Requires an Intel compiler as well as the Intel TBB and MKL libraries. In Long-range thread mode (LRT) a modified verlet style is used, that
operates the Kspace calculation in a separate thread concurrently to
other calculations. This has to be enabled in the "package intel"_package.html
command at runtime. With the setting "threads" it used the pthreads
library, while c++11 will use the built-in thread support of C++11
compilers. The option "none" skips compilation of this feature. The
default is to use "threads" if pthreads is available and otherwise "none".
Best performance is achieved with Intel hardware, Intel compilers, as well as
the Intel TBB and MKL libraries. However, the code also compiles, links, and
runs with other compilers and without TBB and MKL.
