Hey everyone, hope you are doing well.
For my research purposes, I'm using Gem5 in FS mode, with PARSEC benchmark
suite to do some research related to Network-on-Chip.
I have built gem5 using the default command and I'm using 2-D Mesh topology
- python3 `which scons` build/X86/gem5.opt -j n
and I'm also using the default protocol "MESI_Two_Level" defined in the
"./gem5/build_opts/X86" file.
The default protocol uses 3 virtual networks to inject messages.
I want to use only one virtual network instead of using 3 virtual networks.
Can I change the protocol to inject all the messages into one virtual
network? If so, how?
I tried to change the value of virtual_network in these files to be the
same
- gem5/src/mem/ruby/protocol/MESI_Two_Level-dir.sm
- gem5/src/mem/ruby/protocol/MESI_Two_Level-dma.sm
- gem5/src/mem/ruby/protocol/MESI_Two_Level-L1cache.sm
- gem5/src/mem/ruby/protocol/MESI_Two_Level-L2cache.sm
MessageBuffer * requestToDir, network="From", virtual_network="0",
vnet_type="request";
MessageBuffer * responseToDir, network="From", virtual_network="1",
vnet_type="response";
MessageBuffer * responseFromDir, network="To", virtual_network="1",
vnet_type="response";
But I got an assert error when one of the previous files had two identical
"network", and "virtual_network" values.
AssertionError: :
