CGH0S7	207efdbbb2	Fix C derivative ghost-buffer indexing across FD orders	2026-05-14 16:04:56 +08:00
CGH0S7	ce1fdc9686	Add C implementations of shell-patch derivative kernels (WithShell support) ... New files provide C equivalents of Fortran diff_new_sh.f90 and kodiss_sh.f90: - fderivs_sh_c.C: first derivatives in shell (rho, sigma, R) coords - fdderivs_sh_c.C: second derivatives in shell coords - fderivs_shc_c.C: shell first derivs + chain rule to Cartesian - fdderivs_shc_c.C: shell second derivs + chain rule to Cartesian - kodiss_sh_c.C: Kreiss-Oliger dissipation on shell patches Also add symmetry_stbd() C implementation and shell fh indexing to share_func.h. Controlled by USE_CXX_SHELL_KERNELS switch (default 0, experimental). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>	2026-05-14 11:26:50 +08:00
CGH0S7	02d71b27b9	Add full FD order support (2nd/4th/6th/8th) to C derivative kernels via ghost_width dispatch ... Wrap each C kernel in #if (ghost_width == N) blocks matching Fortran stencil coefficients from diff_new.f90, kodiss.f90, and lopsidediff.f90. Add fast-path indexing for ord=1,4,5 in share_func.h.

CGH0S7	16013081e0	Optimize symmetry_bd with stride-based fast paths	2026-03-01 15:50:56 +08:00
ianchb	284ab80baf	Remove OpenMP from C rewrite kernel ... The C rewrite introduced OpenMP parallelism. Remove all OpenMP.	2026-02-25 22:21:20 +08:00
wingrew	8a9c775705	Replace Fortran bssn_rhs with C implementation and add C helper kernels ... - Modify bssn_rhs_c.C to use existing project headers (macrodef.h, bssn_rhs.h) - Update makefile: remove bssn_rhs.o from F90FILES, add CFILES with OpenMP - Keep Fortran helper files (diff_new.f90, kodiss.f90, lopsidediff.f90) for other Fortran callers [copilot: fix compiling errors & a nan error] Co-authored-by: ianchb <i@4t.pw> Co-authored-by: copilot-swe-agent[bot] <198982749+copilot@users.noreply.github.com>	2026-02-25 22:21:19 +08:00
