Qalisa nge-Intel® enye ye-API enye yeThala leeNcwadi loHlalutyo lweDatha ye-API
Ithala leencwadi le-Intel® oneAPI Data Analytics (oneDAL) lithala leencwadi elinceda ukukhawulezisa uhlalutyo lwedatha enkulu ngokubonelela ngeebhloko zokwakha eziphuculweyo ze-algorithmic kuzo zonke s.tagi-es of analytics yedatha (ukulungiswa kwangaphambili, ukuguqulwa, ukuhlalutya, ukulinganisa, ukuqinisekiswa, kunye nokwenza izigqibo) kwi-batch, i-intanethi, kunye neendlela ezisasazwayo zokubala. Ngolwazi ngokubanzi malunga ne-oneDAL, ndwendwela iphepha elisemthethweni le-oneDAL.
Ngaphambi kokuba Uqale
oneDAL ibekwe ngaphakathi / dal directory apho lulawulo apho i-Intel® oneAPI Base Toolkit ifakwe khona.
Inguqulelo yangoku ye-oneDAL enenkxaso yeSYCL iyafumaneka kwiLinux* kunye neWindows* 64-bit yeenkqubo zokusebenza. Amathala eencwadi e-oneDAL awakhelwe kwangaphambili anokufumaneka kwi /idal/ /chasa ulawulo.
Ukufunda ngeemfuno zenkqubo kunye nokuxhomekeka okufunekayo ukwakha examples, bhekisa kwi IiMfuno zeNkqubo iphepha.
Isiphelo ukuya ekupheleni Eksample
Apha ngezantsi ungafumana ukuhamba komsebenzi okuqhelekileyo kwe-algorithm ye-oneDAL kwi-GPU. Example ibonelelwe kwi-Principal Component Analysis algorithm (PCA).
La manyathelo alandelayo abonisa indlela yokwenza:
- Funda idatha evela CSV file
- Qhuba uqeqesho kunye nemisebenzi ye-inference ye-PCA
- Ukufikelela kwiziphumo eziphakathi ezifunyenwe kuqeqesho stage
- Bandakanya oku kubhalwe ngasentla kwekhasi kulandelayo okwenza zonke izibhengezo ze-oneDAL zifumaneke.
- Yenza umgca weSYCL* ngomkhethi wesixhobo esifunekayo. Kule meko, umkhethi we-GPU usetyenziswa:
const auto queue = sycl::umgca{sycl::gpu_umkhethi{}}; - Ekubeni zonke izibhengezo ze-oneDAL zikwisithuba segama se-oneapi::dala zonke izibhengezo ezivela kwisithuba segama se-oneapi ukuze kusetyenziswe idal endaweni ye-oneapi::dal ye-brevity: usebenzisa isithuba segama i-oneapi;
- Sebenzisa umthombo wedatha ye-CSV ukufunda idatha esuka kwi-CSV file kwitafile:
const auto data = dal::funda (umgca, dal::csv::umthombo wedatha{“data.csv”}); - Yenza inkcazo ye-PCA, lungiselela iiparamitha zayo, kwaye usebenzise i-algorithm yoqeqesho kwidatha elayishwe kwi-CSV.
- Shicilela ii-eigenvectors ezifundiweyo:
- Sebenzisa imodeli eqeqeshiweyo ukuthelekelela ukunciphisa ubungakanani bedatha:
Yakha kwaye Uqhube ExampLes
Yenza la manyathelo alandelayo ukwakha kunye nokuqhuba exampLes ebonisa iimeko ezisisiseko zokusetyenziswa kwe-DAL enye enenkxaso ye-SYCL. Yiya e /idal/ kwaye emva koko umise imeko-bume njengoko kubonisiwe kwi-example ngezantsi:
PHAWULA Wonke umxholo ongezantsi oqala nge # uthathwa njengophawu kwaye akufanele uqhutywe ngekhowudi.
- Cwangcisa imeko-bume efunekayo ye-DAL enye (izinto eziguquguqukayo ezifana ne-CPATH, UMENDO_WETHALABHALA, kunye ne-LD_LIBRARY_PATH):
• Kwi-Linux, kukho iindlela ezimbini ezinokwenzeka zokuseta imeko-bume efunekayo: nge-vars.sh script okanye ngemodyuli files.
• Ukumisela imeko-bume ye-DAL enye nge-vars.sh script Yenza lo myalelo ulandelayo:
umthombo ./env/vars.sh
• Ukumisela imeko-bume ye-DAL enye ngemodyuli files
Qalisa1. iimodyuli: umthombo $MODULESHOME/infit/bash
PHAWULA Jonga kumaxwebhu eeModyuli zeNdalo ngeenkcukacha.
Ukubonelela2. iimodyuli ezinendlela eya kumnqongo files ulawulo: imodyuli
sebenzisa ./modyuli files
Qhuba i-3.modyuli:
umthwalo wemodyuli dal
• Kwi-Windows, sebenzisa lo myalelo ulandelayo:
/env/vars.bat - Khuphela ./exampLes/neap/dip kulawulo olubhalekayo ukuba kuyimfuneko (ekubeni isenza okwethutyana files):
cp ./examples/oneapi/dpc ${WRITABLE_DIR} - Cwangcisa imeko-bume yomqokeleli ye-Intel® enye i-API DPC++/C++ Compiler. 'Yabona Qalisa nge-Intel® oneAPI DPC++/C++ Compiler ngeenkcukacha.
- Yakha kwaye uqhube i-exampOku kubonisa indlela yokusebenzisa i-DAL enye ngenkxaso yeSYCL:
PHAWULA Kufuneka ube neemvume zokubhala kwi exampincwadi encinci yokwakha examples, kwaye wenze iimvume zokuziqhuba. Kungenjalo, kufuneka ukope examples/oneapi/dpc kunye nomxamples/ oneapi/iincwadi ezinenkcukacha kulawulo lweemvume ezichanekileyo. Ezi folda zimbini kufuneka zigcinwe kwinqanaba elifanayo lolawulo ngokunxulumene enye kwenye.
• Kwi-Linux:
• Kwi-Windows:
- Ukubona zonke iiparamitha ezikhoyo zenkqubo yokwakha, chwetheza yenza kwiLinux* okanye ungayenzi kwiWindows*.
Isiphumo example binaries kunye nelog files zibhalwe kwi _results directory.
PHAWULA Kufuneka uqhube i-exampkancinci kwi examples/oneapi/dpc ifolda, hayi ukusuka _iziphumo zefolda. Uninzi lwangaphambiliampLes ifuna idata ukuba igcinwe kwi examples/oneapi/data kunye nokuba nekhonkco elizalanayo kuyo iqalwe ukusuka kwi-examples/enyeapi/dip incwadi.
Unokwakha i-C ++ yemveliampLes ibekwe kwi-examples/oneapi/cup incwadi eneenkcukacha ngendlela efanayo.
Qokelela kwaye wakhe usetyenziso ngepkg-config
Isixhobo se-pkg-config sisixhobo esisetyenziswa ngokubanzi sokwakha isoftware enokuxhomekeka. Intel® enye API Data Analytics Library inikeza files nge pug-config metadata yokuqulunqa nokudibanisa isicelo kwithala leencwadi.
Misela okusingqongileyo
Ukusebenzisa i-pug-config, yakha ithala leencwadi kwaye emva koko umise imeko-bume usebenzisa i-vars.sh okanye i-vars.bat scripts:
- Kwi-Linux: umthombo ./env/vars.sh
- KwiWindows: /env/vars.bat
Khetha imetadata file
Imetadata files inikezelwe ngekhava enye ye-DAL kuphela uqwalaselo lwesixhobo esisingisele kwi-64-bit Linux, macOS, okanye inkqubo yokusebenza yeWindows yeC++.
Khetha imetadata file Ngokusekwe kwimowudi enye ye-DAL yokuthunga kunye nendlela yokudibanisa oyisebenzisayo:
enye i-DAL pug-config metadata files
| Umsonto omnye (ongenamsonto) | Imisonto emininzi (yangaphakathi) | |
| Ukudibanisa okuzinzileyo | i-dal-static-sequential-host | I-dal-static-threading-host |
| Unxulumaniso olunamandla | i-dal-dynamic-sequential-host | I-dal-dynamic-threading-host |
Qokelela inkqubo usebenzisa i-peg-config
Ukuqokelela inkqubo yovavanyo lwe-cpp nge-DAL enye kunye ne-peg-config, nika igama lenye ye-DAL pug-config metadata. file njenge parameter yegalelo. Umzekeloample:
- KwiLinux okanye kwiMacOS:
ice test.cpp pug-config -flags -libs dal-dynamic-threading-host - KwiWindows:
ye/F “delimbs=,” % i ku ('pug-config –flags –libs dal-dynamic-threading-host) yenza icl test.cpp%i
A sample khowudi ye svm_two_class_thunder_dense_batch example ngenkxaso yeSYCL. Qhuba oku kulandelayo kwi-examples/oneapi/cpp ulawulo: - KwiLinux okanye kwiMacOS:
icc -I source/ source/svm/svm_two_class_thunder_dense_batch.cpp icc test.cpp pkg-config -cflags -libs dal-dynamic-threading-host - KwiWindows:
for /F “delis=,” % i ku ('peg-config –flags –libs dal-dynamic-threading-host) do ill -I source/ ill svm_two_class_thunder_dense_batch.cpp %i
