"Clean minimalist technical diagram on a dark blackboard background, illustrating floating-point reduction-order nondeterminism in GPU kernels. Left panel: a single narrow binary summation tree labeled 'batch=1', clean white chalk lines converging to one glowing dot, deterministic. Right panel: a wide parallel reduction tree labeled 'batch=8', branches reordered and colliding, two output nodes glowing slightly different shades of orange to show divergence. Thin blue and yellow chalk accent lines, small annotation arrows, infographic vector-illustration style, high contrast, no readable text/logos, engineering-whiteboard aesthetic" Recipe: Flux 2 dev + Turbo LoRA · 1536x864 · seed 3337244318830348490 · 8 steps — local on the 5090, $0.

深色黑板背景上的简洁极简技术示意图，演示 GPU 内核中浮点归约顺序的非确定性。左侧面板：一棵细窄的二叉求和树，标注 'batch=1'，干净的白色粉笔线条汇聚到一个发光的点，结果是确定性的。右侧面板：一棵宽阔的并行归约树，标注 'batch=8'，分支被重排并发生冲突，两个输出节点发出略有不同的橙色光芒以显示发散。细而克制的蓝色与黄色粉笔辅助线、小巧的注释箭头、信息图风格的矢量插画质感、高对比度，不出现任何可读的文字或 logo，工程白板的视觉美学
