My recommendation: act on T1-A, T2-A (together as a cluster), T2-B, and T3-C. T2-C and T3-A/B are lower-leverage. Does that match your priorities? + 3. T1-B (no-T dispatch for host arrays): This is additive, but do you actually want users calling mismatch with plain AbstractArray arguments? Or is the intended path always through + CuArray (and the host-array method is a convenience that should stay explicit)? + 4. Release strategy: If T1-A is approved, would you like a final v0.3.x tag before the breaking change, or go straight to v0.4.0? diff --git a/.claude/design_review_report.txt b/.claude/design_review_report.txt new file mode 100644 index 0000000..25a738a --- /dev/null +++ b/.claude/design_review_report.txt @@ -0,0 +1,91 @@ + --- + Phase 4 — Design Review Report + + Likely Design Issues + + 1.

But cucartesianindex has no method for N ≥ 4 — any GPU kernel launch on 4D data would fail at runtime with an + obscure error. This is a latent type-system gap. + + --- + Design Questions + + Q1 — Is CuRCpair genuinely public? + CuRCpair is exported but is purely a GPU r2c buffer layout detail. No user of mismatch or mismatch! ever needs to touch it directly. Was it exported to allow power users to build + custom storage types, or is it an accidental export? If the latter, removing it from the export list would be a minor breaking change. + + Q2 — normalization as Symbol vs. dispatch type + Both high-level entry points take normalization=:intensity or :pixels, which routes to one of two completely different GPU kernels via a runtime if. An alternative design would use + singleton dispatch types (struct IntensityNorm end). The symbol approach matches the CPU counterpart in RegisterMismatchCommon — was keeping the API identical a deliberate choice? + Changing it would be breaking. + + Q3 — display=false keyword as perpetual compat shim (lines 115–117) + The constructors accept a display keyword that is explicitly ignored "for compatibility with the CPU version." Is this expected to remain indefinitely, or is there a plan to drop it + once users have migrated? It currently silently swallows the argument rather than warning. + + Q4 — NanCorrFFTs field names I0, I1, I2 + Inside fillfixed!, I1 holds the image, I2 holds the elementwise square, and I0 holds the NaN mask (theta). The index-based names are opaque. Was there a reason not to name them + theta, image, image_sq? (This is internal-only so it's not a breaking change.) + + Q5 — mismatch_apertures accepts kwargs... passed to CMStorage (lines 202–213) + The only recognized CMStorage keyword is display=false. Any other keyword silently disappears. Was this intended as a forward-compatibility shim, or should unknown keywords produce + an error? + + --- + Observations + + - calculate_threads, kernel_conv_components!, kernel_calcNumDenom_intensity!, and kernel_calcNumDenom_pixels! are all accessed via RM. in the test suite but have no docstrings and + no public annotation. If they are intended for advanced users building custom kernels, they warrant docstrings. If they are truly internal, the test-qualified access could be + replaced. + - CMStorage defines eltype and ndims but not size. A user who wants to know what aperture size a given storage handles must access cms.aperture_width directly. A size(cms) method + returning the aperture size would be natural. + - mismatch_apertures (line 192) calls CuArray{T}(sdata(fixed)) — sdata is a SharedArrays function for unwrapping shared arrays. This suggests fixed was once expected to commonly be + a SharedArray. Is this still a realistic input type, or a historical artifact? + - CuRCpair.rng is typed NTuple{N} with no element type constraint. In practice it always holds UnitRange{Int} elements, but the loose typing means the compiler can't specialize on + it. + - No show methods for CMStorage, CuRCpair, or NanCorrFFTs. At the REPL these fall back to the generic mutable struct display, which prints all fields including raw GPU array + pointers — not very readable. + + --- + Overall Character + + RegisterMismatchCuda is a tightly scoped, purpose-built GPU backend. Its design is largely coherent: the CMStorage / fillfixed! / mismatch! three-step pattern is clean, and the + allocating vs. in-place function pairs follow standard Julia idioms. The main tensions are (a) a module docstring that describes a richer API than the package actually owns, + creating a misleading first impression; (b) three active deprecations that should have been removed; and (c) fftfunc::Any on the hot path. If the author wanted to address the two + highest-leverage items, they would be: fix the module docstring (zero-cost, high user-facing impact) and remove the deprecations (the TODO: remove deprecations step in the + maintenance workflow will handle this). + + --- + Phase 5 — Values Clarification + + Before writing the plan, I'd like to understand your intent on a few points: + + 1. Scope and audience: Is this package purely a GPU backend consumed by RegisterMismatch users, or do you intend it to be usable standalone? And is CuRCpair's export intentional — + are there users who construct them directly? + 2. Central abstraction: CMStorage is clearly the centerpiece. Should it stay as-is (a flat mutable struct with all fields public), or would you prefer it to move toward a more + opaque type over time? + 3. Composability / Base interfaces: How much do you want to invest in show, size(cms), etc.? Or is the REPL experience for these types not a priority? + 4. Error model: The codebase mixes bare error() and ArgumentError.
