[gem5-users] Add new command-line option for simulation

Hello, I want to add few new command-line options for my simulations. I wanted to understand how to write code for that. For example, in garnet_synth_traffic.py, I can mimic code lines like other options using parser.add_option, but I wanted to know where is the constructor

Also, could you let me know if this seems okay: As per 4th (Marc Orr) and 6th (Jason) replies in https://groups.google.com/g/gem5-gpu-dev/c/Wt43jSYYXag, the value returned by functional access gets overwritten with a value from the backing store, thus a functional read returning true always

[gem5-users] FAST-FORWARD Option in Simulation

Hello, Please help me to know how to use the Fast Forward Option so that I can get statistics for simulation excluding the initial Cache misses. I had specified --fast-forward=1000 but in the stats file everything is 0. I am using Ruby system with garnet network. Following is the message on

[gem5-users] L1Cache Controller Statistics

Hello, I need to get values for a new statistic I have added to Abstract Controller, similar to fully_busy_cycles. In the collateStats() function in StateMachine.py , I added the code to calculate the new statistic at the end of the simulation. However, only L1CacheController-0,

[gem5-users] Re: Interface Message Buffers between the Network and the Ruby protocol

Hi, thank you! So based on Dest NI it is decided that the packet is for L1CACHE (0-15), L2CACHE(16-31) or DIRECTORY (32-47), and vnet(0,1,2) decides which queue, right? I also wanted to know how the route.dest_ni is used? I didn't come across code where dest_ni is used at the destination

ess the stats before dumping, you can create another function for callback, for example, localCollateStats(), and register it as a dump callback in the constructor. Regards, Jiayi On Tue, May 18, 2021 at 11:35 AM VEDIKA JITENDRA KULKARNI via gem5-users mailto:gem5-users@gem5.org>> wrote:
