This page explains how APEL accounting is done at the RAL Tier-1 in order to ensure that CPU benchmarks are taken into account properly.
The HTCondor configuration on the worker nodes includes the following:
RalScaling = 2.14 STARTD_ATTRS = $(STARTD_ATTRS) RalScaling
Here RalScaling is a scaling factor used to normalize the CPU benchmarks. Quattor is configured to do this automatically.
The HTCondor configuration on the ARC CEs contains
# CPU benchmark scaling factor MachineRalScaling = "$$([ifThenElse(isUndefined(RalScaling), 1.00, RalScaling)])" SUBMIT_EXPRS = $(SUBMIT_EXPRS) MachineRalScaling
We include the following line in the [grid-manager] section of /etc/arc.conf:
authplugin="FINISHING timeout=60,onfailure=pass,onsuccess=pass /usr/local/bin/scaling_factors_plugin.py %S %C %I"
where scaling_factors_plugin.py is available here: https://gist.github.com/alahiff/3a427620e73b42d9282d#file-scaling_factors_plugin-py.
