Hi all, I am a newbie and know very little about gem5. Now I want to emulate a rack-scale non-coherent cache machine using gem5, but I totally have no idea where I should start. Instead of simulate a complete rack-scale machine, such as THE MACHINE in hp, I only focus on some particular aspects of simulated system.
Namely the system has 1. some nodes and there is a global memory shared by all the nodes. 2. each node has its private cache (L!/L2/L3 cache). *But there is no cache coherency across nodes*. 3. each node can run its own operating system instance. (those instances maybe different or same) Before I try to use multiple qemu instances and the "ivshmem" device for this simulation. But the qemu approach fails to provide non-coherent cache, so I resort to gem5 now. Could anyone give me some hints to simulate above architecture using gem5? Any related material or information are helpful. Thanks so much!!
