Hi Andreas,
Thank you for your quick reply. I really appreciate it.
If I want to do some experiments with NOC network, it seems Ruby is the
only choice, right?
Otherwise I have to use bus connection as you mentioned. Does that
support shared distributed L2 cache and directory coherence?
Is there any available script to model NUMA system so I can take a look?
Thanks

Hi Guojh,
With the current GIC, you are limited to 8 cores. Also note that you
need to create a DTB supporting 8 cores (see separate thread).
When it comes to Ruby, there are some incompatibilities that prevents
it from working with ARM. That said, the non-Ruby memory system is
very configurable, and you can create any tree-shaped NUMA system you
can think of really. If you want more “mesh-like” performance you can
always tune the latencies in the crossbars.
How is that for a work around?
Andreas

Subject: [gem5-users] ARM full system simulation
I want to build a 16 arm core system, connected with mesh network,
which means I have to use Ruby.
Unfortunately from the status matrix, arm and ruby combination
definitely doesn't work together.
Is there any workaround?
Thanks
