CCPE – Paper Accepted for special issue

Paper accepted to a special issue of Concurrency and Computation: Practice and Experience (CCPE). This special issue will consist of extended versions of the best papers accepted by PPAM 2017. The title of the paper is “Parallel robust solution of triangular linear systems” Robust algorithms do not suffer from overflow and always return a valid result. In LAPACK eigenvectors (standard… Read more »
