Aplikacija se širi hibridno procesima (MPI paradigma) i dretvama (OpenMP paradigma). Varijabla okruženja OMP_NUM_THREADS definira koliko dretvi će svaki MPI proces kreirati. Iz tog razloga umnožak procesa i dretvi mora odgovarati zatraženom broju slotova definiranim u paralelnom okruženju. U primjeru je to 16 = 4 (MPI procesa) x 4 (OpenMP dretve) |
Instalacija
Programski paket SIESTA je pripremljen s kompajlerom Intel 2019, Intel MKL Scalapack i MPI implementacijom OpenMPI 3.0.0. Instalacija je obavljena pripremom pomoćnih biblioteka na koje se paket oslanja, dopremanjem izvornog koda, učitavanjem potrebnih modula za kompajler i MPI paralelizaciju te kompajliranjem samog paketa.
