    • Scalability analysis of Dalton, a molecular structure program 

      Aguilar, Xavier; Schliephake, Michael; Vahtras, Olav; Giménez Lucas, Judit; Laure, Erwin (Elsevier, 2013-10)
      Article
      Accés restringit per política de l'editorial
      Dalton is a molecular electronic structure program featuring common methods of computational chemistry that are based on pure quantum mechanics (QM) as well as hybrid quantum mechanics/molecular mechanics (QM/MM). It is ...
    • Scalability prediction for fundamental performance factors 

      Rosas Mendoza, Claudia; Giménez Lucas, Judit; Labarta Mancho, Jesús José (2014-06)
      Article
      Accés obert
      Inferring the expected performance for parallel applications is getting harder than ever; applications need to be modeled for restricted or nonexistent systems and performance analysts are required to identify and extrapolate ...
