• Fa'atino se VTune Profiler suʻesuʻega i luga o le macOS system ma se masini mamao faʻamaonia e fai ma sini. A amata suʻesuʻega, VTune Profiler e feso'ota'i i le faiga mamao e aoina ai fa'amaumauga, ona toe fa'afo'i lea o fa'ai'uga i le 'au macOS mo viewing.
• Fa'atino se au'ili'iliga ile faiga fa'atatau ile lotoifale ma kopi fa'ai'uga ile faiga macOS mo viewi totonu VTune Profiler.

O laasaga i totonu o lenei pepa o loʻo faʻaogaina se polokalama faʻatulagaina Linux mamao ma aoina faʻamatalaga faʻatinoga e faʻaaoga ai le SSH avanoa mai VTune Profiler i luga o se polokalama talimalo macOS.

Ae e te le'i Amata

1. Fa'apipi'i le Intel® VTune™ Profiler i lau macOS* faiga.
2. Fausia lau talosaga Linux ma faʻamatalaga faʻailoga ma i le Faʻasalalauga faʻatasi ma faʻataʻitaʻiga uma e mafai. Mo fa'amatalaga au'ili'ili, va'ai le fa'apipi'i fa'atulagaina i le VTune Profiler fesoasoani.
3. Seti SSH avanoa mai le host macOS system i le sini Linux system e galue i le password-less mode.

Laasaga 1: Amata VTune Profiler

1. Tatala VTune Profiler ma le vtune-gui poloaiga.
   Ona o le faaletonu, o le o /opt/intel/oneapi/.
2. A tatala le GUI, kiliki NEW PROJECT i le mata Faʻafeiloaʻi.
3. I totonu o le Fausiaina o le Poloketi dialog box, faʻamaonia le igoa o le poloketi ma le nofoaga.
4. Kiliki Fausia Poloketi.

Laasaga 2: Fa'atulaga ma Ta'avale Su'esu'ega
A mae'a ona e faia se galuega fou, e matala le fa'amalama o le Fa'atulagaina o Su'esu'ega i le ituaiga o su'esu'ega o le Fa'atinoga o Ata.
O lenei au'ili'iliga o lo'o fa'ailoa mai ai se fa'aiugaview o fa'afitauli e a'afia ai le fa'atinoga o lau talosaga ile faiga fa'atatau.

1. I totonu ole WHERE pane, filifili Remote Linux (SSH) ma faʻamaonia le faʻaogaina o le Linux system e faʻaaoga ai le igoa ole igoa @ hostname[:port].
   VTune Profiler e fesoʻotaʻi i le Linux system ma faʻapipiʻi le afifi sini.
2. I le WHAT pane, tuʻuina atu le ala i lau talosaga i luga o le polokalama Linux.
3. Kiliki le ki Amata e fa'agasolo ai le ata o le Performance Snapshot ile talosaga.

Laasaga 3: View ma Iloilo Fa'amaumauga Fa'atinoga
A mae'a le aoina o fa'amaumauga, VTune Profiler fa'aalia fa'ai'uga au'ili'ili ile faiga macOS. Amata lau au'ili'iliga ile fa'amalama Aotelega. O iinei, ua e va'ai i se fa'atinoga ua mae'aview o lau talosaga.

Ua umaview e masani ona aofia ai ni metric fa'atasi ma a latou fa'amatalaga.

• A Fa'alautele metric ta'itasi mo fa'amatalaga au'ili'ili e uiga i mea fa'atupu.
• B O se fua fa'atatau e fa'ailoa mai ai se tau i fafo atu o fa'agaioiga masani. Fa'aaoga fautuaga mo meafaigaluega e malamalama ai pe fa'afefea ona fa'aleleia se fua fa'atatau.
• C Va'ai ta'iala i isi au'ili'iliga e tatau ona e mafaufau e fa'agasolo i le isi. O le Analysis Tree o loʻo faʻamaonia ai nei fautuaga.

Laasaga Sosoo
Performance Snapshot o se amataga lelei e maua ai se iloiloga atoa o le fa'atinoga o talosaga ma VTune Profiler.
Le isi, siaki pe manaʻomia e lau algorithm le faʻalogo.

1. Fa'asolo le Su'esu'ega Hotspots i lau talosaga.
2. Mulimuli i se a'oa'oga Hotspots. A'oa'o metotia e maua ai le tele o mea mai au su'esu'ega Hotspots.
3. O le taimi lava e fa'alogo lelei ai lau algorithm, toe ta'e le Performance Snapshot e fa'avasega fa'ai'uga ma fa'ailoa le fa'aleleia atili o fa'atinoga i isi vaega.
