TeraChem is general purpose quantum chemistry software designed to run on NVIDIA GPU architectures under a 64-bit Linux operating system.

How to submit an input

To access the machine:

ssh username@10.3.1.200

To submit a job:

qs tchem1 inputfile.in
qs tchem145 inputfile.in
qs tchem150 inputfile.in

Input examples

Molecular dynamics

Output files

TeraChem creates an output file called name.out, it contains important information about energies, cycles convergence... but it does not contain the optimized geometry of optimizations or MD, nor the MO, ... this information can be found in the files included in the directory scr.

If you run two input files in the same directory the scr directory of the first will be overwritten by the last. For this it might be usefull to change the name of scr by filename_scr. This can be done in two different ways: by using "tchem150fmg" inestead of tchem150, or by using this script submit

Tests

  • File:Terachem.pdf Some tests on version 1.0, which does not have d orbitals or ECP's. Comparison was Gaussian09 with our 8 core machines vs (ii) Terachem with a single VGA Nvidia Geforce GTX-470 card.
