Hi Tushar,
Thanks for looking into the code, I tried running the Network_test protocol
and got this error:
Global frequency set at 1000000000 ticks per second
info: Entering event queue @ 0. Starting simulation...
gem5.debug:
build/ALPHA_SE_Network_test/mem/ruby/network/garnet/fixed-pipeline/InputUnit_d.cc:78:
virtual void InputUnit_d::wakeup(): Assertion `m_vcs[vc]->get_state() ==
IDLE_' failed.
Program aborted at cycle 30
Aborted
I used this command to run the test-
./build/ALPHA_SE_Network_test/gem5.debug
configs/example/ruby_network_test.py --num-cpus=16 --num-dirs=16
--topology=Mesh --mesh-rows=4 --sim-cycles=1000 --injectionrate=0.01
--synthetic=0 --fixed-pkts --maxpackets=1000 --garnet-network=fixed
On a side note, I also wanted to ask you if Ruby_random_test and
Ruby_mem_test do inject any memory flits in the network. Because, I tried
to dynamic cast the msgptr of these flits to MemoryMessage msgptr so that I
can extract the information about its memory address and type, but it
fails. Do you see any reason why it could be failing? I want to deal with
both network packets and off-chip memory packets in the network. Can you
please guide me which test will be appropriate for the same?
First, the Network test protocol does not access memory. Second, even
other protocols do not send messages to the memory via the network that
you are trying to modify. There are dedicated links between the
directory controllers and the memory controllers.
The test to be used depends on what you want to test for.
