CMU-SAFARI / ramulator2

Ramulator 2.0 is a modern, modular, extensible, and fast cycle-accurate DRAM simulator. It provides support for agile implementation and evaluation of new memory system designs (e.g., new DRAM standards, emerging RowHammer mitigation techniques).

SimpleO3 front end show significant Cache bandwidth bound when doing sequential memory access test. #49

Dear Author, While conducting a single core sequential memory read-only test on LPDDR5 6400, I noticed that the system bandwidth is constrained by cache performance with all default settings, rather than by the DRAM. Only when I modify the Cache latency to 1, I can find the effect of different memory bandwidth configurations. I want to know why it happens since it is not likely to be cache bound in the real system to do such a test.
