[gem5-users] MSHR full status

Hi all, I think I found in mshr_queue.hh, there is a function called isFull() which can tell whether MSHR is full or not. My following question is that: I run with ruby+alpha+garnet. Will this MSHR still work with Ruby or it just work with simple classic memory? Also is there any way to diffe

culate the latency of the second request which is generated by L1 and sent into the network? Also is there any way I can find L1 data cache miss number and access/hit number of each core? Thanks, -- Xi Chen ___ gem5-users mailing list gem5-users@gem

In the src/mem/protocol/MESI-CMP-directory-L2cache.sm, "int l2_request_latency = 2". I want to change it to " int l2_request_latency = 2*variable" where that "variable" is from another file, say src/mem/aa.hh. Is there anyway to

, then l2_request_latency is 2*(2/1)=4. Basically, I hope to make the number of l2_request_latency to be a variable but not a constant, but I have no idea how to modify the MESI_CMP_directory-L2cache.sm file. Could someone give me some suggestion? Thanks, -- Xi Chen

Hi all, I tried another way to adjust the frequency. Set –clock= to 0.5GHz, 0.33GHz, 0.2GHz, then in the config.ini file the corresponding clock under “system.ruby” became 2,3,5. So the frequency adjustment does work, but the question is why set clock to 2,3,4 GHz, the system does not change an
