Bido na ngwa Intel® DPC++ ndakọrịta

Ngwá ọrụ ndakọrịta nke Intel® DPC++ na-enyere aka na mbugharị nke mmemme onye nrụpụta nke edere na CUDA* gaa na mmemme edere na Data Parallel C++ (DPC++), nke dabere na C++ ọgbara ọhụrụ ma tinye ụkpụrụ ụlọ ọrụ mbugharị dị ka SYCL*.

Gaa na ntuziaka onye nrụpụta ngwa ndakọrịta nke Intel® DPC++ na ntụaka maka ozi ndị ọzọ gbasara ngwa ahụ.
Gaa na ndetu mwepụta maka okwu ama ama yana ozi kachasị ọhụrụ.

IHE Iji Intel® DPC++ Ngwa ndakọrịta ga-ebute ọrụ na-agaghị akwaga kpamkpam. Ọrụ mgbakwunye, dị ka e depụtara site na mmepụta nke Intel® DPC++ Ngwa ndakọrịta, achọrọ iji mechaa mbugharị ahụ.

Tupu Ị Malite

Ngwá ọrụ ndakọrịta nke Intel® DPC++ gụnyere na Intel® oneAPI Base Toolkit. Ọ bụrụ na ị tinyebeghị Intel® oneAPI Base Toolkit, soro ntuziaka dị na ntuziaka nwụnye.

Ụfọdụ nkụnye eji isi mee CUDA files (kpọmkwem na ọrụ gị) nwere ike ịdị mkpa ịnweta Intel® DPC++
Ngwa ndakọrịta. Ngwá ọrụ ndakọrịta nke Intel® DPC++ na-achọ nkụnye eji isi mee CUDA ndị a files na ebe ndabara:

/usr/local/cuda/gụnyere
/usr/local/cuda-xy/gụnye, ebe xy bụ otu n'ime ụkpụrụ ndị a: 8.0, 9.x, 10.x, na 11.0–11.6.

Ị nwere ike zoo aka na ọnọdụ omenala site n'ịtụ aka na -cuda-include-path= nhọrọ na Intel® DPC++ Ngwa ndakọrịta iwu ahịrị.

IHE CUDA gụnyere ụzọ ekwesịghị ịbụ otu, ma ọ bụ ụzọ ụmụaka nke, ndekọ ebe koodu isi iyi nke kwesịrị ịkwaga dị.

Ugbu a, Intel® DPC++ Ngwa ndakọrịta na-akwado mbugharị nke mmemme etinyere na ụdị CUDA 8.0, 9.x, 10.x, na 11.0–11.6. Enwere ike ịgbatị ndepụta asụsụ na ụdị akwadoro n'ọdịnihu.

Iji guzobe gburugburu ngwa ndakọrịta Intel® DPC++, mee ihe ndị a:

Okwu mkpesa n'ozuzu sitere na shei sistemu arụ ọrụ bụ:

IHE c2s bụ utu aha nye iwu dpct ma enwere ike iji ya n'ọnọdụ ya.

Ozi ojiji arụnyere n'ime ya

Ịdọ aka ná ntị ewepụtara

Ngwá ọrụ ndakọrịta nke Intel® DPC++ na-achọpụta ebe dị na koodu ahụ nwere ike ịchọ nlebara anya gị n'oge njem nke files iji mee ka koodu SYCL kwekọọ ma ọ bụ dozie.
A na-etinye nkọwa n'ime ebe ewepụtara files wee gosipụta dị ka ịdọ aka ná ntị na mmepụta. Maka exampLe:

Nyefee a Mfe ule oru ngo

Ngwá ọrụ ndakọrịta nke Intel® DPC++ na-abịa na ọtụtụ sample project ka ị nwee ike inyocha ngwá ọrụ ahụ wee mara onwe gị ka ọ si arụ ọrụ:

Sampna Project	Nkọwa
Vector Tinye DPCT vector_add.cu	Vector Tinye DPCT sample na-egosi otu esi esi na CUDA kwaga SYCL dị mfe. Vector Add na-enye ụzọ dị mfe iji nyochaa na edobere gburugburu mmepe gị nke ọma iji jiri Intel® DPC++ Compatibility Tool.
Nhọrọ nchekwa DPCT isi.cu bar/util.cu bar/util.h	Nhọrọ nchekwa DPCT sample na-egosi otu esi akwaga ọrụ dị mgbagwoju anya yana iji nhọrọ.
Rodinia NW DPCT agịga.cu agịga.h needle_kernel.cu	Ndị Rodinia NW DPCT sample na-egosi otu esi esi na CUDA gaa na SYCL iji Intel® DPC++ Compatibility Tool.

Review README file nyere na nke ọ bụla sample maka ozi zuru oke gbasara ebumnuche na ojiji nke sample oru ngo.

Iji nweta samples

jiri oneapi-cli utility họrọ dị kaample site na ngalaba Intel® DPC++ Ngwa ndakọrịta, ma ọ bụ
budata samples si GitHub*.

Maka ozi ndị ọzọ gbasara otu esi ebudata na ịnweta sampma, gaa na Intel® oneAPI Base Toolkit Bido ntuziaka:

Gbalịa otu Sampna Project

Soro usoro ndị a ka ịkwaga Vector Tinye DPCT samporu ngo site na iji Intel® DPC++ Ngwa ndakọrịta:

Budata vector_add.cu sample.
Gbaa ngwa ndakọrịta Intel® DPC++ site na sampna mgbọrọgwụ ndekọ:

dpct -in-root = . src/vector_add.cu

Ihe vector_add.dp.cpp file kwesịrị ịpụta na ndekọ dpct_output. Nke file bụ ugbu a SYCLsource file.
Gaa na isi iyi SYCL ọhụrụ file:

cd dpct_mmepụta

Nyochaa koodu iyi ewepụtara wee dozie koodu ọ bụla nke ngwa ndakọrịta Intel® DPC++ enweghị ike ịkwaga. (koodu ejiri na example dị mfe, yabụ mgbanwe ntuziaka nwere ike ọ gaghị adị mkpa). Maka ntụzịaka kacha zie ezi na nke zuru oke gbasara ịdọ aka ná ntị ndị sitere na ngwa ndakọrịta nke Intel® DPC++, lee ngalaba ịdọ aka ná ntị okwu na Migrated Code nke GỤKWUO files.

IHE Iji chịkọta ndị akwagara sample, tinye -I/gụnye na iwu mkpokọta gị.

Maka mgbagwoju anya sample ntuziaka, lee Buga oru ngo ngalaba nke Intel® DPC++ Ndakọrịta Ngwa Ntuziaka na ntụnye aka.
