Not according to the spec you don't - you publish 16. The PDF linked
earlier explicitly declaims any advertising of job slots:
"LogicalCPUs counts the number of computing units seen by the OS on
the WNs. Sites typically configure one job slot per logical CPU, but
some sites allow more than this (e.g. five jobs per four cores) to
allow for the fact that jobs spend some time waiting for i/o. The
1.3 GLUE schema does not allow such an over allocation to be published
explicitly."
