Hi, all
I just began to use GEM5 and was in trouble for the following issue.
My objective is to configure directory-based cache coherence protocol with
ALPHA and full system mode.
After googling(isca_pres_2011.pdf), I tried to use the following two
commands.
1. scons build/ALPHA/gem5.opt PROTOCOL=MOESI_CMP_directory
2. build/ALPHA/gem5.opt configs/example/ruby_fs.py --cpu-type=timing
--num-cpus=8 --l1i_size=32kB --l1d_size=32kB --l2_size=8MB --num-l2caches=8
--topology=Crossbar
However, in building the system through the 2nd command, I got the
following error.
optparse.OptionValueError: option --cpu-type: invalid choice: 'timing'
(choose from )
For me, 'timing' seems to be one of proper option values for --cpu-type,
but the error saying invalid choice appeared.
I wanted to use the option value, 'timing', because the combination of
Timing Simple CPU model and Ruby is fully
supported under ALPHA, according to the searched
document(isca_pres_2011.pdf)
Is there any problem problem in the command or any other suggestion?
Thanks.
