Hi, Thank you for your answer! I am already able to use the OpenMP-style without RcppParallel, thanks to some examples given in the Rcpp community. I will have a look at the RViennaCL.
For my problem, the compiler is not important. I just mentioned the one I use as an example. However, I really have to use Windows.
