If you want to distributed such binaries, I would suggest using the 'drat'
package to set up your own repo. I'm using it for beta versions of my
packages and I find it very useful and easy to use. The latest version of
'drat' also supports binaries.
Or, vote with your feet and switch to Linux ;-).
At least on linux, CRAN builds using openMP. I got a valgrind report once
[shame on me btw] showing that 9 (out of 10) threads were running examples.
So my best guess is that it will do the same for Windows since it also has
openMP support according to WRE[1]. I wouldn't know why not, except for

The way several packages have implemented OpenMP is to wrap it in pre-compiler
statements i.e.:
// Include openMP if the compiler supports it
#ifdef _OPENMP
#include
#endif
This way, all compilers can build the code and those that have OpenMP (even
modified versions of clang: https://clang-omp
Dirk, I pick one of the packages you suggested and asked my colleague to
test it on MacOS X. As you can see, it did not use more than 1 CPU. I
inspected the Makevars and found that it relied on
SHLIB_OPENMP_CXXFLAGS. This variable is set to -fopenmp on my laptop.
Does CRAN add -fopenmp to SHLIB

Interesting that you opt to ignore OpenMP support on the platform th
