hash-11 Garnet — performance on x86-64 (system x86_1)

Independent measurement following the structure of the NICCS x86 self-assessment guide, §3.5 (1)–(7). Not a submitter self-assessment.

3. Functional testing (KAT)

Each library was checked against the submitted KAT vectors (SHA-256 manifest hash-11/kat.sha256 in the harness) before timing.

Garnet_1024_DM4x4 harness-default MISMATCH [1] (not timed)

[1] No reference source: the submission ships a second 1024-bit KAT set (DM4x4, apparently a 512-bit-rate variant) whose only code is x86-64 assembly in the optimized tree; the harness label reuses the Garnet_1024 C sources, so its timing would duplicate Garnet_1024 (hash-11/pseudocode.md, discrepancy 3).

5. Resource consumption

Static memory is approximated by the library's loadable ELF segments; peak memory is the process high-water mark (VmHWM) including the benchmark driver and libc, so both are upper-bound proxies rather than isolated algorithm memory.
