That's true for SPECcpu. SPEChpc, the MPI codes, require a cluster.
While the current version of these are not commonly run, there is a
new revision in the works which I hope will be more popular.

Note that all of the comparison numbers in my evil whitepapers were
run by other people, often system vendors, precisely because it is
important to get the best numbers to compare to. Maybe next time
Patrick will read something before he criticizes it? Better yet,
he could use my whitepaper as a suggestion of codes he could run,
because comparison results are available.
