Measured setup

Every option opens a recorded setup. Where the corpus recorded nothing at this page's other settings, the option names the fields it switches with it. Allocation and runtime detail stay in the technical record below.

No throughput measurements were recorded for this setup, so no rates are shown or plotted. The technical record below keeps the recorded outcome.

Notes
Single RTX3090 requested — placement unverified · EXL3 5.00bpw · MTP-1 · requested 262144-token fixed context allocation (startup OOM; actual allocation unknown). Persistent EXL native worker: 512 fresh prompt tokens and 256 generated tokens; one warmup then three measured repetitions. PP is fresh-prompt processing after the populated prefix; TG is aggregate decode across concurrent streams. Throughput means and sample standard deviations are recomputed from the retained raw repetitions. EXL native K8/V8 cache storage includes QSA side planes and recurrent state; this is not GGUF Q8_0. Physical GPU 1 (GPU-0a2bed40-39e4-e67f-5234-868704f9704b) was selected as the single device. No successful model placement was observed for this outcome-only source. Source configuration 500bpw-context-mtp-1-c1; model revision a35e75a73baee51da709329d19294245cbeeb5d8; source manifest SHA-256 f889b720ea21d731842579e93d41eb5e4ed995a63475a7e69874a2330b529192. This separate outcome-only configuration requested the original fixed 262144-token per-stream context allocation. Actual allocation and model residency were not established because startup failed.
