Re: [marss86-devel] Using Dramsim2 for more than 4G memory size

[Seyed Majid Zahedi]

Paul, I increased the number of channels to two, and was able to simulate for 8G of RAM. Is there any limitation on the capacity that each channel can handle?

The DRAMSim2 code is so deep in the simulation code of marss that it shouldn't have a direct impact on something like launching QEMU.  I have been meaning to push out a bunch of changes but I'm currently busy working on other things.  On Mon, May 6, 2013 at 5:23 PM, seyed <s.majid.zah...@gmail.com> wrote: Hi, I'm trying to simulate a machine with more than 4G memory size. running 'free -m' on my own machine gives me:              total       used       free     shared    buffers     cached Mem:         64419      18475      45943          0        366       7571, which means that I have enough memory on my own machine to launch qemu with more than 4G memory. I tried 20G memory size with marss (without DRAMSim2), and it works. However, running the same config with marss.dramsim doesn't work. Actually, it gets stuck after redirecting to /dev/pts/*. I also tried 8G and 12G, but non of them worked for me. Does anyone have the same experience?
