[gem5-users] No system.physmem.store0.pmem generated in checkpoints

I want to create checkpoints using MOESI_hammer +ruby. I used command: ./build/X86_MOESI_hammer/gem5.fast configs/example/se.py -n 1 --cpu-type=timing --bench bzip2 --ruby -I 10 --checkpoint-dir=tmpdir --checkpoint-at-end However I only got two files in the checkpoint folder: m5.cpt syst

Prateek, Don't know what is config.dot.py but with config.dot.pdf you can easily verify the connections. On 4/4/14, Prateek Gupta wrote: > Hello Andreas, > > > Thanks for your reply. > Do I need to extend fs.py or se.py? I have tried making changes in > CacheConfig.py, Caches.py and > Options.py

Re: [gem5-users] gem5 cache latency, impact on performance

Sanem, maybe you put sleep() somewhere in the code that never executes! Can you confirm that by breakpoints? On 4/4/14, Sanem Arslan wrote: > Hi all, > > I am using classic memory system and I have added several codes to > the "cache_impl.hh" and "blk.hh" files. However I cannot see the > perfor

[gem5-users] Gem5 Prefetcher

I am currently trying to use the gem5 prefetcher and have edited the CacheConfig.py file to include the default StridePrefetcher() attached to both the data and the l2 cache. However, I am always receiving 0's for all prefetcher data in the stats.txt file and can't seem to figure out why. I

[gem5-users] gem5 cache latency, impact on performance

Hi all, I am using classic memory system and I have added several codes to the "cache_impl.hh" and "blk.hh" files. However I cannot see the performance overhead of these added codes on the gem5 execution time. I have increased cache latency parameters from "CacheConfig.py" file and I can

[gem5-users] Minimum requirement of l1d cache size?

Hi, I’m trying to figure out how to modify cache size of gem5 with ruby memory subsystem, but seems if the l1d cache size is lower than 64kB, there will be a kernel panic under SE model. The command I’m using is: ./build/X86/gem5.opt configs/example/se.py --ruby --caches —l1d_size=64kB -c ./t

Re: [gem5-users] modeling L3 last level cache in gem5

Hello Andreas, Thanks for your reply. Do I need to extend fs.py or se.py? I have tried making changes in CacheConfig.py, Caches.py and Options.py as follows: Options.py: I add this new option parser.add_option("--l3cache", action="store_true") Caches.py: I add the L3 cache class L1Cache(B

Re: [gem5-users] modeling L3 last level cache in gem5

Hi Prateek, The classic memory model has all the bits you need. There is a DRAM controller, and you can create as many levels of caches as you want (and stripe across as many different L3s as you please). You should be fine simply extending the fs.py or se.py script to make sure one or more L3s ar
