pub fn host_capacity() -> (u32, u32, u32)Expand description
Host capacity triple (cpus, llcs, max_cpus_per_llc) used to
filter gauntlet topology presets against what the host can actually
schedule. Both dispatch::list_tests_* (gauntlet variant filter)
and dispatch::list_verifier_cells_all (verifier sweep filter)
share this single source of truth so the two filters never drift.
Reads available_parallelism() for CPU count + HostTopology::from_sysfs()
for LLC layout; falls back to single-LLC + single-cpu-per-llc when
sysfs is unavailable.
