3. Teem SSH nkag los ntawm tus tswv macOS system mus rau lub hom phiaj Linux system ua haujlwm hauv hom password-tsawg.

Kauj ruam 1: Pib VTune Profiler

1. Tua tawm VTune Profiler nrog vtune-gui hais kom ua.
   Los ntawm default, lub yog /opt/intel/oneapi/.
2. Thaum GUI qhib, nyem NEW PROJECT nyob rau hauv lub npov txais tos.
3. Nyob rau hauv lub Create Project dialog box, qhia lub npe qhov project thiab qhov chaw.
4. Nyem Tsim Project.

Kauj ruam 2: Configure thiab khiav Analysis
Tom qab koj tsim ib qhov project tshiab, Configure Analysis qhov rai qhib nrog cov Performance Snapshot tsom hom.
Qhov kev tshuaj ntsuam no nthuav tawm qhov dhauview ntawm cov teeb meem uas cuam tshuam rau kev ua tau zoo ntawm koj daim ntawv thov ntawm lub hom phiaj system.

1. Nyob rau hauv qhov chaw pane, xaiv tej thaj chaw deb Linux (SSH) thiab qhia meej lub hom phiaj Linux system siv username@ hostname[:port].
   VTune Profiler txuas rau Linux system thiab teeb tsa lub hom phiaj pob.
2. Nyob rau hauv dab tsi pane, muab txoj hauv kev rau koj daim ntawv thov ntawm lub hom phiaj Linux system.
3. Nyem rau Start khawm kom khiav Performance Snapshot ntawm daim ntawv thov.

Kauj ruam 3: View thiab txheeb xyuas cov ntaub ntawv ua tau zoo
Thaum sau cov ntaub ntawv tiav, VTune Profiler qhia cov txiaj ntsig kev txheeb xyuas ntawm macOS system. Pib koj qhov kev tshuaj ntsuam hauv qhov Summary window. Ntawm no, koj pom ib qho kev ua yeeb yam dhauview ntawm koj daim ntawv thov.

Qhov dhauview feem ntau suav nrog ntau qhov ntsuas nrog rau lawv cov lus piav qhia.

• A Nthuav txhua qhov kev ntsuas rau cov ncauj lus kom ntxaws txog qhov muaj feem cuam tshuam.
• B Ib tug chij metric qhia tus nqi sab nraum qhov kev lees txais / kev ua haujlwm li qub. Siv cov lus qhia siv kom nkag siab yuav ua li cas txhawm rau txhim kho qhov ntsuas ntsuas ntsuas.
• C Saib cov lus qhia ntawm lwm qhov kev tshuaj ntsuam koj yuav tsum xav txog kev khiav tom ntej. Tsob Ntoo Analysis qhia txog cov lus pom zoo no.

Cov kauj ruam tom ntej
Performance Snapshot yog qhov pib zoo kom tau txais kev ntsuam xyuas tag nrho ntawm daim ntawv thov kev ua haujlwm nrog VTune Profiler.
Tom ntej no, xyuas seb koj lub algorithm xav tau kev kho.

1. Khiav Hotspots Analysis ntawm koj daim ntawv thov.
2. Ua raws li kev qhia ntawm Hotspots. Kawm cov tswv yim kom tau txais txiaj ntsig zoo tshaj plaws ntawm koj qhov kev txheeb xyuas Hotspots.
3. Thaum koj cov algorithm zoo-tuned, khiav Performance Snapshot dua los ntsuas cov txiaj ntsig thiab txheeb xyuas cov kev ua tau zoo hauv lwm qhov chaw.
