Omar SobhandClaude Fable 5.1	95ffde9591	rtx-cfd/rtx-fsi PERF-2 P3-iii: the MarchPlane — lane-table V-cycle kernels (ml_*), the batched apply over K lanes' own operators, the plane rendezvous inside the CG's preconditioner (lane thread-local, CG guard), set_plane_lane/plane_counters; the fsi2_overset_plane driver (K lane threads, one process); G-P0 unit tests: K distinct operators batched = solo apply bit for bit, uneven lanes served exactly ...

Omar Sobh	eba2f61ddf	rtx-cfd CUDA Poisson kernels: solve ∇²φ = f as documented (the updates subtracted the source with the wrong sign); the Jacobi test's stop is absolute on a source of size 2π²	2026-09-16 07:34:28 -05:00
Omar Sobh	0de750bad1	rtx-cfd legacy GPU: kernel outputs were device-buffer CLONES (every write lost) — the buffers are borrowed mutably now; the Poisson kernels keep boundary Dirichlet values; tests: the advection pulse marched 50 steps, the Jacobi budget 20k, the reduction reference in f64	2026-09-16 07:28:42 -05:00
Omar Sobh	f3f6ac21fb	rtx-cfd CUDA kernels: no host includes at all in the NVRTC sources; the float limits defined inline	2026-09-16 07:24:54 -05:00
Omar Sobh	64faa095a2	rtx-cfd CUDA kernels: no host headers in the NVRTC sources (cuda_runtime.h was never found: every legacy GPU test failed at manager creation)	2026-09-16 07:23:02 -05:00
Omar Sobh	1381b5b633	rtx-cfd legacy GPU tests: the current CudaKernelManager API (Arc-held manager, allocate-on-copy, copy_from_device returning the host vector), MatrixOpsKernel::tridiagonal_matvec added over the existing kernel, PoissonKernel::solve_jacobi_2d kept as the older name; CfdConfig literals take ..Default	2026-09-16 07:18:34 -05:00
Omar Sobh	3b7f8fb362	PERF-2 P3 bench: the coarsest level uses the CPU's red-black symmetric ordering (a nearly singular coarsest system settles on a smoother-dependent constant, which the prolongation doubled up every level: the 19 % disagreement)	2026-09-16 01:10:12 -05:00
Omar Sobh	956e9d38e2	rtx-cfd: the cuda feature builds again — the duplicate CudaKernelManager::stream removed, the legacy k-epsilon GPU model (broken since the initial commit) kept out of the build	2026-09-16 01:03:33 -05:00
Omar SobhandClaude Fable 5.1	0dc95a8de5	PERF-2 P3: the batched device V-cycle microbenchmark — mg_vcycle.cu (masked variable-coefficient five-point red-black half-sweeps, residual, CSR restriction in a fixed order, prolongation, coarsest sweeps; [K][n] layout, blockIdx.y = march), LevelExport/export_hierarchy and vcycle_f32_reference on the CPU side, and the ignored cuda-feature test that checks the K = 1 device V-cycle against the CPU f32 reference and times K = 1 / 8 / 16 per march ...
