Welcome to the homepage for our latest software - KLMC. KLMC, or more specifically the Knowledge Led Master Code, was created with the desire to: automate many tasks traditionally performed by the user of a range of third party codes (listed below in the right hand column); enable a multistage approach where the KLMC code learns on the fly and refines input files that are submitted for new calculations - hence the name knowledge led; and be able to exploit massively parallel computer platforms for a more general set of applications that may require statistical sampling. The KLMC code is witten in Fortran90 and uses MPI to simultaneously exploit more than one processor.
Applications include: (a) Simple task farming (screening structures from the database through a third party code); (b) Structure prediction of nano-sized clusters in vacuum or on a surface; structure prediction of bulk phases; and structure prediction of surface reconstructions - using a range of global optimisation techniques based on basin hopping and genetic algorithms; And (c) statistical sampling of solid solutions or multiple point defects in a crystalline solid.

We also acknowledge the use of local HPC facilities - namely, Legion - which is provided by UCL.
