[gem5-users] Re: DRAM access rate too high?

Hi Wendy, I’m using the Gem5’s default open-adaptive page policy and the addresses belong to different rows. I also made sure that the same row is not being accessed consecutively. Following is the code I use to pick random address: const size_t mem_size = 1 << 28; char *g_mem; char *pick_addr()

[gem5-users] Re: DRAM access rate too high?

Hi Biresh, What is the page policy and what is the distribution across rows for your access pattern? For example, are these random addresses that should access different rows or is this sequential, in which case, the data will sequence across the column addresses within the same row. Thanks, We

[gem5-users] DRAM access rate too high?

Hello, I’m simulating a 4-core system connected to 1 DRAM bank. For this purpose, I set both the variables ‘ranks_per_channel’ and ‘banks_per_rank’ in the file src/mem/DRAMInterface.py to 1, and then recompile Gem5. Next, I run a single-thread test workload that has 95% cache miss rate and obser

[gem5-users] Committing loads

 Hello all, I’ve been staring at the memory trace of a benchmark and am confused as to why some loads that I expect to commit are not being committed. Note that I am using Ruby. I’ve been tracing the path loads take and it seems to be the following (More information can be found here https:/

Hi, thank you! So based on Dest NI it is decided that the packet is for L1CACHE (0-15), L2CACHE(16-31) or DIRECTORY (32-47), and vnet(0,1,2) decides which queue, right? I also wanted to know how the route.dest_ni is used? I didn't come across code where dest_ni is used at the destination router.
