Hi Bobby, I’m trying to modify my gem5-X setup to add the NPB performance tests.
My gem5-X setup doesn’t have a configs/example/gem5_library. I believe the github repo for the gem5-X build didn’t add the gem5_library directory and files. I could use the gem5 setup from the NPB but then I’ll not be able to do architectural exploration with gem5-X. I would prefer to stick to gem5-X and add on the NPR tests. This is our cmd-line to build the gem5-X `./build/ARM/gem5.fast --remote-gdb-port=0 -d log_dir configs/example/fs.py --cpu-clock=1GHz --kernel=vmlinux --machine-type=VExpress_GEM5_V1 --dtb-file=/home/dfong/work/ext_ips/gem5-X/system/arm/dt/armv8_gem5_v1_1cpu.dtb -n 1 --disk-image=gem5_ubuntu16.img --caches --l2cache --l1i_size=32kB --l1d_size=32kB --l2_size=1MB --l2_assoc=2 --mem-type=DDR4_2400_4x16 --mem-ranks=4 --mem-size=4GB --sys-clock=1600MHz` What do you recommend I should do ?

It seems the gem5art tutorial on the website has become a bit outdated. We've updated gem5-resources in the last release and clearly this has broken some links. I'll make sure updating this is prioritized. I have two ways you can run NPB. The first is quite simple and is basically what Jason said, there's a script in `configs/example/gem5_library/x86-npb-benchmarks.py` which you can execute with gem5 and run NPB. This should work: `./build/X86/gem5.opt configs/example/gem5_library/x86-npb-benchmarks.py --benchmark ep --size A` (warning, this script assumes you're running gem5 on an X86 host with KVM). This approach is using our gem5 stdlib, a tutorial to which can be found here: https://www.gem5.org/documentation/gem5-stdlib/overview<https://urldefense.proofpoint.com/v2/url?u=https-3A__www.gem5.org_documentation_gem5-2Dstdlib_overview&d=DwMFaQ&c=euGZstcaTDllvimEN8b7jXrwqOf-v5A_CdpgnVfiiMM&r=OkH-8nM02VdNPRt_miVO36vI9580zW1SgNQ4MzWRfqc&m=eSlpqdCMZ0MQaU6uWmL6HLshxvwDW_rT1yOkyrY4pJM&s=XrODO-sPqMN8yjZ4qLcyRP0EbgeB1S1OBBi8JNt8kZc&e=> The second way is to checkout the gem5-resources repo to the state it was at the last release. The tag you want is v21.1.0.2, https://gem5.googlesource.com/public/gem5-resources/+/refs/tags/v21.1.0.2/<https://urldefense.proofpoint.com/v2/url?u=https-3A__gem5.googlesource.com_public_gem5-2Dresources_-2B_refs_tags_v21.1.0.2_&d=DwMFaQ&c=euGZstcaTDllvimEN8b7jXrwqOf-v5A_CdpgnVfiiMM&r=OkH-8nM02VdNPRt_miVO36vI9580zW1SgNQ4MzWRfqc&m=eSlpqdCMZ0MQaU6uWmL6HLshxvwDW_rT1yOkyrY4pJM&s=f9_9A5mxEZUWXFac_JuBcUfXrqeK_ftZV6TlL4NPvF8&e=>. This should contain the configs (If you do this, i think it'd be best to checkout the gem5 repo to an earlier release as well). Kind regards, Bobby -- Dr. Bobby R.
