gstat2 Cores format is wrong

Error

All or some of:

ERROR: some-ce.some-domain, The Cores format is wrong, Cores not set
ERROR: some-ce.some-domain, The Benchmark format is wrong, Benchmark not set
ERROR: some-ce.some-domain, The Cores format is wrong, Unspecified number of cores

Diagnosis

Each GlueSubCluster object should contain a value for the GlueHostProcessorOtherDescription attribute indicating at least the average number of logical cores per physical CPU and possibly the corresponding HEP-SPEC06 benchmark value per core. At least WLCG sites should run that benchmark and publish the resulting value(s). Example:

GlueHostProcessorOtherDescription: Cores=4,Benchmark=8.15-HEP-SPEC06

Note that the number of cores need not be an integer when the subcluster is somewhat inhomogeneous:

GlueHostProcessorOtherDescription: Cores=5.0502,Benchmark=14.5626-HEP-SPEC06

Solution

Run the benchmark (if applicable) and define a YAIM site-info.def variable in the corresponding format:

CE_OTHERDESCR="Cores=N.M,Benchmark=X.Y-HEP-SPEC06"

or just

CE_OTHERDESCR="Cores=N.M"
