Now, we build flexi once without instrumentation. Preparationįirst we clone flexi and create a build git clone cd mkdir cd build/ We used the input files given here: flexi_input.zip. You might use other compilers and MPI versions. Furthermore, we use the Intel Compiler Suite and Intel MPI during this test case.

This tutorial assumes that you installed the READEX components and have their binaries available at $PATH. In this tutorial, we show, how flexi is instrumented and optimized with READEX, which results in energy savings of 11 %.

Flexi is a High Perfomance Open Source CFD that scales to hundreds of thousands of processor cores.
