Hi all,
With Nilay’s recent improvements to Ruby I would like to understand if there is
any point in still having the RubyMemoryControl, or if we should just clean
things up a bit and remove it. I would think the best way forward is to clean
up the integration of Ruby and classic and ensure

build/ARM/tests/opt/long/se/40.perlbmk/arm/linux/o3-timing. I updated the
stats for these, not sure why zizzer is complaining. I think
realview-minor-dual failed due to some issue with its implementation. I
Hi Nilay,
Thanks for the clarification. I believe the RubyMemoryController is
completely Pareto dominated by the vanilla DRAMCtrl module, but if there
is any specific feature/setting missing I would be keen to know.
If possible I would like to make sure we use the same controller as a
default
Hi Nilay,
There should be no uninitialized values, at least based on UBSan, valgrind
and static analysis.
If a regression is indeed failing and the behavior is repeatable, could
you try the aforementioned options?
Thanks,

Hi Joel,
I am happy to spend the 5 minutes creating a GDDR5 configuration. Do you
have any specific data sheet you would like to capture?

Hi Andreas,
Sure thing. We try to closely replicate the parameters used in GPGPU-Sim
v3.2.2, which are specified in the Hynix datasheet here:
http://www.hynix.com/datasheet/pdf/graphics/H5GQ1H24AFR(Rev1.0).pdf.
Here are relevant excerpts from the GPGPU-Sim GTX480 config file
(attached):

Hi Joel,
Thanks. I really do not understand the return queue argument. Why on earth
would you need such a large return queue? Surely the agent making the
requests (the GPU in this case) should have allocated space for the
response, no?
Concerning the configuration, what is the assumed clock

Good question. I believe that buffer is just to get
