pytc.solver.isdf_xtc_ccsd._measure_free_host_bytes()[source]¶

Measured available host RAM in bytes, capped by any cgroup limit.

psutil is imported lazily and treated as OPTIONAL: when it is absent the cgroup measurement alone answers, and when neither source exists the gate falls through safely (never admits on an unknown capacity).
