I believe the recommendation is not to use more than 2 cores.

Subject: [Bioc-devel] Maximum allowed cores on Bioconductor Build System?

Hi all,

I am wondering if there is a maximum allowed number of cores that can be
used when building a vignette on the Bioconductor Build System? I make use
of parallel computing in one of my vignettes, but if I don't use enough
cores, it takes too long to build the vignette and I get a timeout error.
Currently, I am just using BiocParallel::bpparam() to automatically choose
the parallel backend in the vignette.

Cheers,

Richard
