Title
Comparison of Selected FETI Coarse Space Projector Implementation Strategies
Abstract
•Two new strategies for the solution of FETI coarse problem.•Significant improvement of FETI scalability (up to 4.8 speedup for the largest benchmark containing 27,000 subdomains).•Experimental results giving a guide for selecting partial parallelization parameters.
