## Choosing the SMT mode for computing nodes 

Many NPB applications benefit from SMT-4 mode. Therefore, from the general system management perspective, it can be unwise to restrict users to lower SMT values. The administrator should consider the following recommendations: 

GLYPH<SM590000> Run the system in SMT-4 mode by default. 

GLYPH<SM590000> Let the batch scheduler turn on SMT mode on a per job basis. 

GLYPH<SM590000> Use a processor core as a unit of hardware resource allocation. 3
