Description
With the proliferation of multi-core x86 processors, it is reasonable to
ask whether the supporting infrastructure of the system (memory
bandwidth, IO bandwidth etc) can handle as many jobs as there are cores.
Furthermore, are traditional benchmarks like SpecINT and SpecFloat
adequate for assessing multi-core systems in real computing situations.
In this paper we present the results of simulation and full
reconstruction jobs with the ATLAS software Athena on both Intel and AMD
multi-core systems. The aim of this paper is to examine whether there is
a performance penalty associated with multi-core systems. And if there
is, the threshold (number of jobs / cores) at which that penalty is
first observed.
