-----------------------------------------------------------------------------
The Long-Range Thread mode (LRT) in the Intel package currently uses
pthreads by default. If pthreads are not supported in the build environment,
the compile flag "-DLMP_INTEL_NOLRT" will disable the feature to allow for
builds without pthreads. Alternatively, "-DLMP_INTEL_LRT11" can be used to
build with compilers that support threads using the C++11 standard. When using
The Long-Range Thread mode (LRT) in the Intel package is enabled through the
-DLMP_INTEL_USELRT define at compile time. All intel optimized makefiles
include this define. This feature will use pthreads by default.
Alternatively, "-DLMP_INTEL_LRT11" can be used to build with compilers that
support threads intrinsically using the C++11 standard. When using
LRT mode, you might need to disable OpenMP affinity settings (e.g.
export KMP_AFFINITY=none). LAMMPS will generate a warning if the settings
need to be changed.
