For ab-initio studies of the electronic and magnetic properties of
poly-atomic systems, such as molecules, crystals and surfaces.
Method of solution
The full-potential linearized augmented plane wave (FP-LAPW) method is
well known to enable accurate calculations of the electronic structure
and magnetic properties of crystals [2,3,4,5,6,7,8,9,10,11,12]. Within
the supercell approach it has also been used for studies of defects in
the bulk and for crystal surfaces.
Unusual features of the program
On IBM RS/6000 nodes part of the speedup was obtained by using an IBM
specific library [1]. (See Long Write-up, section 4.4.1).
