Ginatempo, B. and Geist, G.A. and Stocks, G.M. and Shelton, W.A. and Bruno, E. (1991) A high performance code to calculate the electronic properties of metals and alloys. Accademia Peloritana dei Pericolanti, 69. pp. 61-82.
We report on an application code for the $ab initio$ calculation of electronic properties of multicomponent ordered and disordered solids. This code was awarded of the 1990 Gordon Bell Prize for the price/performance ratio. We briefly describe the multiple scattering based algorithm (KKR-CPA) underlying the code and analyse the reasons why this theory is computationally expensive but can be coded to exploit either distributed or shared memory supercomputers. Experimental runs on Intel iPSC/860, CRAY-YMP and other machines are presented and their performances compared. Furthermore both relativistic and non-relativistic applications on $N_i_0_._5 — Pt_0_._5$ alloy are presented together with a discussion of the interplay of disorder, relativity, and charge selfconsistency.
