Description
In this paper we describe different applications we have ported to Intel Xeon Phi architectures, analyzing their
performance. The applications cover a wide range. Alya, which is an HPC-based multi-physics code for parallel
computers capable of solving coupled engineering problems in non-structured meshes. Waris, which is a simulation
code for Cartesian meshes, that uses efficiently well-ordered data and well-balanced parallel threads. The last analysis
is performed for a cornerstone of several simulation codes, a Cholesky decomposition method. The results are very
promising, showing the great flexibility and power of Xeon Phi architectures.
