Generating TV and Launch Pattern Files
Since the cuBB 22-2.2 release, the test vectors are not included in the SDK. You must generate the TV files before running cuPHY examples or cuBB end-to-end test.
TV generation is NOT supported on ARM because Matlab Compiler SDK doesn’t support it yet.
No Matlab license is required to generate TV files using Aerial Python mcore module. The cuBB container already has aerial_mcore installed.
To generate the test vectors required for end-to-end testing:
Run the following inside the Aerial container. It completes in less than a minute.
cd ${cuBB_SDK}/5GModel/aerial_mcore source scripts/setup.sh ./scripts/gen_e2e_ota_tvs.sh ls -lh GPU_test_input/ cp GPU_test_input/* ${cuBB_SDK}/testVectors/
Example output of the above:
The cuPhyChEstCoeffs.h5 file can be found in the /opt/nvidia/cuBB/testVectors directory of both the x86 and ARM containers.
aerial@c_aerial_aerial:/opt/nvidia/cuBB/5GModel/aerial_mcore$ source ./scripts/setup.sh [Aerial Python]aerial@c_aerial_aerial:/opt/nvidia/cuBB/5GModel/aerial_mcore$ ./scripts/gen_e2e_ota_tvs.sh Finished genCuPhyChEstCoeffs Elapsed time: 1.166473150253296 seconds [Aerial Python]aerial@c_aerial_aerial:/opt/nvidia/cuBB/5GModel/aerial_mcore$ ls -lh ../GPU_test_input/ -rw-rw-r– 1 aerial aerial 90K Oct 17 2023 ../cuPhyChEstCoeffs.h5
Copy the output to the testVectors folder.
To generate the all of TV files:
Run the following commands inside the Aerial container.
NoteThe TV generation may take a few hours on the devkit with the current isocpus parameter setting in the kernel command line. The host must have 64GB memory and 300GB available disk space. Hyperthreading must be enabled.
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
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/multi-cell/.
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/multi-cell/.
