One of our main activities is the development of the massively parallel QMC code QMC=Chem.
Contents
Current Features
Methods
- VMC
- DMC
- Jastrow factor optimization
- CI coefficients optimization
Wave functions
- Single determinant
- Multi-determinant
- Multi-Jastrow
- Nuclear cusp correction
Properties
Practical aspects
- Very low memory requirements
- Runs on a large number of processors : tested on 512 processors at the CALMIP cluster, and on 1000 processors on the EGEE European grid.
- Checkpointing
- Fail safe : if the code is aborted, the data is kept. This feature is very useful in grid environments.
- Easy development with the IRPF90 tool.
- Documentation
Features under development
Properties
- Molecular Forces
- Moments (dipole, quadrupole,...)
- Electron density
- ZV-ZB EPLF estimator
Practical aspects
- Graphical interface for input and output
Input file creation
The QMC=Chem input file can be created using the web interface. Upload a Q5Cost file or an output file from GAMESS, Gaussian or Molpro, and you will download the QMC=Chem input directory.
