Ongorora Anonyanya Kushanda MPI Mabasa

Ongorora maitiro ekushandisa kweMPI, tsvaga mabhodhoro uye uone serialization kuti uwane nzira dzekuvandudza mashandiro ekushandisa.

1. Kubva paKupfupisa Peji vhura iyo Chiitiko Nguva view nekudzvanya Ramba > Machati > Chiitiko Nguva yekuongorora kwakadzama kwepamusoro MPI mabasa.
   Chati inoratidza mabasa ega ega nekufamba kwenguva.
   Basa rekushandisa rinodzokororwa, apo imwe neimwe iteration ine chikamu checomputational uye MPI kutaurirana.
2. Ziva imwe iteration yekutarisa uye kuswededza mairi nekukweva mbeva yako pane inodiwa nguva yenguva:The trace view inoratidza chikamu chiri mukati mekutsvaga kwawasarudza. Chati yeChiitiko cheNguva inoratidza zviitiko zvanga zvichiitika panguva yakasarudzwa.
   • Horizontal bars inomiririra maitiro ane mabasa anodaidzwa mumaitiro aya.
   • Mitsetse mitema inoratidza mameseji anotumirwa pakati pemaitiro. Iyi mitsetse inobatanidza kutumira nekugamuchira maitiro.
   • Mitsetse yebhuruu inomiririra mashandiro akaungana, akadai sekutepfenyura kana kuderedza mashandiro.
3. Chinja kuFlat Profile tab (A) kuti utarise zvakanyanya pamabasa ari kuita panguva iyo iwe (yakasarudzwa muChiitiko Nguva.
4. Ungroup MPI mabasa ekuongorora MPI process chiitiko mukushandisa kwako.
   Kuti uite izvi, tinya-kurudyi Maitiro Ese> Boka MPI (B) muFlat Profile uye sarudza UngroupMPI. Kuvhiya uku kunofumura iyo yega MPI mafoni.
5. Ongorora maitiro ekutaurirana nevavakidzani vavo vakananga vachishandisa MPI_Sendrecv pakutanga kweiyo iteration. For example:
   • a. Musample, iyo MPI_Sendrecv data exchange ine bhodhoro: iyo nzira haitsinhanise data nemuvakidzani wayo anotevera kudzamara kuchinjana neyakapfuura kwapera. The Chiitiko Timelines view inoratidza bhodhoro iri semasitepisi.
   • b. Iyo MPI_Allreduce pakupera kweiyo iteration inowiriranisa maitiro ese; ndosaka iyi block ine reverse staircase kutaridzika.
6. Ziva serialization, uchishandisa iyo Function Profile uye Mharidzo Profile views.
   • a. Vhura machati panguva imwe chete:
     MuBasa Profile chati, vhura iyo Load Balancetab.
   • Enda kuChati menyu kuti uvhure Mharidzo Profile.
   • b. Mune iyo Load Balance tab, wedzera MPI_Sendrecv uye MPI_Allreduce. Iyo Load Bancing inoratidza kuti nguva inoshandiswa muMPI_Sendrecv inowedzera nehuwandu hwekuita, nepo nguva yeMPI_Allreduce ichiderera.
   • c. Ongorora iyo Mharidzo Profile Chati pasi kukona yekurudyi.
     Iko kukodha kwemavara emabhuraki kunoratidza kuti mameseji anofamba kubva padanho repamusoro kuenda padanho repasi anoda nguva yakati rebei nepo mameseji anofamba kubva padanho repasi kuenda pachinzvimbo chepamusoro anoratidza chimiro chisina kusimba kunyangwe-chisinganzwisisike:

Migumisiro yekuenzanisa kuongorora inoratidza kuti hapana maitiro akaoma ekutsinhanisa mukushandiswa, kuchinjana kunoitwa chete nemaitiro ekuvakidzana. Ruzivo urwu ruchave rwakakosha paKuvandudza Mafambiro Ako Yechikumbiro neKushandura Nhanho yeKukurukurirana kukwenenzvera nzira yekutaurirana yechishandiso.

Ziva Disbalanced Communications

Tarisa chikumbiro chako pasi pemamiriro akakodzera uye enzanisa iyo yekutanga trace file neyakarongedzerwa kuparadzanisa kusangana kune dambudziko.

1. Gadzira yakanaka file:
   • a. Sarudza Yepamberi> Idealization kana tinya iyo (Idealization) toolbar bhatani.
   • b. Tarisa iyo idealization paramita muIdealization dialog box (yakanaka trace file zita uye nguva yekushandura).
   • c. Dzvanya Tanga kuti unyatsoita trace yako.
2. Enzanisa tsvakiridzo yepakutanga neicho chakasarudzika:
   • a. Sarudza Yepamberi> Imbalance Dhiagiramu kana tinya iyo (Imbalance Diagram) toolbar bhatani.
   • b. MuImbalance Diagram dialog box, tinya Vhura Imwe File bhatani, famba uchienda kune yakaringana trace, uye sarudza iyo.
   • c. MuImbalance Diagram hwindo, tinya iyo Yese Mode bhatani uye sarudza Breakdown Mode.

Iwe unogona kuona kuti MPI_Sendrecv ndiyo inonyanya kutora nguva basa. Huremu hwekusaenzana hunoratidzwa mukati
ruvara rwakareruka uye rinosanganisira 10% yeMPI_Sendrecv basa. Ino ndiyo nguva iyo maitiro anopedza akamirirana.

Kuvandudza Kuita Kwako Kwekushandisa Nekuchinja Nhaurirano

1. Kuvandudza mashandiro eMPI application nekushandura kuvharira kune kusiri kuvharira kutaurirana.
   Mune kodhi yako tsiva seriyo MPI_Sendrcv nekusavharira kutaurirana: MPI_Isend uye MPI_Irecv. For example: Yekutanga kodhi snippet:
   // muganhu kuchinjana
   Kutsinhana kusina maturo (para* p, grid* gr){
   int i,j;
   MPI_Status status_100, status_200, status_300, status_400;
   // tumira pasi mutsara wekutanga
   MPI_Send(gr->x_new[1], gr->lcol+2, MPI_DOUBLE, gr->down, 100, MPI_COMM_WORLD); MPI_Recv(gr->x_new[gr->lrow+1], gr->lcol+2, MPI_DOUBLE, gr->up, 100, MPI_COMM_WORLD,
   &status_100);
   // tumira mutsara wekupedzisira
   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->down, 200, MPI_COMM_WORLD, &status_200);
   Shandisa Intel Trace Analyzer Comparison view kuenzanisa iyo serialized application neyakadzokororwa
   // kopira kuruboshwe mbiru kune tmp arrays
   kana(gr-> kuruboshwe != MPI_PROC_NULL){
   gr-> x_new[i][gr->lcol+1] = right_col[i]; right_col[i] = gr->x_new[i][gr->lcol];
   // kutumira zvakanaka
   MPI_Send(kurudyi_col, gr->lrow+2, MPI_DOUBLE, gr->kurudyi, 400, MPI_COMM_WORLD); }
   kana(gr-> kuruboshwe != MPI_PROC_NULL)
   {
   MPI_Recv(left_col, gr->lrow+2, MPI_DOUBLE, gr->left, 400, MPI_COMM_WORLD,&status_400); ye(i=0; i<gr->lrow+2;i++
   {
   gr-> x_new[i][0] = left_col[i];
   }
   }
   Yakagadziridzwa kodhi snippet
   MPI_Request req[7];
   // tumira pasi mutsara wekutanga
   MPI_Isend(gr->x_new[1], gr->lcol+2, MPI_DOUBLE, gr->down, 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);
   Kana yagadziriswa, iyo imwe iteration yeyakagadziridzwa application ichaita senge inotevera example:
2. Shandisa Intel Trace Analyzer Comparison view kuenzanisa iyo serialized application neyakadzokororwa. Enzanisa misara miviri nerubatsiro rweKuenzanisa View, kuenda View > Enzanisa. Kuenzanisa View inofanana ne:Mukuenzanisa View, unogona kuona kuti kushandisa kusingavharidzi kutaurirana kunobatsira kubvisa serialization uye kuderedza nguva yekutaurirana kwemaitiro.
