Dear R developpers,
I submitted a package involving some parallel functions.
I received this error message:
Error in .check_ncores(length(names)) : 30 simultaneous processes spawned
I read that CRAN only pass the test if 2 cores are used.
However, in my function, I use this command line:
parallel::makeCluster(parallel::detectCores() - 2)
I try to fit the power of each computer by allowing all the cores except 2
(to keep other software running).
My question is: What I have to do? Limiting the number of cores at 2 to
pass the CRAN requirements? Or let "detectCores() - 2" to allow for more
cores for multi-cores computer but add a restriction to pass the tests?
