Sebenzisa iVTune Profiler kwinkqubo ye-macOS ukwenza uhlalutyo lwethagethi ekude kwi-non-macOS inkqubo (Linux* okanye i-Android* kuphela) .

Awukwazi ukusebenzisa iVTune Profiler kwindawo ye-macOS ngezi njongo:

• UProfile inkqubo ye-macOS efakwe kuyo.
• Qokelela idatha kwinkqubo ekude ye-macOS.

Ukuhlalutya ukusebenza kweLinux* okanye i-Android* ekujoliswe kuyo kwinginginya ye-macOS, yenza elinye lala manyathelo:

• Qhuba iVTune Profiler uhlalutyo kwinkqubo ye-macOS enenkqubo ekude echazwe njengento ekujoliswe kuyo. Xa uhlalutyo luqala, iVTune Profiler iqhagamshela kwisistim ekude ukuqokelela idatha, emva koko izisa iziphumo kwinginginya ye-macOS ye viewnge.
• Yenza uhlalutyo kwisistim ekujoliswe kuyo kwindawo kwaye ukhuphele iziphumo kwinkqubo ye-macOS ye viewkwiVTune Profiler.

Amanyathelo kolu xwebhu athatha inkqubo ekujoliswe kuyo yeLinux ekude kwaye aqokelele idatha yokusebenza usebenzisa ufikelelo lwe-SSH ukusuka kwiVTune Profiler kwindlela yokusingatha i-macOS.

Ngaphambi kokuba Uqale

1. Faka i-Intel® VTune™ Profiler kwinkqubo yakho ye-macOS*.
2. Yakha usetyenziso lwakho lweLinux ngolwazi lwesimboli nakwimowudi yokuKhupha ngalo lonke ulungiselelo olwenziweyo. Ngolwazi oluneenkcukacha, bona useto lomqokeleli kwiVTune Profiler uncedo.
3. Cwangcisa ufikelelo lwe-SSH ukusuka kwinginginya ye-macOS inkqubo ukuya kwinkqubo yeLinux ekujoliswe kuyo ukuze usebenze kwimowudi engaphantsi kwegama-lingaphantsi.

Inyathelo 1: Qala iVTune Profiler

1. Qalisa iVTune Profiler ngomyalelo we-vtune-gui.
   Ngokungagqibekanga, i yi/opt/intel/oneapi/.
2. Xa i-GUI ivula, cofa ENTSHA IPROJECT kwiscreen sokwamkela.
3. Kwi Dala ibhokisi yencoko yababini yeProjekthi, khankanya igama leprojekthi kunye nendawo.
4. Cofa Yenza iProjekthi.

Inyathelo 2: Lungiselela kwaye Uqhube Uhlahlelo
Emva kokuba uyile iprojekthi entsha, ifestile yoHlahlelo loLungiselelo ivula ngohlobo lohlalutyo lweSifinyezo soMsebenzi.
Olu hlalutyo lubonisa ngaphezuluview kwimiba echaphazela ukusebenza kwesicelo sakho kwinkqubo ekujoliswe kuyo.

1. Kwifestile APHO, khetha i-Remote Linux (SSH) kwaye ukhankanye inkqubo ye Linux ekujoliswe kuyo usebenzisa igama lomsebenzisi@ igama lenginginya[:port].
   VTune Profiler idibanisa inkqubo ye Linux kwaye ihlohla iphakheji ekujoliswe kuyo.
2. Kwifestile ye-WHAT, nikeza umendo kwisicelo sakho kwindlela ye Linux ekujoliswe kuyo.
3. Cofa iqhosha lokuQalisa ukwenza umfanekiso oqingqiweyo kwisicelo.

Inyathelo loku-3: View kunye noHlalutya iDatha yokuSebenza
Xa uqokelelo lwedatha lugqiba, iVTune Profiler ibonisa iziphumo zohlalutyo kwinkqubo ye-macOS. Qala uhlalutyo lwakho kwiSishwankathelo sefestile. Apha, ubona ukusebenza kuphelileview kwesicelo sakho.

I-overview Ibandakanya iimetrikhi ezininzi kunye neenkcazo zazo.

• A Yandisa i-metric nganye ngolwazi oluneenkcukacha malunga nezinto ezinegalelo.
• B I-metric ephawulweyo ibonisa ixabiso elingaphandle koluhlu lwamkelekileyo/oluqhelekileyo lokusebenza. Sebenzisa iingcebiso zesixhobo ukuqonda indlela yokuphucula i-metric ephawulweyo.
• C Jonga isikhokelo kolunye uhlahlelo onokuthi ucinge ukuluqhuba ngokulandelayo. Umthi wokuHlalutya ugxininisa ezi ngcebiso.

Amanyathelo Alandelayo
I-Snapshot yokuSebenza sisiqalo esihle sokufumana uvavanyo olupheleleyo lokusebenza kwesicelo ngeVTune Profiler.
Okulandelayo, khangela ukuba i-algorithm yakho ifuna ukulungiswa.

1. Qhuba uHlahlelo lweeHotspots kwisicelo sakho.
2. Landela isifundo se-Hotspots. Funda ubuchule bokufumana okuninzi kuhlalutyo lwakho lweeHotspots.
3. Nje ukuba i-algorithm yakho ilungiswe kakuhle, sebenzisa i-Snapshot yokuSebenza kwakhona ukuze ulungelelanise iziphumo kwaye uchonge uphuculo olunokuthi lubekho kwezinye iindawo.
