GaspiLS is a scalable and industry proven linear solver library for the exascale age. Many engineering simulations are based on CFD and FEM methods. Examples are the determination of aerodynamic properties of planes or the analysis of statics of buildings. A large part of the computation time is required to solve the underlying equations using iterative methods. The performance of the employed iterative solvers has a significant impact on the total run time of these simulations. We have developed the linear solver library GaspiLS to faster gain insights from the simulations.
Industry uses GaspiLS for better scalability
Scalability measures the parallel efficiency of an implementation. The optimum is the so-called linear scalability. This corresponds to a full utilization of the cores within a single CPU or the CPUs within a cluster, which are interconnected by a network.
GaspiLSs' inherent scalability yields the following advantages for simulations:
- more detailed models
- more precise parameter studies
- cost-efficient resource utilization
These aspects make GaspiLS particularly interesting for industry.
