Abstract

U ovom radu razmatran je utjecaj procesora, cache memorije i vrste RAM-a na performanse kodiranja videa. To je izvedeno simulacijama koristeći gem5-X simulator na superračunalu Bura u Rijeci. Simulacijama su dobiveni rezultati koji su sukladni teoriji koja stoji iza svega toga. Pokazano je kako povećanje veličine cache memorije pozitivno utječe na performanse kao i povećanje asocijativnosti cache memorije. Prilikom razmatranja utjecaja procesora utvrđeno je kako povećanje frekvencije takta poboljšava performanse. Isto tako, tip RAM-a koji ima veću frekvenciju daje bolje rezultate zbog veće propusnosti. Svaka od ovih komponenti ima gornju granicu do koje možemo povećavati razmatrane parametre zbog cijene ili kompleksnosti izvedbe. Kod simulacija s različitim brojem dretvi, rezultati su pokazali kako program s više dretvi ima bolje performanse.

Abstract (english)

In this paper was discussed the impact of processor, cache and type of RAM on performance of encoding video. To make simulations, the gem5-X simulator was used on Bura supercomputer in Rijeka. The simulations provided the results that are consistent with the theory behind all of this. It has been shown that increasing the size of the cache memory has a positive effect on performanse as well as increasing the associativity of the cache memory. When considering the impact of the processor, the results showed that increasing the clock frequency improves performance. Likewise, the type of RAM that has a higher frequency gives better results due to higher bandwidth. Each of these components has an upper limit to which we can increase the considered parameters due to cost or complexity of performance. In simulations with different number of threads, the results showed that a program with more threads has better performance.
