Benefits: You can use a scalable thread-parallel implementation of modal steady-state dynamic analysis to reduce the analysis time on shared memory parallel machines.
Description: A scalable thread-parallel implementation of modal steady-state dynamic analysis that uses the high-performance SIM architecture significantly reduces the analysis time on shared memory parallel machines. The parallel solver is available for the symmetric, unsymmetric, and coupled structural-acoustic frequency response analyses. Both mode-based and subspace-based procedures are supported.
Table 6–3 shows the performance of a scalable thread-parallel steady-state dynamic solver. The analysis is based on 10,000 eigenmodes, and the frequency sweep is performed at 500 points. The model includes material damping; thus, at every frequency point, a system of linear equations is solved. The presented analysis time includes only the solver time, and output is requested at only a few nodes. It is typical for a steady-state dynamic procedure based on a high number of modes that the time spent in other phases of the analysis is negligible. The presented results show very good parallel scaling up to 16 cores.
