This paper presents experiences using Intel's KNL MIC platform on hardware that will be available in the Stampede 2 cluster launching in Summer 2017. We focus on 1) porting of existing scientific software; 2) observing performance of this software. Additionally, we comment on both the ease of use of KNL and observed performance of KNL as compared to previous generation "Knights Ferry" and "Knights Corner" Xeon Phi MICs [32]. Fortran, C, and C++ applications are chosen from a variety of scientific disciplines including computational fluid dynamics, numerical linear algebra, uncertainty quantification, finite element methods, and computational chemistry.
