FluidX3D 3.7<\/a> – un pachet pentru dinamica fluidelor computa\u021bionale, care folose\u0219te metoda ecua\u021biilor Boltzmann pe gril\u0103 (LBM) \u0219i OpenCL. Proiectul este pozi\u021bionat ca un pachet CFD de \u00eenalt\u0103 performan\u021b\u0103 \u0219i eficient din punct de vedere al memoriei, capabil s\u0103 func\u021bioneze pe GPU-uri \u0219i CPU-uri de la diferi\u021bi produc\u0103tori prin intermediul OpenCL.<\/p>\n

Principala modificare din versiunea 3.7 a fost optimizarea nucleului pentru redarea izoferon\u021bei Q-criteriului (graphics_q()), utilizat pentru vizualizarea structurilor de vortex \u00een flux. \u00cen implementarea anterioar\u0103, nucleul \u00eenc\u0103rca din memoria video un model greu de 32 de viteze tridimensionale pentru fiecare celul\u0103 a re\u021belei. Acum, un grup de lucru de fire de dimensiune 8\u00d78\u00d78 \u00eencarc\u0103 un bloc de 11\u00d711\u00d711 viteze \u00een 16 KB de memorie local\u0103 de nivel 1, dup\u0103 care firele adiacente reutilizeaz\u0103 aceste date. Potrivit autorului, acest lucru reduce num\u0103rul de \u00eenc\u0103rc\u0103ri din VRAM cu aproximativ 12 ori \u2014 la 2,6 viteze pe celul\u0103 \u2014 \u0219i transfer\u0103 nucleul dintr-un mod limitat de l\u0103\u021bime de band\u0103 a memoriei \u00eentr-un mod limitat de calcule.<\/p>\n

C\u00e2\u0219tigul practic depinde de echipamentul specific. Pe GPU-uri noi cu un sistem de cache avansat, optimizarea manual\u0103 a memoriei locale poate oferi aproape niciun spor sau chiar poate reduce pu\u021bin frecven\u021ba cadrelor. Pe unele GPU-uri vechi, autorul a observat o accelerare de p\u00e2n\u0103 la dou\u0103 ori, ceea ce este deosebit de evident \u00een modul grafic interactiv FluidX3D. De exemplu, \u00een testele publicate, NVIDIA Titan Xp a accelerat de la 7 la 13 cadre\/s, Intel UHD 770 \u2014 de la 8 la 14 cadre\/s \u00eentr-unul dintre moduri, iar Intel Arc A750 \u2014 de la 22 la 26 cadre\/s.<\/p>\n

Pentru GPU-urile integrate mai vechi, s-a prev\u0103zut o revenire automat\u0103 la realizarea anterioar\u0103: unele dintre aceste dispozitive nu suport\u0103 grupuri de lucru de dimensiune 512 de fire sau au mai pu\u021bin de 16 KB de memorie local\u0103 L1. \u00cen aceste cazuri, FluidX3D va continua s\u0103 utilizeze vechea variant\u0103 a nucleului, p\u0103str\u00e2nd compatibilitatea.<\/p>\n

De asemenea, \u00een aceast\u0103 versiune au fost simplificate condi\u021biile pentru redarea VR, s-a dezactivat desf\u0103\u0219urarea ciclurilor \u00een rasterizare pentru a reduce \u201espaghetti\u201d-ul din ie\u0219irea \u00een assembler, a fost ad\u0103ugat\u0103 o micro-optimizare \u00een convert_triangle\/_interpolated(), iar \u00een adaptorul OpenCL a fost corectat\u0103 ie\u0219irea erorii \u00een cazul unui nume de nucleu gol \u0219i a dimensiunii grupului de lucru.<\/p>\n

<\/p>\n

FluidX3D include un renderer 3D interactiv integrat, care permite vizualizarea c\u00e2mpurilor de vitez\u0103, liniilor de curent, izo-superficielor criteriului Q \u0219i a sec\u021biunilor \u00een timp real, f\u0103r\u0103 a necesita exportul \u00een un instrument de post-procesare separat. FluidX3D<\/a> Proiectul mai include suport pentru suprafe\u021be libere, convec\u021bie termic\u0103, modelul de turbulen\u021b\u0103 Smagorinsky-Lilly, urm\u0103rirea particulelor, export VTK \u0219i func\u021bionarea pe mai multe GPU-uri.<\/p>\n

Este demn de men\u021bionat statutul de licen\u021b\u0103: codul surs\u0103 FluidX3D este deschis \u0219i disponibil pe GitHub, \u00eens\u0103 licen\u021ba proiectului<\/a> nu este liber\u0103 \u00een sensul strict al OSI\/FSF. Aceasta permite utilizarea pentru cercet\u0103ri publice, educa\u021bie \u0219i scopuri personale, dar interzice utilizarea comercial\u0103 \u0219i militar\u0103, precum \u0219i antrenarea modelelor AI pe baza codului surs\u0103.<\/p>\n
