SAMG for groundwater simulation: mesh-agnostic yet fast

The SAMG software package for the solution of large linear systems of equations with sparse matrices has proven to be highly efficient for groundwater simulation. Compared with classical solvers, the benefit of SAMG grows with the size of the systems of equations to be solved because the computational cost of SAMG increases only linearly with the number of unknowns. SAMG is applicable for structured and unstructured meshes and supports both multi-core and multi-node systems.

Accelerating MODFLOW with the enhanced SAMG linear solver software

SAMG is a software package for the highly efficient numerical solution of large sparse matrix problems. These problems occur in application areas such as fluid flow, structural mechanics, oil reservoir and ground water simulation, casting and molding, process and device simulation in solid state physics and circuit simulation. SAMG's solver modules incorporate modern hierarchical techniques (algebraic multigrid, AMG), making them especially suitable for solving large classes of discretised elliptic differential equations. Compared to classical solution methods, SAMG's solver modules have a major advantage in that they are numerically scalable. That is, the computational cost is only linearly proportional to the number of unknowns.

Simulation and optimization of data center energy flows

The reduction of energy consumption and the possible reuse of waste heat become increasingly important issues in the design and operation of large data centers. The increased variability in the energy consumption of HPC data centers is a great challenge for the current center infrastructure, which is mainly driven by the need to save electrical energy. Figure 2 shows the power consumption of the Leibniz Supercomputing Centre of the Bavarian Academy of Sciences and Humanitiesin Garching (LRZ). As can be seen, the overall power consumption varies with the power consumption of the super computer (SuperMUC). The combination of this load variability and the use of new cooling technologies in the data center (chillerless cooling) provides an opportunity to increase the energy efficiency of the data center.
