I'm sure (corrections welcome!) that it's not an error to use a Fortran variable before an OpenMP parallel block that also uses it for a reduction operation. One more OpenMP-related problem that may still bite you is having to limit the number of threads. Since there's currently no centralised way of regulating all kinds of parallelism used in a given R session [1], you will have to use no more than two threads by default [2], although you are always welcome to start more if the user explicitly passes such an option to one of your functions. (I'm trying to help with this [3], but it may take a long while to implement properly and even longer to ensure that this is the right solution from both technical and social viewpoints.) -- Best regards, Ivan [1] https://stat.ethz.ch/pipermail/r-package-devel/2023q3/009513.html [2] https://cran.r-project.org/web/packages/policies.html [3] https://stat.ethz.ch/pipermail/r-package-devel/2023q4/009769.html ______________________________________________ R-package-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-package-devel
