfaces (PES) or floppy molecules.
