What is SIESTA?

SIESTA (Spanish Initiative for Electronic Simulations with Thousands of Atoms) is both a method and its computer program implementation to perform efficient electronic structure calculations and ab initio molecular dynamics simulations of molecules and solids.


Siesta in parallel mode is supported in our cluster systems. Users should use the following command to setup required environment variables:

System Siesta version Command
HPC2015 3.2 module load siesta/impi

To execute the parallel version of siesta:

mpirun -np N siesta < input.fdf > output

where N is number of processors, input.fdf is the SIESTA input file and output is the name of the output file.

Sample programs and pbs script are available at /share1/siesta/sample/.
