Sažetak

Komunikacione veze među nodovima MPI klastera ponekad predstavljaju usko grlo u njegovom radu. Ovaj problem se manje ili više ublažava ubrzavanjem komunikacionih kanala, a jedan od načina da se to postigne je upotreba višestrukih mrežnih linkova. U ovom radu se porede vremena izvršavanja programa za analizu građevinskih konstrukcija metodom konačnih traka na MPI klasteru uz upotrebu jednog, dva zasebna i dva agregirana mrežna interfejsa po računaru, pri čemu se variraju parametri kao što su broj nodova, vrsta ulaza i vrsta algoritma. Analiza, koja je data na kraju, pokazuje prednosti i mane upotrebe višestrukih mrežnih veza, kada je opravdano njihovo korišćenje i kada i pod kojim uslovima to daje najbolje rezultate.
