+The information included in this page has been updated on *November 2016* and it is valid for the release version 0.6.0.
+
+
+The following configuration is recommended for the [Intel Knights Landing](http://ark.intel.com/products/codename/48999/Knights-Landing) platform:
+
+``` text
+../configure --enable-precision=double\
+             --enable-simd=KNL        \
+             --enable-comms=mpi3-auto \
+             --with-gmp=<path>        \
+             --with-mpfr=<path>       \
+             --enable-mkl             \
+             CXX=icpc MPICXX=mpiicpc
+```
+
+where `<path>` is the UNIX prefix where GMP and MPFR are installed. If you are working on a Cray machine that does not use the `mpiicpc` wrapper, please use:
+
+``` text
+../configure --enable-precision=double\
+             --enable-simd=KNL        \
+             --enable-comms=mpi3      \
+             --with-gmp=<path>        \
+             --with-mpfr=<path>       \
+             --enable-mkl             \
+             CXX=CC CC=cc
+```
+
+
+#### Notes
+- [GMP](https://gmplib.org/) is the GNU Multiple Precision Library.
+- [MPFR](http://www.mpfr.org/) is a C library for multiple-precision floating-point computations with correct rounding.
+- Both libaries are necessary for the RHMC support.
