Intel ayaa siidaayay OSPray 2.0 oo qaybiyay mishiinka raadraaca raajo

Intel soo bandhigay siideynta muhiimka ah ee matoorka wax qabad ee 3D la miisaami karo OSPray 2.0, loogu talagalay waaqiciga, tayada sare leh ee raajo raadraaca ku habboon codsiyada isdhexgalka. Matoorka waxaa loo soo saarayaa qayb ka mid ah mashruuc weyn Qaab-dhismeedka Intel, looga dan leeyahay in lagu horumariyo agabka muuqaalka software ee xisaabinta sayniska SDVis (Software Defined Visualization), oo ay ku jirto maktabad baafinta raajo Embree, hab sawir-qaadis ah oo sawir leh GLuRay, maktabad loogu talagalay in laga saaro buuqa sawirada oidn (Sawirka Furan ee Denoise) iyo nidaamka rasterization software FurSWR. Koodhku wuxuu ku qoran yahay C++ iyo la daabacay shatiga ku haysta Apache 2.0.

OSPRay waxaa loogu talagalay in lagu isticmaalo codsiyada isdhexgalka ee samaynta muuqaalada duullimaadka. Si loo ekaysiiyo hab-dhaqanka iftiinka, hab ayaa la isticmaalaa dariiq raadin. Aragtida mugga iyo diyaaradda waa la taageerayaa, sawir ahaan iftiimin caalami ah iyada oo la tixgelinayo sifooyinka muuqaalka ah ee alaabta, saameynta sare ee hooska (hadhka, daahfurnaanta iyo hadhka "Soocid ambient ah").

OSPray waxa ay isticmaashaa oo kaliya awoodaha CPU-ga, iyada oo aan lagu xidhin GPU-da, taas oo u ogolaanaysa maktabadda in loo isticmaalo qalabyo kala duwan, laga bilaabo goobaha shaqada ilaa noodhka xisaabinta. Si loo hubiyo waxqabadka saxda ah, isku-dhufashada iyo vectorization ee ku saleysan tilmaamaha SIMD, sida Intel SSE4, AVX, AVX2, iyo AVX-512, ayaa si firfircoon loo isticmaalaa (OSPRay waxay u baahan tahay taageerada SSE4.1 ugu yaraan).

Bandhiga waxaa loo qaybin karaa dhowr nood (oo ay taageerto MPI), kuwaas oo, tusaale ahaan, kuu ogolaanaya inaad isticmaasho OSPRay si aad u habayso soo bandhigida sawirada oo leh qaraar aad u sarreeya gidaarada video, hal sawir kaas oo ay ka samaysan yihiin qaybo LCD ah oo kala duwan. Tusaale ahaan, hawlgalka OSPray waxaa lagu muujiyay shaashad isku dhafan Xariga, oo ka kooban 80 30-inji kormeerayaal (wadarta xallinta 40960×8000 ama 328 megapixels) oo ay u adeegaan koox ka kooban 40 server oo leh 6-core CPUs oo ku salaysan Intel Sandy Bridge microarchitecture.

Isbeddelka muhiimka ah ee nambarka nooca waxaa sabab u ah dib u habeyn weyn oo API ah, oo ay ku jiraan hordhaca isbeddelada jebiya iswaafajinta (si loo fududeeyo u gudubka API-ga cusub, maktabad lakab ayaa la soo jeediyay taas oo sahlaysa socdaalka), iyo bixinta noocyo joomatari cusub. Taageero lagu daray VKL Furan (Maktabadda Kernel Volume Furan) ee samaynta mugga. Isku xirnaanta waa la fuliyay module si loo yareeyo buuqa sawirka. Maktabadda ospcommon iyo cutubka taageerada MPI waxa la dhigay meelo kayd ah.
