Pib ntawm Linux

Ua ntej Koj Pib

Teem Environment Variables
Ua ntej koj tuaj yeem siv lub compiler, koj yuav tsum xub teeb tsa qhov chaw hloov pauv ib puag ncig los ntawm kev nrhiav cov ntawv ib puag ncig siv qhov pib siv hluav taws xob. Qhov no pib tag nrho cov cuab yeej hauv ib kauj ruam.

  1. Txiav txim siab koj lub installation directory, :
    • a. Yog tias koj lub compiler tau teeb tsa hauv qhov chaw nyob los ntawm tus neeg siv hauv paus lossis tus neeg siv sudo, lub compiler yuav raug ntsia hauv / opt/intel/oneapi. Hauv qhov no, yog /opt/intel/oneapi.
    • b. Rau cov neeg siv tsis yog hauv paus, koj cov npe hauv tsev hauv qab intel/oneapi siv. Hauv qhov no,
      yuav yog $HOME/intel/oneapi.
    • c. Rau pawg lossis cov neeg siv kev lag luam, koj pab neeg tswj hwm yuav tau teeb tsa cov compilers ntawm ib lub network sib koom file qhov system. Tshawb xyuas nrog koj cov neeg ua haujlwm admin hauv zos rau qhov chaw teeb tsa
      ( ).
  2. Tau qhov chaw ib puag ncig-setting tsab ntawv rau koj lub plhaub:

Pib ntawm Windows

Ua ntej Koj Pib

Teem Environment Variables
Lub compiler koom ua ke rau hauv cov qauv hauv qab no ntawm Microsoft Visual Studio *:

  • Visual Studio 2022
  • Visual Studio 2019
  • Visual Studio 2017

Nco tseg Kev them nyiaj yug rau Microsoft Visual Studio 2017 yog deprecated raws li ntawm Intel® oneAPI 2022.1 tso tawm thiab yuav raug tshem tawm yav tom ntej.

Rau kev ua haujlwm tag nrho hauv Visual Studio, suav nrog kev debugging thiab kev txhim kho, Visual Studio Community Edition lossis siab dua yog xav tau. Visual Studio Express Edition tso cai rau cov kab hais kom ua nkaus xwb. Rau tag nrho cov versions, Microsoft C ++ kev txhawb nqa yuav tsum raug xaiv ua ib feem ntawm Visual Studio nruab. Rau Visual Studio 2017 thiab tom qab ntawd, koj yuav tsum siv qhov kev cai nruab los xaiv qhov kev xaiv no.
Koj feem ntau tsis tas yuav teeb tsa ib puag ncig hloov pauv ntawm Windows, raws li cov lus txib-kab lub qhov rais teeb tsa cov hloov pauv no rau koj tau txais. Yog tias koj xav tau teeb tsa ib puag ncig hloov pauv, khiav cov ntawv ib puag ncig raws li tau piav qhia hauv cov ntaub ntawv tshwj xeeb Get Started.
Lub neej ntawd installation directory ( ) yog C:\Program Files (x86)\Intel\oneAPI.

Nruab GPU Tsav Tsheb (yeem)
Txhawm rau tsim thiab khiav daim ntawv thov rau Intel GPUs koj yuav tsum xub nruab Intel GPU tsav tsheb tshiab.

Kev xaiv 1: Siv Cov Kab hais kom ua hauv Microsoft Visual Studio

Intel® oneAPI DPC ++/C ++ Compiler muab ntau yam tsav tsheb:intel-Get-Started-with-the-oneAPI-DPC ++-C++-Compiler-FIG-7 intel-Get-Started-with-the-oneAPI-DPC ++-C++-Compiler-FIG-8

Invoke lub compiler siv cov syntax hauv qab no:intel-Get-Started-with-the-oneAPI-DPC ++-C++-Compiler-FIG-9

Txhawm rau hu lub compiler siv cov kab hais kom ua los ntawm hauv Microsoft Visual Studio, qhib qhov hais kom ua thiab nkag mus rau koj cov lus txib muab tso ua ke. Rau example:intel-Get-Started-with-the-oneAPI-DPC ++-C++-Compiler-FIG-10

Rau SYCL muab tso ua ke, siv qhov kev xaiv -fsycl nrog C ++ tsav tsheb:intel-Get-Started-with-the-oneAPI-DPC ++-C++-Compiler-FIG-11

CEEB TOOM: Thaum siv -fsycl, -fsycl-targets = spir64 yog suav tias yog qhov -fsycl-targets tau teev meej meej hauv cov lus txib.

Kev xaiv 2: Siv Microsoft Visual Studio
Kev them nyiaj yug qhov project rau Intel® DPC ++ / C ++ Compiler hauv Microsoft Visual Studio
Tshiab Microsoft Visual Studio tej yaam num rau DPC ++ tau txais kev teeb tsa los siv Intel® oneAPI DPC ++/C ++ Compiler.
Cov haujlwm tshiab Microsoft Visual C++* (MSVC) yuav tsum tau teeb tsa manually los siv Intel® oneAPI DPC ++/C ++ Compiler.

CEEB TOOM: NET-based CLR C ++ qhov project hom tsis tau txais kev txhawb nqa los ntawm Intel® oneAPI DPC ++ / C ++ Compiler. Cov hom phiaj tshwj xeeb yuav txawv nyob ntawm koj qhov version ntawm Visual Studio, piv txwv liample: CLR Class Library, CLR Console App, lossis CLR Empty Project.

Siv Intel® DPC ++/C ++ Compiler hauv Microsoft Visual Studio
Cov kauj ruam tseeb yuav txawv nyob ntawm qhov version ntawm Microsoft Visual Studio siv.

  1. Tsim ib qhov project Microsoft Visual C ++ (MSVC) lossis qhib qhov project uas twb muaj lawm.
  2. Hauv Solution Explorer, xaiv qhov project (s) los tsim nrog Intel® oneAPI DPC ++/C ++ Compiler.
  3. Qhib Project> Properties .
  4. Nyob rau sab laug pane, nthuav cov Configuration Properties qeb thiab xaiv cov khoom vaj khoom tsev dav dav.
  5. Nyob rau hauv txoj cai pane hloov lub Platform Toolset rau lub compiler koj xav siv:
    • Rau C ++ nrog SYCL, xaiv Intel® oneAPI DPC ++ Compiler.
    • Rau C / C ++, muaj ob lub cuab yeej.
      Xaiv Intel C ++ Compiler (example 2021) invoke icx.
      Xaiv Intel C ++ Compiler (example 19.2) invoke ic.
      Xwb, koj tuaj yeem hais qhia tus qauv sau ua ke raws li cov cuab yeej siv rau txhua qhov kev txhawb nqa platforms thiab teeb tsa ntawm qhov haujlwm xaiv los ntawm kev xaiv Project> Intel Compiler> Siv Intel oneAPI DPC ++ / C ++ Compiler.
  6. Rov tsim dua, siv Build> Project nkaus xwb> Rebuild rau ib qhov project lossis Build> Rebuild Solution rau kev daws teeb meem.

Xaiv Compiler Version
Yog tias koj muaj ntau lub versions ntawm Intel® oneAPI DPC ++ / C ++ Compiler ntsia, koj tuaj yeem xaiv cov version twg koj xav tau los ntawm Compiler Selection dialog box:

  1. Xaiv ib qhov project, tom qab ntawd mus rau Cov Cuab Yeej> Kev Xaiv> Intel Compilers thiab Libraries> > Compilers, qhov twg Qhov tseem ceeb yog C ++ lossis DPC ++.
  2. Siv cov ntawv qhia zaub mov Selected Compiler los xaiv qhov tsim nyog version ntawm lub compiler.
  3. Xaiv OK.

Hloov rov qab mus rau Microsoft Visual Studio C ++ Compiler
Yog tias koj qhov project siv Intel® oneAPI DPC ++ / C ++ Compiler, koj tuaj yeem xaiv hloov rov qab mus rau Microsoft Visual C ++ compiler:

  1. Xaiv koj qhov project hauv Microsoft Visual Studio.
  2. Right-click thiab xaiv Intel Compiler> Siv Visual C ++ los ntawm cov ntawv qhia zaub mov.

Qhov kev txiav txim no hloov kho qhov kev daws teeb meem file siv Microsoft Visual Studio C ++ compiler. Txhua qhov kev teeb tsa ntawm cov haujlwm cuam tshuam tau raug tshem tawm tshwj tsis yog koj xaiv Tsis txhob ntxuav qhov project. Yog tias koj xaiv tsis ntxuav tej yaam num, koj yuav tau rov tsim kho tej yaam num tshiab kom paub tseeb tias txhua qhov chaw files tau muab tso ua ke nrog tus tshiab compiler.

Tsim ib qho kev pab cuam los ntawm kab hais kom ua
Siv cov kauj ruam hauv qab no los sim koj lub teeb tsa compiler thiab tsim ib qho kev pab cuam.

  1. Siv cov ntawv nyeem los tsim ib qho file hu ua hello-world.cpp nrog cov ntsiab lus hauv qab no:
    # suav nrog int main() std::cout << “Hello, world!\n”; rov 0;
  2. Compile hello-world.cpp:
    icx nyob zoo-world.cpp
  3. Tam sim no koj muaj ib tug executable hu ua hello-world.exe uas yuav tsum tau khiav thiab yuav muab tswv yim tam sim:
    nyob zoo-world.exe

Qhov twg outputs:
Nyob zoo, ntiaj teb!

Koj tuaj yeem ncaj qha thiab tswj kev muab tso ua ke nrog kev xaiv compiler. Rau example, koj tuaj yeem tsim qhov khoom file thiab tso tawm qhov kawg binary hauv ob kauj ruam:

  1.  Compile hello-world.cpp:
    icx nyob zoo-world.cpp /c /Fohello-world.obj
    Qhov kev xaiv /c tiv thaiv kev sib txuas ntawm cov kauj ruam no thiab /Fo qhia lub npe rau cov khoom file.
  2. Siv lub icx compiler los txuas cov txiaj ntsig ntawm daim ntawv thov khoom code thiab tso tawm qhov kev ua tiav:
    icx hello-world.obj /Fehello-world.exe
  3. Qhov kev xaiv / Fe qhia txog qhov tsim tau ua tiav file npe. Xa mus rau Compiler Options kom paub meej txog cov kev xaiv muaj.

Compile thiab Execute Sampua Code

Ntau code samples yog muab rau Intel® oneAPI DPC ++/C ++ Compiler kom koj tuaj yeem tshawb xyuas cov yam ntxwv ntawm cov compiler thiab paub koj tus kheej nrog nws ua haujlwm li cas. Rau example:
