Description
This report summarizes the results of the scalability improvements of the algorithms used in Total FETI
(TFETI). A performance evaluation of two new techniques is presented in this report: (1) a novel pipelined
implementation of CG method in PETSc and (2) a MAGMA LU solver running on following many-cores
accelerators: GPU Nvidia Tesla K20m and Intel MIC Xeon Phi 5110P.
