[gem5-users] 3D MESH TOPOLOGY DEVELOMENT IN GARNET2.0

[Idris M. Umar]

I want to modify the Mesh_XY topology in Garnet2.0 to create a 3D topology. I used Mesh_XY as a base layer to which a replicated layer is added with the MakeTopology function. Then I established the necessary bridge links. It works fine with table routing, but always produced a segmentation error when the XY routing is applied. Can someone please help me out? I can attached my scripts when asked to.

Thanks for your expected cooperation.

Table routing by default does XY for a 2D Mesh - since all X links have a weight of 1 and Y links have a weight of 2. You can give weights of 3 for your Z links to get a XYZ routing algorithm for instance.
The specific XY routing function inside Garnet only works for a 2D mesh as it routes assuming link directions of N/S/E/W and will not work for your 3D topology. I only recommend using it to study adaptive routing algorithms in a 2D Mesh for instance.
