The local disk partition holding your GAUSS_SCRDIR has completely run out of storage space, or the file size has surpassed a file system limitation. gaussian 16 linux
Cause: Gaussian tries GPU acceleration but CUDA is missing. Fix: Disable GPU in input: %GPUCPU=0 or use %NoGPU .
Gaussian 16 officially supports:
Gaussian 16 is a powerful electronic structure modeling program for predicting the energies, molecular structures, vibrational frequencies, and chemical properties of molecules and reactions. While it is widely used in academic and industrial research, its effective operation on Linux—the most common platform for computational chemistry—requires careful attention to the operating system environment. This guide aims to provide a structured walkthrough of the entire process, from installation to performance tuning on a Linux cluster.

Apply the changes immediately by running: source ~/.bashrc Use code with caution. Understanding the Gaussian Input File Structure Fix: Disable GPU in input: %GPUCPU=0 or use %NoGPU
Provide superior core-count-to-price ratios. G16 handles high core counts efficiently, making modern AMD processors highly cost-effective for large throughput workloads. Memory (RAM) Architecture
