This document includes instructions on how to create an Ubuntu 18.04 disk-image with PARSEC benchmark installed. The disk-image will be compatible with the gem5 simulator. It also demostrates how tosimulate the same using an example gem5 script with a pre-configured system. The script uses a pre-built disk-image.
This is how the
src/parsec-tests/ directory will look like if all the artifacts are created correctly.
parsec/ |___ gem5/ # gem5 folder | |___ disk-image/ | |___ build.sh # the script downloading packer binary and building the disk image | |___ shared/ | |___ parsec/ | |___ parsec-image/ | | |___ parsec # the disk image will be here | |___ parsec.json # the Packer script | |___ parsec-install.sh # the script to install PARSEC | |___ post-installation.sh # the script to install m5 | |___ runscript.sh # script to run each workload | |___ parsec-benchmark # the parsec benchmark suite | |___ README.md
In order to build the disk-image for PARSEC tests with gem5, build the m5 utility in
src/parsec-tests/ using the following:
git clone https://gem5.googlesource.com/public/gem5 cd gem5/util/m5 scons build/x86/out/m5
We use packer to create our disk-image. The instructions on how to install packer is shown below:
cd disk-image ./build.sh # the script downloading packer binary and building the disk image
In order to build the disk-image first the script needs to be validated. Run the following command to validate
./packer validate parsec/parsec.json
After the script has been successfuly validated you can create the disk-image by runnning:
./packer build parsec/parsec.json
You can find the disk-image in
An example script with a pre-configured system is available in the following directory within the gem5 repository:
The example script specifies a system with the following parameters:
KVMfor startup and
TIMINGfor ROI execution). There are 2 CPU cores, each clocked at 3 GHz.
MESI_Two_Levelcache with 32 kB L1I and L1D size, and, 256 kB L2 size. The L1 cache(s) has associativity of 8, and, the L2 cache has associativity 16. There are 2 L2 cache banks.
x86-parsec, the disk image created from following the instructions in this
The example script must be run with the
X86_MESI_Two_Level binary. To build:
git clone https://gem5.googlesource.com/public/gem5 cd gem5 scons build/X86/gem5.opt -j<proc>
Once compiled, you may use the example config file to run the PARSEC benchmark programs using the following command:
# In the gem5 directory build/X86/gem5.opt \ configs/example/gem5_library/x86-parsec-benchmarks.py \ --benchmark <benchmark_program> \ --size <size> \
Description of the two arguments, provided in the above command are:
x264. For more information on the workloads can be found at https://parsec.cs.princeton.edu/.
The working status of PARSEC runs for gem5-20 has been documented here.
