4. 3. Parallelization of dynamic algorithms for electronic structure calculations

   Författare :Anton G. Artemov; Emanuel H. Rubensson; Maya Neytcheva; Bo Kågström; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; parallelization; task-based programming; matrix algorithms; sparse matrices; inverse factorization; localized computations; density matrix methods; electronic structure calculations; Scientific Computing; Beräkningsvetenskap;

   Sammanfattning : The aim of electronic structure calculations is to simulate behavior of complex materials by resolving interactions between electrons and nuclei in atoms at the level of quantum mechanics. Progress in the field allows to reduce the computational complexity of the solution methods to linear so that the computational time scales proportionally to the size of the physical system. LÄS MER

5. 4. Automatic and Explicit Parallelization Approaches for Equation Based Mathematical Modeling and Simulation

   Författare :Mahder Gebremedhin; Peter Fritzson; Erwin Laure; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Modelling; Simulation; Multi-core; Automatic Parallelization; Clustering; Scheduling; Explicit Parallelization; ParModelica; Task Systems; GPGPU;

   Sammanfattning : The move from single-core processor systems to multi-core and manyprocessor systems comes with the requirement of implementing computations in a way that can utilize these multiple computational units efficiently. This task of writing efficient parallel algorithms will not be possible without improving programming languages and compilers to provide the supporting mechanisms. LÄS MER

7. 5. Automatic Parallelization of Equation-Based Simulation Programs

   Författare :Peter Aronsson; Peter Fritzson; Christoph Kessler; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Heavy-duty simulation; Parallel computers; Automatic parallelization; Clustering; Computer science; Datavetenskap;

   Sammanfattning : Modern equation-based object-oriented modeling languages which have emerged during the past decades make it easier to build models of large and complex systems. The increasing size and complexity of modeled systems requires high performance execution of the simulation code derived from such models. LÄS MER
