Can multiple TBB DLL versions be installed side by side ?
For example, can we have <intel>_tbb_4.2 and <intel>_tbb_4.3 installed side by side on the same machine ?
What would be the impact on performance ?
Would both applications using separate code paths function without crashing or deadlocking ?
side by side install is one of supported enviroments.
Separated processes should not have bad impact except possible oversubscription in case they are running at the same time.
