Description
The recent generation of Intel XEON CPUs comes with support for
symmetric multi processing, formally known as hyperthreading. In
addition, a new CPU feature has been added, the Intel Turbo mode.
The influence of these features on the system performance has been
tested using the HEPSPEC06 benchmark suite, with enhanced statistics,
and a study of the scaling behaviour has been done.
The results of these tests are presented, and consequences for
certain applications as well as for procurement procedures themselves
are discussed.
