[R-pkg-devel] Disable parallelism on installation time
Dear listeners,
I'm having a hard time trying to figure out the following NOTE:
|* checking whether package 'fio' can be installed... [202s/46s] NOTE
Installation took CPU time 4.4 times elapsed time |
Uwe asked if there's code running in parallel by default and, yes, there
was: my code uses rayon (general parallelism) and faer (linear algebra,
with rayon feature on) Rust crates. So I did a little refactor and added
a method to allow the user to specify max threads. Then I started every
example, tests, vignette and readme by limiting threads to 1 to avoid
parallelism.
Nonetheless, I still get the NOTE. Finally, out of despair, I've deleted
vignettes, tests, code on readme and enclosed all examples
with|\dontrun{}|but that didn't work either.
So my question is, besides examples, tests, vignettes and readme,*what
parts of code runs during installation of a R package? Is parallelism
the only trigger for that NOTE or could it be something else?*
Source code is here and there's
also a SO post with my failed attempts
in detail.

This is about `cargo build` compiling in parallel, not your package code computing in parallel. Giving the -j 2 flag to cargo should solve the problem: https://github.com/R-ArcGIS/arcgisgeocode/blob/8fbd93c3607363a9fef2d445711de647e5127566/src/Makevars#L5 -- Best regards, Ivan __ R-package-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-package-devel

To add to this, I would like to point out that extendr actually has a guide on how to make an R package with Rust code CRAN compliance. https://github.com/extendr/rextendr/blob/main/vignettes/articles/cran-compliance.Rmd On Wed, Jul 17, 2024 at 10:21 AM Ivan Krylov via R-package-devel wrote: > > В Tue, 16 Jul 2024 21:18:17 -0300 > Alberson Miranda пишет: > > > besides examples, tests, vignettes and readme, what parts of code > > runs during installation of a R package > > Neither.
