I agree with Martin. I think it is worse for beginners to falsely believe their results are deterministic when they are not. This sounds like a problem that should be solved with documentation and maybe even examples of setting the RNG seed manually. I also worry about advanced users and pollution

Hello, Might it instead made possible to set an RNGseed value by specifying one to bpparam but still get the automated back-end selection, so that it could easily be set to a particular value in an R package? -- Dario Strbenac University of Sydney Camperdown

I'm not sure that this is a good idea? For instance R does not set the random number stream to be the same by default. Not sure what others might think... Martin On 11/26/21, 6:01 AM, "Bioc-devel on behalf of Dario Strbenac via Bioc-devel" wrote: Good day, I maintain an R package wh

Good day, I maintain an R package which makes use of functions such as bplapply which has bpparam() as the default. I have received feedback from a beginnre user that the results change when he knitted his R Markdown document a second time. This stems from the default constructor of bpparam() w
