Are you using CMake, Ninja, or Cargo? Does it default to using as many parallel processes as feasible? Most build systems nowadays accept the -j flag to control that. Make sure to give it the flag that limits it to two processes (most likely -j 2) when running on CRAN: http://contributor.r-project.org/cran-cookbook/code_issues.html#using-more-than-2-cores The above advice is very general and may completely miss the mark. If you provide the links to the latest CRAN pre-test logs and the package source code, someone will be able to give more precise advice. -- Best regards, Ivan __ R-package-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-package-devel
[R-pkg-devel] CRAN Debian error installation time
Dear All,
I am writing to you because I am getting this NOTE from the CRAN Debian
machine that is not allowing CRAN acceptance: "Installation took CPU time
2.9 times elapsed time". Uwe Ligges told me that this means that I am using
more than 2 cores, but I must not use more than 2 by default.
In order to overcome this issue, I have included an R script inside the R
folder named with my package name and this content:
.onLoad <- function(libname, pkgname) {
if (Sys.getenv("OMP_THREAD_LIMIT") == "") {
Sys.setenv(OMP_THREAD_LIMIT = "2")
}
}
In addition, I have included explicitly the parameter numThreads
setThreadOptions(numThreads = 1) in the function where I use the
setThreadOptions from the RcppParallel package. However, the CRAN NOTE
persists.
Do you know how to fix that?
Many thanks in advance.
Kind regards,
Guillermo

May have been mentioned up-thread, but perhaps you also need to
control BLAS parallelization?
https://stackoverflow.com/questions/72669579/c-how-to-set-environment-variable-so-openblas-runs-multithreaded
(also see the RhpcBLASctl package; hopefully you don't need it, but
worth knowing about)
