Hi,
I'm running into a deadlock problem for running Ruby for 32 cores or more.
The error message is as follows:
build/ALPHA_FS_MOESI_CMP_directory/m5.opt -d ruby_opt/ --trace-flags=Exec
configs/example/ruby_fs.py -b fft_64t_base -n 32
warn: Prefetch instrutions is Alpha do not do anything
For more
This problem may be related to my earlier post i sent today about Debugging
Ruby Deadlocks, but when adding the RubyQueue traceflag for 32 cores you
get this error:
build/ALPHA_FS_MOESI_CMP_directory/m5.opt -d ruby_opt/
--trace-flags=RubyQueue configs/example/ruby_fs.py -b fft_64t_base -n 1
...
It is working fine for me.
./build/X86_SE_MESI_CMP_directory/m5.fast
./configs/example/ruby_random_test.py -n 4 -l 1

Hi Korey,
A few comments:
- The difference in time is because the sequencer prints out the RubyCycle
count for the issue time while the tick count is the global curTick value. Now
that Ruby uses DPRINTFs, I think it makes sense to move all those ruby print
outs to ticks. I actually have
Yes, that's bizarre, since I was using the same tip, no patches applied.
Don't know what to tell you Arka...since you and Nilay are both in
Wisconsin maybe you can look at the differences in your setups, because so
far it seems like it's just you :P.

Hey Brad,
Thanks for the suggestions.
The Protocol Trace flag looks really promising. It'd be very nice to get
everything in , but I'm just a little worried about tweaking that if these
RubyCycle counts are used for anything other than annotation. I'll take a
strong look at starting to get that
I think many of us have noticed that scons sometimes rebuilds things
when it's not necessary. Here's one clue:
% scons build/ALPHA_SE/m5.debug
scons: Reading SConscript files ...
[...]
scons: done building targets.
% scons --debug=explain build/ALPHA_SE/m5.debug
scons: Reading SConscript files
