Fr0zkaandClaude Opus 5.5 4b1108bf86 wip(assembler): round L7 -- shared column cache across workers: whole view 16-19% faster, world unchanged ...

SharedColumnCache.h: a world-owned, bounded 4-way second-tier cache of exact column values
(heightfield and floating islands), keyed by recipe/plan identity plus content hash, XY and island
id. Lock-free seqlock reads; set-local spin lock on misses. The FLazy thread-local tier stays
first. 83.6% of repeated column work was cross-worker; formula evaluations -60.9%.
W12 L1 view: Luna 2.165 -> 1.754 s; reviewer interleaved 2.059 -> 1.722 s. 8 m crossing new tiles
82 -> 52 ms. +66 MiB peak RSS. All hashes (whole view, per-LOD, exact queries, islands seed 0)
identical at W1/W8/W12, Clang off and GCC default. MSVC/UBT not compiled here.

Linux1

wip(assembler): round L1 -- Linux baseline on abyss: Linux world identical to Windows

2026-10-19 18:18:34 +02:00

Linux2

wip(assembler): round L2 -- the cross-platform hash check can fail; FP contraction changes the world

2026-10-19 18:18:34 +02:00

Linux3

wip(assembler): round L3 -- Core forces FP contraction off and refuses to generate if it can't

2026-10-19 18:51:07 +02:00

Linux4

wip(assembler): round L4 -- lazy per-thread caches: 17.3 MiB -> 43 KiB per thread, view 7% faster

2026-10-19 19:16:14 +02:00

Linux5

wip(assembler): rounds L5+L6 -- Linux far-terrain captures and screen-space gate (world unchanged)

2026-10-19 21:10:08 +02:00

Linux6

wip(assembler): rounds L5+L6 -- Linux far-terrain captures and screen-space gate (world unchanged)

2026-10-19 21:10:08 +02:00

Linux7

wip(assembler): round L7 -- shared column cache across workers: whole view 16-19% faster, world unchanged

Round1

wip(assembler): M3 round 2 -- islands get real mass: deep crust, separate tapered roots, arched spans

2026-10-10 12:24:35 +02:00

Round2

wip(assembler): M3 round 2 -- islands get real mass: deep crust, separate tapered roots, arched spans

2026-10-10 12:24:35 +02:00

Round3

wip(assembler): M3 round 3 -- separated islands + Unreal island route (owner build 18:46)

2026-10-10 20:53:03 +02:00

Round4

wip(assembler): M3 round 4 -- plans built inside Unreal from the owner's strates; no import needed

2026-10-10 22:48:46 +02:00

Round5

wip(assembler): round S1 -- one Core voxel-size source; per-tile feature lists (islands)

2026-10-18 18:48:38 +02:00

Round6

wip(assembler): round S2 (Sol) -- shared per-tile feature queries for every Core family; island placement 30x faster

2026-10-18 19:50:45 +02:00

Round7

wip(assembler): round S3 -- far ground from the native heightfield; LOD7/8 tiles 36-66% cheaper

2026-10-18 21:29:52 +02:00

Round8

wip(assembler): round S4 -- continuous far ceiling at the strate's upper boundary

2026-10-19 00:41:13 +02:00

Round9

wip(assembler): round S5 -- streaming gates + trace; coarse-first order kept opt-in (no win)

2026-10-19 04:42:41 +02:00

Round10

wip(assembler): round S6 -- in-game cold view counted; workers mostly idle, apply cap not the floor

2026-10-19 06:46:54 +02:00

Round11

wip(assembler): round S7 -- workers kept busy: in-game cold full view 17.5 s -> 7.8 s

2026-10-19 08:10:10 +02:00

Round12

wip(assembler): round S8 -- region rebuilds no longer stall admission; result backlog capped

2026-10-19 09:43:03 +02:00

Round13

wip(assembler): round S9 -- collision look-ahead: ground ring ready on arrival up to 40 m/s and 50 m/s falls

2026-10-19 10:56:54 +02:00

Round14

wip(assembler): round S10 -- LOD8 horizon sampled at MC spacing: LOD8 worker time 18.8 s -> 4.3 s

2026-10-19 12:23:18 +02:00

Round15

wip(assembler): round S11 -- bounded spawn apply budget: in-game full set 7.1 s -> 6.0 s

2026-10-19 13:03:44 +02:00

Round16

wip(assembler): round S12 -- short ready queue keeps workers fed between ticks: full set 6.0 s -> 4.9 s

2026-10-19 14:29:38 +02:00

Round17

wip(assembler): round S13 -- tile cost counted per LOD (diagnostics only, no output change)

2026-10-19 15:40:25 +02:00

Round18

wip(assembler): round S14 -- 4-way column cache + memoized MC gradients (output unchanged)
