plan: the prover-floor agent's sweep 3 rows (the patched server proves the v1 shard at 10.3 GB on the 12 GB profile, 12.9 GB at 2^27; the 12 and 16 GB rows move from nothing to proves alone, the pairs pending)

|---|---|---|---|
| 32 GB (RTX 5090) | the prototype shard, 28.3 GB, 10.8 s; the v1 shard 20.4 GB, 4.3 s | the prototype shard 30.1 GB, 33 s; the v1 shard 22.2 GB, 13.2 s | on, mine and prove, today |
| 24 GB (RTX 4090, 3090) | the v1 shard 20.4 GB; the prototype shard does NOT fit (28.3 GB) | the v1 shard 22.2 GB measured on the 5090's allocation (2.3 GB spare on a 24 GB card; approximate for the card itself) | on, mine and prove, with the line "until the devnet's fee switch its shards are the prototype size, which needs 32 GB, so this card proves from the switch on" |
| 16 GB (RTX 5080, 4080) | an empty shard only (13.9 GB) | nothing (15.7 GB for an empty shard, no room for the display) | off, with the line |
| 12 GB (RTX 3060, 4070) | nothing: the floor is 13.9 GB, and the shipped server refuses the card outright | nothing | off; the project lead's "make sure we can prove on 12 GB cards" is OPEN and in work: the prover-floor agent (branch prover-floor, 5 October night) read SP1 v6.8.1's GPU server source (`sp1-gpu/crates/prover_components/src/builder.rs` lines 35 to 39): it reads the card's memory, adds 4 and panics under 24 ("Unsupported GPU memory ... must be at least 24GB"), and builds its core (ELEMENT_THRESHOLD 2^28 + 2^27 elements + 2^21), recursion (2^27), shrink (2^25) and wrap (85 M element) provers at Setup whatever the mode, which is the 13.9 GB floor; no knob reaches them, so the fix is a server rebuilt from source on PC 2 (WSL2, nvcc 12.8, CUDA_ARCHS=120) with those sizes cut, measured on the same fixtures and recipe as the curve above (D2 carries the curve) |
| 16 GB (RTX 5080, 4080) | the shipped server: an empty shard only (13.9 GB); the patched server v3 b37defef at threshold 2^27: the v1 shard 12,915 MiB and 4.3 s, the prototype shard 13,459 MiB and 16.8 s (measured by the prover-floor agent on the 5090's allocation, job `floor-sweep-3`, 00:13 to 00:17Z 6 October; 2^27 + 2^26 gives 16,115 MiB, over the card) | the shipped server: nothing (15.7 GB for an empty shard); the patched server: about 14.7 GB at 2^27 beside the miner (approximate: the measured 1.8 GB the miner adds; the pair is the agent's sweep 4) | off on the shipped server, with the line; on once the patched server ships (the packaging row below) and the pair is measured |
| 12 GB (RTX 3060, 4070) | the shipped server: nothing (the floor is 13.9 GB, and the server refuses the card outright); the patched server v3 b37defef at threshold 2^26 (`SP1_GPU_ELEMENT_THRESHOLD=67108864`, the 12 GB profile): **the v1 shard 10,291 MiB and 5.7 s, an empty shard 9,971 MiB and 3.3 s**, the card's 2,089 MiB idle inside the peak and the server's own working set about 8.2 GB (6,535 MiB after Setup), so a 12 GB card proves alone with about 3 GB over it (measured by the prover-floor agent on the 5090's allocation, `floor-sweep-3`; the on-order RTX 3060 run is pending) | the pair (the miner's 1.7 to 1.8 GB and 3x beside it) is the agent's sweep 4; under 9.0 GB mine-and-prove is not yet shown | off on the shipped server; "proves alone" on the patched one once it ships (the packaging row below), mine-and-prove after the pair. the project lead's "make sure we can prove on 12 GB cards" is answered on the 5090's allocation and OPEN on the card itself: the prover-floor agent (branch prover-floor, 5 October night) read SP1 v6.8.1's GPU server source (`sp1-gpu/crates/prover_components/src/builder.rs` lines 35 to 39): it reads the card's memory, adds 4 and panics under 24 ("Unsupported GPU memory ... must be at least 24GB"), and builds its core (ELEMENT_THRESHOLD 2^28 + 2^27 elements + 2^21), recursion (2^27), shrink (2^25) and wrap (85 M element) provers at Setup whatever the mode, which is the 13.9 GB floor; no knob reaches them, so the fix is a server rebuilt from source on PC 2 (WSL2, nvcc 12.8, CUDA_ARCHS=120) with those sizes cut, measured on the same fixtures and recipe as the curve above (D2 carries the curve) |
| under 12 GB | nothing | nothing | off, mine only |
| AMD-only and Apple machines | nothing on the GPU: no zkVM proves on an AMD GPU today (`docs/analysis/amd-proving.md`, branch amd-prove); the CPU prover is about 5 minutes a shard at a 30 GB RSS whatever the shard size (PC 1, bench-log "the SP1 CPU prover on PC 1") | | off, "mines and does not prove"; the only non-NVIDIA path with a shipped backend is RISC Zero's Metal prover behind the `ProofSystem` seam (a second guest and pinned id, a verifier for both formats, no shared aggregation): an open item, not 0.3.11 |
