Description

Turbomole is a general purpose quantum chemistry software package for ab initio electronic structure calculations and provides:

• ground state calculations for methods such as Hartree-Fock, DFT, MP2, and CCSD(T);
• excited state calculations at different levels such as full RPA, TDDFT, CIS(D), CC2, an ADC(2);
• geometry optimizations, transition state searches, molecular dynamics calculations;
• property and spectra calculations such as IR, UV/VIS, Raman, and CD;
• approximations like resolution-of-the-identity (RI) to speed-up the calculations without introducing uncontrollable or unkown errors; as well as
• parallel versions (OpenMP, MPI and Global Arrays) for almost all kind of jobs.

Versions and Availability

A current list of the versions available on the bwUniCluster and bwForClusters can be obtained from the Cluster Information System: CIS Information on Turbomole

On the command line interface of any bwHPC cluster, a list of all available versions is generated by using

$ module avail chem/turbomole

Usage

Loading the module

You can load the default version of Turbomole with the command

$ module load chem/turbomole

The Module Turbomole does not depend on any other Module. Moreover, Turbomole provides its own libraries regarding OpenMP, MPI, Fork and Global Array based parallelization. If you wish to load a specific (older) version you can do so using e.g.:

$ module load chem/turbomole/6.5

to load the version 6.5

Program Binaries and Scripts

The Turbomole software package consists of a set of stand-alone program binaries providing different features and parallelization support:

Disk Usage

By default, scratch files of Turbomole binaries are placed in the directory of Turbmole binary execution. Please do not run your Turbomole calculations in your $HOME or $WORK directory.

Examples

You can copy a simple MOAB example to your home directory and run it, by doing the following steps:

$ mkdir -vp ~/Turbomole-example/
$ cd ~/Turbomole-examples/
$ cp -r $TURBOMOLE_EXA_DIR/* ~/Turbmole-example/
$ msub bwUniCluster_turbomole_single-node_example.sh

The last step submits the job example script bwUniCluster_turbomole_single-node_example.sh to the queueing system. Once started on a compute node, all calculations will be done under an unique directory on the local file system of that particular compute node.

Version-Specific Information

For specific information about version X, see the information available via the module system with the command

$ module help chem/turbomole/X
