[gem5-users] Re: run a binary file for 3 times on gem5
Hello, I don't think there's a simple way to do this in SE mode. In FS mode, you could write a simple shell script to execute the program in a loop. One thing you can do is to modify the program to execute the ROI multiple times.

[gem5-users] Re: Error in HMC Simulation
Hey Veronia, Thanks for bringing this to our attention. The issue is we're starting to move from Python 2 to Python 3 and this appears to be another teething problem. In Python 2 the `i/4` at line 270 will floor to an int. In Python3 it will return a float (obviously not a valid index for a list). I'll look into fixing this on our develop branch, but I believe this can be fixed by changing this to `i//4`. I.e.: ` mem_ctrls[i].port = xbar[i//4].master`. Kind regards, Bobby -- Dr. Bobby R.

[gem5-users] Re: write if-else statement in slicc transition code blocks.
Hello,
If you want to trigger two different transitions based on different inputs,
this should always go in the in_port definition. For instance, see
http://www.gem5.org/documentation/learning_gem5/part3/cache-in-ports/. You
can base this on the message information by using peek() on the buffer. If
you want to trigger based on the cache state, you should make sure the
state you need is stored in the TBE or cache block as a "State". Then, the
transition tagged with that state as a starting state will be triggered.
It's best practice to never use if statements except in in_ports. Remember,
you're describing a state machine, not writing imperative code. SLICC is
more like verilog than it is C/C++.
