I-VTune Profiler iqoqa idatha futhi ibonise imiphumela yokuhlaziya ku-GPU Compute/Media Hotspots viewiphuzu. Ewindini lesifinyezo, bona izibalo zokusebenzisa insiza ye-CPU ne-GPU ukuze uqonde ukuthi uhlelo lwakho lokusebenza luboshelwe yi-GPU. Shintshela ewindini Lezithombe ukuze ubone amamethrikhi ayisisekelo e-CPU ne-GPU amele ukusetshenziswa kwekhodi ngokuhamba kwesikhathi.

Qalisa nge-Intel® VTune™ Profiler ye-macOS*

Sebenzisa i-VTune Profiler ohlelweni lwe-macOS ukwenza ukuhlaziya okuqondiwe okukude kusistimu okungeyona eye-macOS (Linux* noma i-Android* kuphela) .

Awukwazi ukusebenzisa i-VTune Profiler endaweni ye-macOS ngalezi zinhloso:

• UProfile isistimu ye-macOS efakwe kuyo.
• Qoqa idatha ohlelweni lwe-macOS olukude.

Ukuze uhlaziye ukusebenza kwesilawuli kude se-Linux* noma i-Android* kumsingathi we-macOS, yenza esisodwa salezi zinyathelo:

• Qalisa i-VTune Profiler ukuhlaziya ohlelweni lwe-macOS ngohlelo olukude olucaciswe njengokuhlosiwe. Lapho ukuhlaziya kuqala, i-VTune Profiler ixhuma kusistimu ekude ukuze iqoqe idatha, bese ibuyisela imiphumela kumsingathi we-macOS viewing.
• Yenza ukuhlaziya ohlelweni oluqondiwe endaweni bese ukopisha imiphumela kusistimu ye-macOS viewku-VTune Profiler.

Izinyathelo ezikulo mbhalo zithatha isistimu eqondiwe ye-Linux ekude futhi iqoqe idatha yokusebenza kusetshenziswa ukufinyelela kwe-SSH ku-VTune Profiler kuhlelo lokubamba i-macOS.

Ngaphambi kokuthi Uqale

1. Faka i-Intel® VTune™ Profiler ohlelweni lwakho lwe-macOS*.
2. Yakha uhlelo lwakho lokusebenza lwe-Linux ngolwazi lophawu futhi kumodi yokukhishwa ngakho konke ukulungiselelwa okunikwe amandla. Ukuze uthole ulwazi oluningiliziwe, bheka izilungiselelo ze-comiler ku-VTune Profiler usizo.
3. Setha ukufinyelela kwe-SSH kusuka ohlelweni lwe-macOS lokusingatha kuya ohlelweni oluqondiwe lwe-Linux ukuze usebenze ngemodi engenaphasiwedi.

Isinyathelo 1: Qala i-VTune Profiler

1. Yethula i-VTune Profiler ngomyalo we-vtune-gui.
   Ngokuzenzakalelayo, i ngu-/opt/intel/oneapi/.
2. Lapho i-GUI ivuleka, chofoza ENTSHA PROJECT esikrinini Sokwamukela.
3. Ebhokisini elithi Dala Iphrojekthi, cacisa igama lephrojekthi nendawo.
4. Chofoza okuthi Dala Iphrojekthi.

Isinyathelo sesi-2: Lungiselela futhi Uqalise Ukuhlaziya
Ngemva kokudala iphrojekthi entsha, iwindi Lokuhlaziya Lokulungiselela livuleka ngohlobo lokuhlaziya isifinyezo sokusebenza.
Lokhu kuhlaziya kuveza ingqikithiview zezinkinga ezithinta ukusebenza kohlelo lwakho lokusebenza kusistimu eqondiwe.

1. Kufasitelana LAPHO, khetha I-Remote Linux (SSH) futhi ucacise isistimu ye-Linux eqondiwe usebenzisa igama lomsebenzisi@ igama lomethuleli[:port].
   I-VTune Profiler ixhuma kusistimu ye-Linux futhi ifake iphakheji eqondiwe.
2. Kufasitelana elithi WHAT, nikeza indlela eya kuhlelo lwakho lokusebenza ohlelweni lwe-Linux oluqondiwe.
3. Chofoza inkinobho ethi Qala ukuze usebenzise Isifinyezo Sokusebenza kuhlelo lokusebenza.

Isinyathelo 3: View futhi Hlaziya Idatha Yokusebenza
Lapho ukuqoqwa kwedatha kuqedwa, i-VTune Profiler ibonisa imiphumela yokuhlaziya ohlelweni lwe-macOS. Qala ukuhlaziya kwakho efasiteleni lesifinyezo. Lapha, ubona ukusebenza kuphelileview kwesicelo sakho.

The overview ngokuvamile ihlanganisa amamethrikhi ambalwa kanye nezincazelo zawo.

• A Nweba imethrikhi ngayinye ukuze uthole ulwazi oluningiliziwe mayelana nezici ezinomthelela.
• B Imethrikhi ehlatshwe umkhosi ibonisa inani elingaphandle kwebanga lokusebenza elamukelekayo/elivamile. Sebenzisa amathiphu wamathuluzi ukuze uqonde ukuthi ungayithuthukisa kanjani imethrikhi ehlatshwe umkhosi.
• C Bona isiqondiso kokunye ukuhlaziya okufanele ucabange ukukusebenzisa ngokulandelayo. Isihlahla Sokuhlaziya sigqamisa lezi zincomo.

Izinyathelo Ezilandelayo
I-Performance Snapshot iyisiqalo esihle sokuthola ukuhlolwa okuphelele kokusebenza kohlelo lokusebenza nge-VTune Profiler.
Okulandelayo, hlola ukuthi ingabe i-algorithm yakho idinga ukushuna.

1. Qalisa Ukuhlaziya I-Hotspots kuhlelo lwakho lokusebenza.
2. Landela okokufundisa kwe-Hotspots. Funda amasu okuthola okuningi ekuhlaziyweni kwakho kwe-Hotspots.
3. Uma i-algorithm yakho isicutshungulwe kahle, sebenzisa Isifinyezo Sokusebenza futhi ukuze ulinganise imiphumela futhi ukhombe ukuthuthukiswa kokusebenza okungenzeka kwezinye izindawo.
