Anything's possible. But Ruby is not set up to allow multiple physical networks. It would take a fair amount of effort, in my opinion. (I've thought about it, but never tried it.)

Then, is it possible for me to add a network for data? I think if the data network has no order, it should be correct to transfer them directly from cache to cache, right? Will this improve the performance of the protocol? Thanks! There is no separate data network. All messages travel across a single physical network (though there are separate virtual networks for different message types). ...Greg Meng Zhang wrote:

    Hi! I have a question about the data transfer in the MOSI_SMP_bcast
    protocol. I know the address network is totally ordered and the tool
    uses a hierarchical switch to mimic the snooping bus. But I didn't
    find how the data is transferred. Since the data network is not
    ordered, I guess it doesn't need to go though the hierarchical
    switch. However, I didn't find evidence in the code. Could someone
    tell me how the data network looks like? Thanks.
