Running-SPEC-CPU-Benchmarks-in-Full-System-Mode-with-gem5art

Running SPEC CPU Benchmarks in Full System Mode with gem5art SPEC CPU 2017 benchmarks are essential evaluations for assessing computer processor performance. The gem5art tool simplifies the execution of these benchmarks within the gem5 simulator by providing a user-friendly interface for setup, execution, and result analysis. gem5art streamlines the simulation process and offers features that enhance result interpretation Concurrently, the gem5-resources project offers a comprehensive set of resources—like disk images, Linux kernels, and gem5 configurations—tailored explicitly for executing SPEC CPU 2017 benchmarks in the gem5 environment. These resources, specialized for improved benchmark accuracy, facilitate an efficient start for running these benchmarks The process for running SPEC CPU 2006 benchmarks largely mirrors that of SPEC CPU 2017, differing only in the use of the 'src/spec-2006' folder from gem5-resources instead of 'src/spec- 2017'. Below are the steps taken to conduct the experiment: Step 1: Acquiring gem5-resources and setting up the Experiment Folder: 1. git clone https://gem5.googlesource.com/public/gem5-resources 2. cd gem5-resources 3. git checkout 1fe56ffc94005b7fa0ae5634c6edc5e2cb0b7357 Step 2: Initialize git. 1. cd src/spec-2017 2. git init 3. git remote add origin https://remote-address/spec- experiment.git Step3: Document the root folder experiments_repo = Artifact.registerArtifact ( command = ''' git clone https://gem5.googlesource.com/public/gem5-resources cd gem5-resources git checkout 1fe56ffc94005b7fa0ae5634c6edc5e2cb0b7357 cd src/spec-2017

To set up Gem5 on Ubuntu, you'll need essential dependencies like m4, Python, SCons, GCC, Git, and others. Administrative privileges are necessary when executing SCons commands. These packages can either be installed directly or managed through a Python virtual environment. Even when I used an ubuntu based environment I got issues Like: Conclusion: Based on my experience, it's essential for Gem5 to expand its testing beyond specific operating systems. Attempting to run Gem5 on a macOS system proved challenging. Despite clear instructions in the documentation, I encountered difficulties when Gem5 failed to execute correctly. To enhance user experience, Gem5 should provide more comprehensive documentation regarding its dependencies and offer a section dedicated to addressing frequently encountered errors. This would significantly assist users in troubleshooting issues that arise during installation or execution.
