Provide information on likely setcluster # #20

Closed bquistorff closed 7 years ago

It would be nice if we could give a guess to the user as to what to number to put for -parallel setclusters-. That way if they type an empty -parallel setclusters- (with no number) or they try to use parallel without setting the cluster we can suggest a number and even print a command that they could click on. We could query the c(processors_mach) and have our guess be something like 75% of clusters until we max out at 8 (and if there are 2-3 processors then we guess 2).

Isn't that macro only available for MP? I've thought about this, perhaps we can use this instead

, This for Unix

For Unix, you are correct, but my Stata 13 SE on Windows does report it. So, some platform dependent solution would be needed.

I think this is covered by setclusters default now.
