Generating TV and Launch Pattern Files
Since cuBB 22-2.2 release, the test vectors are not included in the SDK. The developer needs to generate the TV files first before running cuPHY examples or cuBB end-to-end test.
No Matlab license required to generate TV files using Aerial Python mcore module. The cuBB Container already has aerial_mcore installed. To generate the TV files, run the following commands inside the Aerial container.
The TV generation may take few hours on the devkit with current isocpus parameter setting in kernel command line. Please also ensure the host has sufficient space to contain 144GB of TV files.
cd ${cuBB_SDK}/5GModel/aerial_mcore/examples
source ../scripts/setup.sh
export REGRESSION_MODE=1
time python3 ./example_5GModel_regression.py allChannels
echo $?
ls -alF GPU_test_input/
du -h GPU_test_input/
Example output is shown below. The “real” time takes less than one hour on a 24 cores x86 host. The “echo $?” shows the exit code of the process, which should be 0. A non-zero exit code indicates a failure.

To Generate the launch pattern for each test case using cubb_scripts:
cd $cuBB_SDK
cd cubb_scripts
python3 auto_lp.py -i ../5GModel/aerial_mcore/examples/GPU_test_input -t launch_pattern_nrSim.yaml
Then Copy the launch pattern and TV files to testVectors repo.
cd $cuBB_SDK
cp ./5GModel/aerial_mcore/examples/GPU_test_input/*h5 ./testVectors/.
cp ./5GModel/aerial_mcore/examples/GPU_test_input/launch_pattern* ./testVectors/.
To generate TV files using Matlab, run the following command in Matlab:
cd('nr_matlab'); startup; [nTC, errCnt] = runRegression({'TestVector'}, {'allChannels'}, 'compact', [0, 1] );
All the cuPHY TVs are generated and stored under nr_matlab/GPU_test_input.
Generate the launch pattern for each test case using cubb_scripts:
cd $cuBB_SDK
cd cubb_scripts
python3 auto_lp.py -i ../5GModel/nr_matlab/GPU_test_input -t launch_pattern_nrSim.yaml
Copy the launch pattern and TV files to testVectors repo.
cd $cuBB_SDK
cp ./5GModel/nr_matlab/GPU_test_input/TVnr_* ./testVectors/.
cp ./5GModel/nr_matlab/GPU_test_input/launch_pattern* ./testVectors/.
