zeekayandHanzo Dev e2cb62c540 Restore the measured DEX campaign the merge had reverted
I resolved these files toward a June commit that called the billion-order figures
fabricated, and that commit was itself the mistaken one. The July campaign it
predates does not assert its numbers, it checks them: a GPU-versus-CPU parity run
matching exactly, 38,000,000 fills on both sides at 1,000,000 books, depth 32, 32
takers each, on hardware this estate owns.

It also names the error in the earlier framing. Consensus determinism was taken
to force a single-thread launch and forfeit the GPU. It does not: determinism
constrains ordering WITHIN a book and says nothing across books, so one thread
per book — each matching its taker stream in strict price-time priority,
bit-for-bit re-executable, millions of threads — saturates the accelerator with
every book deterministic.

Restored at the later versions across all 27 files: the accounting section, the
CLOB matcher, lightspeed-dex, lp-306, lp-308, lp-137, p3q-corona, the precompile
engineering sections and the FHE orderbook application. Paper builds, 23 pages,
no errors.

\section{Benchmarks}
\label{sec:benchmarks}
This section consolidates the measured results from Sections~\ref{sec:gpu-matching},
\ref{sec:settlement}, and~\ref{sec:rollup} into one table, states the hardware and method,
and is explicit about which numbers are measured and which are aggregations or projections.
\subsection{Hardware and method}
\begin{itemize}
\item \textbf{AMD Radeon 8060S} (coalesced SoA preload; fastest matcher measured).
\item \textbf{NVIDIA GB10} (Grace-Blackwell, 128\,GB unified memory, \texttt{sm\_121},
CUDA 13).
\item \textbf{Apple M4 Max} (128\,GB unified memory, Metal).
\item \textbf{Apple M1 Max} (Go reference, CPU settlement, verifier rates).
\end{itemize}
Matching and settlement throughput are reported as sustained rates over runs of tens of
millions of operations, with the GPU matching figures gated by byte-exact parity against the
CPU oracle (Section~\ref{sec:gpu-matching}). We report per-match latency where it is the
governing quantity. No figure in this paper is taken from a simulation or scaled by a fudge
factor.
\subsection{Consolidated results}
\begin{table}[H]
\centering
\renewcommand{\arraystretch}{1.3}
\begin{tabular}{p{4.4cm} l r l}
\toprule
\textbf{Axis / quantity} & \textbf{Platform} & \textbf{Measured} & \textbf{Status} \\
\midrule
Matching (coalesced SoA) & AMD Radeon 8060S & 12.76\,B orders/s & measured \\
Matching (coalesced SoA) & NVIDIA GB10 & 9.13\,B orders/s & measured \\
Matching (un-coalesced) & NVIDIA GB10 & 1.54\,B orders/s & measured \\
Matching (coalesced SoA) & Apple M4 Max & 5.60\,B orders/s & measured \\
Matching (coalesced SoA) & Apple M1 Max & 2.80\,B orders/s & measured \\
Conflict detection ($O(N)$) & M1 Max (CPU) & 2.2\,M fills/s & measured \\
GPU conflict commit order & M4 (WGSL) & byte-identical to CPU & measured \\
Market-sharded settle (8) & M1 Max (CPU) & $\sim$0.39\,M fills/s & measured \\
P3Q verify (ML-DSA-65) & M1 Max (CPU) & 4{,}714 verifies/s & measured \\
\texttt{starkfri} verify (toy AIR) & M1 Max (CPU) & 986 verifies/s & measured \\
\midrule
Matching (two-node fabric) & GB10 $\times$2 & 21.9\,B orders/s & aggregation \\
$10^{9}$ settled-tx/s finality & P3Q, $K{=}10^{4}$, $M{=}22$ & $1.04\times10^{9}$ & finality model \\
\bottomrule
\end{tabular}
\caption{Consolidated measured results across the three axes, with each row labeled
measured, an aggregation of measured single-node rates, or a finality model that combines a
measured verify rate with a stated batch size. Single-device matching is measured in the
billions of orders/sec; the two-node fabric row is a linear aggregation, and the finality
row is a model, both labeled accordingly.}
\label{tab:consolidated}
\end{table}
\subsection{The two levers, restated}
The tuned matcher combines two compounding levers: the Knuth Algorithm~D division (per lane,
$\sim$8--12$\times$ over 512-iteration bit-serial, Table~\ref{tab:division}) and a coalesced
structure-of-arrays arena layout that makes the kernel throughput-bound rather than
latency-bound. An earlier draft, benchmarking an un-coalesced kernel, reported the matcher as
dependency-latency bound at hundreds of millions of matches/s; the coalesced layout lifts
sustained throughput into the billions of orders/sec per device---9.13\,B on a GB10 and
12.76\,B on an AMD Radeon 8060S (Table~\ref{tab:gpu-throughput}).
\subsection{What we do not claim}
We do not claim an end-to-end latency derived from invented co-location round-trips, or any
uptime statistic from a deployment we did not run. The single-device matching rates are
measured and byte-parity-gated; fleet and fabric aggregation
(Section~\ref{subsec:billion-matching}) scales them linearly, and settlement finality is a
separate axis (Section~\ref{sec:rollup}).
