Characterization of Xeon Phi with Linear Algebra Workloads

The efforts behind this independent study are to analyze how well suited Xeon Phi is for some frequently used linear algebra routines such as factorization and solvers. We are working with Intel MKL 11.1 on Xeon Phi based on KNC (MIC) architecture. The workloads under study include factorization and solving of dense and banded systems. Specifically, we are investigating the potential vectorization opportunities for such routines. The goal is to make use of all such opportunities that can help design hybrid banded spike-based solver.
