Hello [NetDest (3) 0 1 0 0 - 1 1 0 0 - 0 0 - ] Is a bit mask specifying the controller the packet is bound for, I believe the first 4 0s is the L1 controller, it will be the L1 controller with id 2. (2nd bit set to 1). Then the L2 controllers with ids 0 and 1, the last two bits are the directory id.
However I think you should build binaries with the required coherency protocol option for ruby to work. build/ALPHA_MESI_Two_Level/gem5.fast ________________________________________ De: [email protected] [[email protected]] en nombre de Lang Zhang [[email protected]] Enviado: martes, 04 de marzo de 2014 13:26 Para: [email protected] Asunto: [gem5-users] How the packet gets it's destination node in the source node Good evening, Now I am doing the research about NoC.I use gem5 to simulate. The core will produce a packet and the packet will move from the source node to the destination node.But I'm not sure how the packet gets its destination node in the source code? And after I ran the experiment,i got [RequestMsg: Addr = [0x98ad80, line 0x98ad80] Type = PUTX Requestor = L1Cache-0 Destination = [NetDest (3) 0 1 0 0 - 1 1 0 0 - 0 0 - ] MessageSize = Request_Control DataBlk = [ 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 ]MessageSize=Data Time = 3166840465750000 ] The parameters i used is: build/ALPHA/gem5.opt configure/example/ruby_fs.py --num-cpus=4 --num- dirs=4 --l2caches=4 --topology=Mesh --mesh-rows=2 --garnet-network=fixed -- script=configs/boot/fft.rcS what's the meaning of [NetDest (3) 0 1 0 0 - 1 1 0 0 - 0 0 - ]? Whether it is the destination which the packet should go to? I am trying to get the destination of the packet?Does anyone know how the packet transport? Thanks a lot!
