Description
Starting with ROOT v6_10_00a onward, ROOT is built with TBB and implicit multi-threading support. In order to activate implicit multi-threading at runtime, gROOT->EnableImplicitMT() must be called, although in order to avoid conflict with our own initialization of TBB the latter must come before the former.
I propose we provide an optional parameter, say, services.scheduler.enableROOTImplicitMT (defaulting to false). However, before calling gROOT->EnableImplicitMT() we may wish to have braces in addition to belt by checking for the presence of the word, "imt" in the result of gROOT->GetConfigFeatures(), since an attempt to activate IMT without support present will most likely result in an exception.
