Parallel implementation of electronic structure eigensolver using a partitioned folded spectrum method
E. L. Briggs, C. T. Kelley, J. Bernholc
A parallel implementation of an eigensolver designed for electronic structure calculations is presented. The method is applicable to computational tasks that solve a sequence of ei…
