TURBOMOLE®

TURBOMOLE pioneered the development of quantum chemistry methods to accurately model real life applications with acceptable computational cost.

A parallel MPI version of the most important modules was implemented in the mid-90s on an IBM RS6000 cluster. The extremely efficient serial code was parallelized to gain a reasonable speedup on a limited number of CPUs, and was extended to run on a massively parallel system later on.

A simple-to-use new parallelization for SMP and multi-core systems has been developed in recent years, which enables low run times on typical and cheap standard PCs as well as on high-performance NUMA systems with hundreds of CPUs.

A  list of some typical runs on a modern PC running a standard Linux distribution which covers some of the most frequently used tasks can be downloaded HERE

TmoleX is our easy to use graphical user interface to quickly handle TURBOMOLE calculations. While quantum chemistry suites have traditionally been developed for a command line or script based use (aiming at power users), TmoleX allows you to do quantum chemistry after a few minutes of introduction. It is the perfect tool for occasional TURBOMOLE use.

The TmoleX Client version can be used to submit jobs to a remote Linux server without having a complete TURBOMOLE installation:

• TmoleX Client Windows version
• TmoleX Client MacOS version
• TmoleX Client Linux version

Job handling / usability

• Start single molecule jobs locally or on a remote server
• Start multi molecule batch jobs locally and remotely. A defined standard calculation procedure (job template) will be used for all molecules.
• Define and modify job templates (basis set, method, kind of job, etc.) for later use with single molecule jobs or batch jobs.
• Simple built-in queuing system for local and remote jobs. By defining the number of usable CPUs, TmoleX will submit jobs until all allowed CPUs are put to work. Further jobs will be queued to wait for free CPUs.

Import / Export and visualization
