Much of the pioneering work in applying parallel processing to large problems in computational chemistry is due to Enrico Clementi and coworkers, and the development of the LCAP parallel processing systems (see Ref. 90 and the numerous references therein). The LCAP (loosely coupled array of processors) project commenced in 1983, with the stated aim of coupling readily available commercial processors to form a system that is not massively parallel, but rather is modular and can be expanded to match the degree of parallelism that a set of applications can support. 

In the 1950s and 1960s, digital computers became available for calculations in quantum chemistry, but by today s standards, both the computers and the programming languages were extremely primitive. C.C.J. Roothaan devised a computer-adapted matrix form for the Hartree-Fock equations, but his early work with Enrico Clementi on the wave functions of atoms had to be done in a primitive form of machine language. 

While computational chemistry truly took off in the 1980s, it certainly was not all roses for those in the field. Not entirely surprisingly, with the tremendous increase in the accessibility of computers resulting from the explosive appearances of minicomputers and personal computers came new problems for computational chemistry. Enrico Clementi, an ab initio-ist who started IBM s computational chemistry research program in 1961 and worked for IBM until 1992, saw a reduction in the importance, if not the quality, of research as one result. He wrote ...
