Description
An ARM cluster, CEPH, ROOT and the energy balance
The total cost of ownershipt (TCO) of todays computer centres are
increasingly driven the power consumption of computing equipment. The
question arises if Intel based CPUs are still the best choice for analysis
tasks. Furthermore, data-driven computing models are emerging.
This contribution compares performance, TCO, power and energy consumption
of an ARM based CEPH cluster with off the shelf computers and an average
GridKa compute node. The ARM cluster was constructed from 16 CubieBoards
that comprise a dual Core ARM-A7 CPU at 1GHz as well as a SATA controller.
As analysis use case of this comparison we chose a
simple high-energy di-muon events simulated for LHC.
The goal is to assess which configuration is better suited for future
analysis hardware.
