[Gems-users] built-in topology

["Zhang Yu" <thuzhangyu@xxxxxxxxx>]

Hi,

I have some questions about the torus_2d built-in topology in ruby (garnet_fixed_pipeline).

Environment:

16 processors, 1processor per chip, 16 memory banks.

1. There are 16 routers in total. Each router has 7 input links and 7 output links. How is the router connected to the L1 cache, L2 cache and memory directory. For example, for router_0, which link is connected to L1, L2 and memory, respectively?
2. How are the routers connected to each other? Where do the output links of  router_0  go? e.g. where does link 4 of router_0 go?

Thanks,
Yu
