Description
In this whitepaper we describe the effort we have made to measure performance of applications and synthetic benchmarks
with the use of different simultaneous multithreading (SMT) modes. This specific processor architecture feature is currently
available in many petascale HPC systems worldwide. Both IBM Power7 processors available in Power775 (IH) and IBM Power
A2 processors available in Blue Gene/Q are built upon 4-way simultaneous multithreaded cores. It should be also mentioned that
multithreading is predicted to be one of the leading features of future exascale systems available by the end of next decade [1].
