Whats the logic of default using hardware detection. Say My node has 8 actual core and 32 virtual cores. Its taking 26 as value of vcores available of this node on RM UI.

But total vcores displayed on RM's web page for the nodes are different than the default(8). Is there any other place to control this number ?
