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 unknown errors; as well as
parallel versions (OpenMP, Fork, MPI and Global Arrays) for almost all kind of jobs.

Parallel computing

The Turbomole Module subsumes all available parallel computing variants of Turbomole's binaries. Turbomole defines the following parallel computing variants:

SMP = Shared-memory parallel computing based on OpenMP and Fork() with the latter using separated address spaces.
MPI = Message passing interface protocol based parallel computing
GA = Global arrays, API for "shared-memory" programming for distributed-memory computers which can be used e.g. to complement MPI.

However only one of the 3 parallel variants or the sequential variant can be loaded at once and most Turbomole's binaries support only 1 or 2 of the parallelization variants. Like for Turbomole installations without a Module system, the variants have to be triggered by the environment variable $PARA_ARCH.

Usage

Before loading the Module

Before loading the Turbomole Module the parallel computing variant has to be defined via the environment variable $PARA_ARCH using the abbreviations SMP, MPI or GA, e.g.:

$ export PARA_ARCH=MPI

will later load the MPI binary variants. If the variable $PARA_ARCH is not defined or empty, the sequential binary variants will be active once the Turbomole Module is loaded.

Loading the Module

You can load the default version of Turbomole with the command:

$ module load chem/turbomole

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

$ module load chem/turbomole/6.5

to load the version 6.5

Switching between different parallel variants

To switch between the different parallel variants provided by the Turbomole Module, simply define the new parallel variant via $PARA_ARCH and load the Module again. Note that for switching between the parallel variants unloading of the Turbomole Module is not required. For instance to change to the MPI variant, execute:

$ export PARA_ARCH=MPI
$ module load chem/turbomole

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

Single node jobs

Template provided by Turbomole Module

The Turbomole Module provides a simple Moab example of Cubane (C8H8) that runs an energy relaxation via MPI parallel dscf using 4 cores on a single node and its local file system. To simply run the example do the following steps:

$ module load chem/turbomole
$ mkdir -vp ~/Turbomole-example/
$ cd ~/Turbomole-examples/
$ cp -r $TURBOMOLE_EXA_DIR/* ~/Turbmole-example/
$ msub bwHPC_turbomole_single-node_example.sh

The last step submits the job example script bwHPC_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.

Geometry optimization

To do a geometry optimization of the previous job example modify bwHPC_turbomole_single-node_example.sh by replacing the following line

time dscf > dscf.out 2>&1

with

time jobex -dscf -keep 2>&1

and submit the modified script to the queueing system via msub. The Turbomole command jobex controls the call of all the required Turbomole binaries for the geometry optimization.

Turbomole-Specific Environments

To see a list of all Turbomole environments set by the 'module load'-command use 'env | grep TURBO'.

Preparing a calculation and using the queueing system:
--------------------------------------------------------------------------------
* Each turbomole job must run in it's own directory (a new dir for each job).
* Usually the input files 'basis', 'control', 'coord' and 'mos' must exist in
the current directory before you can run the turbomole commands like 'dscf'.
* The input files can be created either via:
a) command line tool 'define' (as described in 'Tutorial_6-6.pdf') or
b) graphical user interface 'TmoleX' (as described in
'Tutorial-tmolex-4-0.pdf').
Please only construct and save jobs ('Save' button) via 'TmoleX',
but do not use the 'Run'-job buttons (since they do not
work properly). Furthermore you can extract the Turbomole commands
(e.g. 'dscf', 'jobex', ...) of your job from file 'start-job' saved
by TmoleX and paste these commands into your queueing system script.
* Thereafter you can run the quantum chemistry calculations interactivley,
e.g. by calling the hartree fock SCF command 'dscf' in your interactiv login
shell. You can monitor the memory consumption or debug your input. Example:
cp -v /opt/bwhpc/common/chem/turbomole/6.6_tmolex40/bwhpc-examples/{coord,*basis,control,mos} ./
time dscf > dscf.out
* Finally you can submit a series of these Turbomole commands in a batch script
to the queueing system. An example for such a script can be found here:
/opt/bwhpc/common/chem/turbomole/6.6_tmolex40/bwhpc-examples/bwHPC_turbomole_single-node_example.sh
The example includes many comments and detailed instructions
on how to submit Turbomole jobs to the queueing system.
Please carefully work through the example script.
* For more information on job submit script please visit:
http://www.bwhpc-c5.de/wiki/index.php/Batch_Jobs

Using third party tools and turbomole variants:
-------------------------------------------------------------------------------
* The commands 'calculate', 'mole' (package MoleControl) and 'thermocalc'
are available on command line after loading the turbomole module.
For details see the pdf files referenced above. Examples:
cp -v /opt/bwhpc/common/chem/turbomole/6.6_tmolex40/bwhpc-examples/{ammonia.xyz,methane.xyz,calculate.inp} ./
calculate -l calculate.inp -m AM1-COSMO > calculate.out 2>&1
thermocalc -l calculate.inp -m ta > thermocalc.out 2>&1

Using HUGE binaries of turbomole:
-------------------------------------------------------------------------------
* In addition a '*_huge' variant of most Turbomole commands is
available after loading this module. This variant is intended for
very huge calculations (e.g. when 'define' complains
about 'limits are too low'). For details on '_huge' limits see
/opt/bwhpc/common/chem/turbomole/6.6_tmolex40/documentation/README_howto_use_huge

Selecting a different Turbomole version (e.g. a parallel version):
-------------------------------------------------------------------------------
* By default
module load chem/turbomole
loads the serial version of Turbomole _without_ TmoleX support and
module load chem/tmolex
loads the serial version of Turbomole _with_ TmoleX support.
* If you want to use the shared memory parallel SMP version, you have to execute
export PARA_ARCH=SMP
_before_ calling the 'module load' command given above. In case of the message
passing inferface (MPI) version, you have to execute
export PARA_ARCH=MPI
instead. The best PARA_ARCH depends on the Turbomole command you are planning
to use. Please benchmark your jobs to find the optimal PARA_ARCH and PARNODES
values before submitting mass jobs. Please read chapter 6.11 'Parallel runs'
in 'Tutorial_6-6.pdf' and chapter 3.2 'Parallel Runs' in 'Documentation.pdf'
for a list of binaries and their parallelization.
* You can control the number of threads via environment variable PARNODES, e.g.
export PARNODES=2
You should set PARNODES in accordance with the number of requested
cores in the queueing system (for details see pbs example script above).

Toubleshooting (possible problems and solutions):
-------------------------------------------------------------------------------
* If you did login via ssh, X11 forwarding must be enabled for TmoleX.
E.g. login to current host via command 'ssh -X -l kn_pop235844 uc1n997'.
* Please be aware that TmoleX via X-forwarding is very slow.
But you can download your own private copy of TmoleX (see above).
* Please load a newer Python and NumPy module if you see error messages like
Minimum requirement of MoleControl is Python Version 2.6.2 final
while using MoleControle (command 'mole').

Further software usage hints and conditions:
-------------------------------------------------------------------------------
* Please cite Turbomole in publications according to Turbomole documentation.
* The variables and commands are available after loading 'chem/turbomole/6.6'.
* In case of problems, please contact 'robert.barthel@kit.edu'.
