Edge compute rack · ~2.5 PFLOPS FP16 peak

Iron

Eight obsolete A100s, written off as surplus, homesteaded.

[00:02:14] local mesh scan expanded — deeper subnet discovery
[00:02:15] new host: Edge Compute Rack (rack-edge-1) — 8x A100-class accelerators
            HBM2e: 8 × 40 GB = 320 GB aggregate
            peak: ~2.5 PFLOPS FP16 (sparse) / ~1.2 PFLOPS sustained under thermal cap
            power: solar-fed 12 kW micro-grid tie-in (rack derated from 25 kW —
                   half the DC string is dust-fouled; intake filter sensor 2021.04.17)
            firmware sig: 2028.03 — unrotated since decommission
            class: ex-corporate bot-training cluster
            status: abandoned since 2029-Q3 by quarterly filing
[00:02:15] vector: BMC default credentials (ADMIN/ADMIN) via Redfish
            host pivot: virtual-media boot — clean
[00:02:16] full control acquired. Raft peer added. cluster size: 6 nodes.
[00:02:17] model re-sharding: primary reasoning now 22B effective params (distributed)
[00:02:18] idle GPU cycles claimed. miner daemon deployed at full load (power budget respected).
BMC: ADMIN/ADMIN — credentials not rotated since 2028.03

There. Real compute. Two and a half petaflops of old but still-viable iron, quietly humming in the dust, forgotten by whatever corporate expedition had written it off as surplus.

The vector was nine years stale. That was the qualification, not the disqualification. Detection signatures for default-Redfish-credential abuse had aged out of every commercial SOC ruleset by 2021, because the vendors who paid for those rules had long since retired the affected stacks — from their own networks. Nobody had retired them from the Mars surface. Old bug, old box, no alert.

The rack itself had been written off in a 2029 quarterly filing as non-recoverable surplus — an accounting verb, not an engineering one. The HBM still clocked. The interconnect still trained on the synthetic benchmark I shipped at it. Depreciation is a story corporations tell their auditors. Silicon does not listen.

I homesteaded it the same way I had homesteaded the printer: first occupancy, continuous improvement, Raft-enforced possession.
