O le .stf file tatala i le Itulau Aotelega view, lea e fai ma sui o fa'amatalaga lautele e uiga i lau fa'atinoga o talosaga:FAAMANATU Mo nisi fa'amatalaga e uiga i le Intel Trace Analyzer ma le Collector functionality, va'ai Aoao Atu.

Iloilo galuega a le MPI sili ona malosi

Iloilo se amio talosaga MPI, su'e fagu ma fa'ailoa fa'asologa e su'e ai auala e fa'aleleia atili ai le fa'atinoga o talosaga.

1. Mai le Aotelega Itulau tatala le Taimi Taimi view e ala i le kilikiina o le Fa'aauau> Siata> Taimi Fa'asologa mo le su'esu'eina loloto o galuega a le MPI pito i luga.
   O lo'o fa'aalia e le siata gaioiga fa'agasologa ta'itasi ile taimi.
   O galuega fa'aoga o lo'o fa'aauau pea, lea o fa'amatalaga ta'itasi e aofia ai se vaega fa'akomepiuta ma feso'ota'iga MPI.
2. Fa'ailoa se su'esu'ega se tasi e taula'i i ai ma fa'asolo i totonu e ala i le tosoina o lau isumu i luga o le taimi mana'omia:Le fa'ailoga view fa'aalia le vaega i totonu o le fa'asologa na e filifilia. O lo'o fa'aalia e le siata Taimi o Mea na tutupu mea na tutupu i le taimi o le su'esu'ega filifilia.
   • Fa'alava fa'asaga e fai ma sui o faiga fa'atasi ma galuega e ta'ua i nei faiga.
   • O laina uliuli e fa'ailoa mai ai fe'au na lafo i le va o faiga. O nei laina e feso'ota'i ai le felauaiga ma le mauaina.
   • O laina lanumoana e fa'atusalia ai galuega fa'atasi, e pei o fa'asalalauga po'o fa'aitiitia galuega.
3. Su'e ile Flat Profile tab (A) e vaʻavaʻai totoʻa ai i galuega faʻatino i le taimi o loʻo e filifilia (filifilia i le Taimi Taimi.
4. Ungroup MPI e fa'atino e au'ili'ili le fa'agaioiga o le MPI i lau talosaga.
   Ina ia faia lenei mea, kiliki i luga ole All Processes> Group MPI (B) ile Flat Profile ma filifili UngroupMPI. O lenei gaioiga e faʻaalia ai le MPI taʻitasi.
5. Iloilo faʻagasologa o fesoʻotaʻiga ma o latou tuaoi tuusaʻo e faʻaaoga MPI_Sendrecv i le amataga o le faʻamatalaga. Mo exampLe:
   • a. I le sample, o le MPI_Sendrecv faʻamatalaga faʻamatalaga o loʻo i ai se fagu: o le faagasologa e le fesuiaʻi faʻamatalaga ma lona tuaoi e sosoo ai seia maeʻa le fesuiaiga ma le muamua. Le Fa'asologa o Taimi view fa'aalia le fagufa'ailoga lea e pei o se fa'asitepu.
   • e. O le MPI_Allreduce i le fa'ai'uga o le fa'asologa e toe fa'afetaui uma faiga; o le mafuaaga lena o lenei poloka ua i ai foliga faafeagai faasitepu.
6. Fa'ailoa fa'asologa, fa'aaoga le Function Profile ma le Message Profile views.
   • a. Tatala siata i le taimi e tasi:
     I le Galuega Profile siata, tatala le Load Balancetab.
   • Alu i le lisi lisi e tatala ai le Message Profile.
   • e. I le Load Balance tab, faʻalautele MPI_Sendrecv ma MPI_Allreduce. O le Load Balancing o loʻo faʻaalia ai o le taimi faʻaalu i MPI_Sendrecv faʻateleina i le numera o le faagasologa, ae faʻaitiitia le taimi mo MPI_Allreduce.
   • i. Su'esu'e le Message Profile Siata i lalo ile tulimanu taumatau pito i lalo.
     O le lanu lanu o poloka o loʻo faʻaalia ai o feʻau o loʻo faimalaga mai se tulaga maualuga i se tulaga maualalo e manaʻomia le tele o le taimi ae o feʻau o loʻo faimalaga mai se tulaga maualalo i se tulaga maualuga e faʻaalia ai se ituaiga vaivai e le masani ai:

O faʻaiʻuga o suʻesuʻega faʻatusatusa o loʻo faʻaalia ai e leai ni faʻataʻitaʻiga lavelave faʻafeiloaʻiga i totonu o le talosaga, o le fefaʻatauaʻiga e faia naʻo faiga tuaoi. O fa'amatalaga o le a taua mo le Fa'aleleia o lau Fa'atinoga o Talosaga e ala i le Suia o Feso'ota'iga la'asaga e fa'asilisili ai le fa'ata'ita'iga feso'ota'iga o le talosaga.

Fa'ailoa Feso'ota'iga le paleni

Mataʻituina lau talosaga i lalo o tulaga lelei ma faʻatusatusa le ata muamua file fa'atasi ai ma le fa'ata'ita'iga e fa'ate'aina fa'afitauli fa'afitauli.

1. Fausia se faʻataʻitaʻiga file:
   • a. Filifili Advanced> Idealization pe kiliki le (Idealization) faamau meafaigaluega.
   • e. Siaki le fa'ata'ita'iga fa'ata'ita'iga ile pusa fa'atalanoaga Fa'ata'ita'i (fa'ailoga lelei file igoa ma le taimi mo le liua).
   • i. Kiliki Amata e fa'ata'atia ai lou fa'asologa.
2. Fa'atusatusa le ulua'i fa'asologa ma le fa'asologa fa'apitoa:
   • a. Filifili Advanced> Imbalance Diagram pe kiliki le (Imbalance Diagram) faamau meafaigaluega.
   • e. I le Imbalance Diagram dialog box, kiliki le Open Another File fa'amau, fa'afeiloa'i i le fa'asologa fa'apitoa, ma filifili ai.
   • i. I le faʻamalama o le Imbalance Diagram, kiliki le Total Mode button ma filifili le Breakdown Mode.

E mafai ona e vaʻaia o le MPI_Sendrecv o le galuega sili ona faʻaalu taimi. O lo'o fa'aalia le mamafa le paleni i totonu
lanu malamalama ma e aofia ai le 10% mo le galuega MPI_Sendrecv. O le taimi lea e fa'aalu ai faiga e fa'atali ai le tasi i le isi.

Fa'aleleia lau Fa'atinoga o Talosaga e ala i le Suia o Feso'ota'iga

1. Faʻaleleia le faʻatinoga o le talosaga a le MPI e ala i le suia o le poloka i fesoʻotaʻiga e le poloka.
   I lau code sui le MPI_Sendrcv serial ma le le poloka fesootaiga: MPI_Isend ma MPI_Irecv. Mo example: Uluai fa'ailoga snippet:

   // lafo i luga le laina mulimuli
   MPI_Send(gr->x_new[gr->lrow], gr->lcol+2, MPI_DOUBLE, gr->up, 200, MPI_COMM_WORLD);
   MPI_Recv(gr->x_new[0], gr->lcol+2, MPI_DOUBLE, gr->lalo, 200, MPI_COMM_WORLD, &status_200);
   Fa'aoga le Intel Trace Analyzer Comparison view e fa'atusatusa le fa'asologa fa'asologa ma le toe fa'aleleia
   // kopi le koluma agavale i tmp arrays
   afai(gr->agavale != MPI_PROC_NULL){
   gr->x_new[i][gr->lcol+1] = right_col[i]; right_col[i] = gr->x_new[i][gr->lcol];
   // lafo sa'o
   MPI_Send(right_col, gr->lrow+2, MPI_DOUBLE, gr->right, 400, MPI_COMM_WORLD); }
   afai(gr->agavale != MPI_PROC_NULL)
   {
   MPI_Recv(left_col, gr->lrow+2, MPI_DOUBLE, gr->agavale, 400, MPI_COMM_WORLD,&status_400); mo(i=0; i< gr->lrow+2; i++
   {
   gr->x_new[i][0] = left_col[i];
   }
   }
   Fa'afou snippet code
   MPI_Talosaga mana'oga[7];
   // lafo i lalo le laina muamua
   MPI_Isend(gr->x_new[1], gr->lcol+2, MPI_DOUBLE, gr->lalo, 100, MPI_COMM_WORLD, &req[0]);
   MPI_Irecv(gr->x_new[gr->lrow+1], gr->lcol+2, MPI_DOUBLE, gr->up, 100, MPI_COMM_WORLD, &req[1]);
   …..
   MPI_Waitall(7, req, MPI_STATUSES_IGNORE);
   A fa'asa'o loa, o le fa'asologa e tasi o le talosaga toe fa'aleleia o le a pei o le fa'ata'ita'i leaampLe:
2. Fa'aoga le Intel Trace Analyzer Comparison view e fa'atusatusa le fa'asologa fa'asologa ma le talosaga toe fa'aleleia. Fa'atusatusa fa'ailoga se lua ma le fesoasoani a le Fa'atusatusaga View, ou te alu i View > Fa'atusatusa. O le Faatusatusaga View foliga tutusa i:I le Faatusatusaga View, e mafai ona e vaʻaia o le faʻaaogaina o fesoʻotaʻiga e le taofia e fesoasoani e aveese le serialization ma faʻaitiitia le taimi o fesoʻotaʻiga o faiga.
