Hi Ahmad,
This is why we created the event-based DRAM model that you find integrated in
src/mem/SimpleDRAM.py. Is there any particular reason why you are not using
that model? It's faster, and far more extensible.

Subject: [gem5-users] Slow DRAMSim2 on Gem5 FS
Hi,
I have integrated DRAMSim2 with Gem5 to make it work with FS mode. There are no
errors but the simulation speed is very slow. In atomic CPU mode, the linux
boot up doesn't finish even in 8 hours. Where as without DRAMSim2, linux boots
up in 3 min on Gem5 FS mode.
I debugged the problem and I found out that the problem is due to the DRAMSim2
memory controllers 'update' method which is called on each dram clock cycle to
update the background energy. It is not possible to run any benchmark due to
this.
Has anyone addresses this problem before please?
cheers, Ahmad
