This chapter describes how to install the required kernel, driver, and tools on the host. This is a one-time installation and can be skipped if the system has been configured already.
In the following sequence of steps, the target host is the Aerial Devkit.
Depending on the release, tools that are installed in this section may need to be upgraded in the Installing and Upgrading cuBB SDK section.
After everything is installed and updated, refer to the cuBB Quick Start Guide on how to use the cuBB SDK.
Install the GPU card and CX6-DX NIC.
Connect the CX6-DX port 0 on both servers using a 100GbE cable.
Connect the Internet port to the local network.
Change the following system BIOS settings to improve network performance:
Set the Power Policy to Best Performance.
Set the Power Policy SpeedStep (Pstates) option to “Disabled”.
Disable HyperThreading. Ensure you have performed Step 1 above before doing this step.
Save the BIOS settings, and then reboot the system.
After installing Ubuntu 22.04 Server, verify the following:
The system time is correct, to avoid apt update error. If not, see How to fix system time.
The LVM volume uses the whole disk space. If not, see How to resize LVM volume.
Check that the GPU and NIC are detected by the OS:
Use the following commands to determine whether the GPU and NIC are detected by the OS:
$ lspci |grep -i nvidia # If the system has A100 40G GPU installed b6:00.0 3D controller: NVIDIA Corporation Device 20f1 (rev a1) # If the system has A100 80G GPU installed b6:00.0 3D controller: NVIDIA Corporation Device 20b5 (rev a1) # If the system has A100X GPU installed bb:00.0 3D controller: NVIDIA Corporation Device 20b8 (rev a1) $ lspci |grep -i mellanox b5:00.0 Ethernet controller: Mellanox Technologies MT2892 Family [ConnectX-6 Dx] b5:00.1 Ethernet controller: Mellanox Technologies MT2892 Family [ConnectX-6 Dx]
Run the following command to verify that the BIOS setting update took effect:
$ lscpu
Verify that hyperthreading is disabled:
# Thread(s) per core: 1
The following installation steps need an Internet connection. Ensure that you have the proper netplan config for your local network.
The network interface names could change after reboot. To ensure persistent network interface names after reboot, create a persistent net link files under /etc/systemd/network, one for each interface.
To find the MAC addresses of the CX6-DX NIC, run the ip a command, then look for the MAC address that
starts with “b8:ce:f6”:
$ ip a

Create files at /etc/systemd/network/11-persistent-net.link and /etc/systemd/network/12-persistent-net.link with the desired name for the interface and the MAC address found in the previous step.
$ sudo nano /etc/systemd/network/11-persistent-net.link
# Update the MAC address to match the converged accelerator port 0 MAC address
[Match]
MACAddress=b8:ce:f6:xx:xx:xx
[Link]
Name=ens6f0
$ sudo nano /etc/systemd/network/12-persistent-net.link
# Update the MAC address to match the converged accelerator port 1 MAC address
[Match]
MACAddress=b8:ce:f6:yy:yy:yy
[Link]
Name=ens6f1
To apply the change:
$ sudo netplan apply
Edit the /etc/apt/apt.conf.d/20auto-upgrades system file, and change the “1” to “0” for both lines.
This prevents the installed version of the low latency kernel from being accidentally changed with a
subsequent software upgrade.
$ sudo nano /etc/apt/apt.conf.d/20auto-upgrades
APT::Periodic::Update-Package-Lists "0";
APT::Periodic::Unattended-Upgrade "0";
If the low latency kernel is not installed, you must remove the old kernels and keep only the latest generic kernel. Enter the following command to list the installed kernels:
$ dpkg --list | grep -i 'linux-image' | awk '/ii/{ print $2}'
# To remove old kernel
$ sudo apt-get purge linux-image-<old kernel version>
$ sudo apt-get autoremove
Install the low-latency kernel with the specific version listed in the release manifest.
$ sudo apt-get update
$ sudo apt-get install -y linux-image-5.15.0-1042-nvidia-lowlatency
Update the GRUB to change the default boot kernel:
# Update grub to change the default boot kernel
$ sudo sed -i 's/^GRUB_DEFAULT=.*/GRUB_DEFAULT="Advanced options for Ubuntu>Ubuntu, with Linux 5.15.0-1042-nvidia-lowlatency"/' /etc/default/grub
To set kernel command-line parameters, edit the GRUB_CMDLINE_LINUX_DEFAULT parameter in the GRUB
file /etc/default/grub and append or update the parameters described below. The following kernel parameters
are optimized for Aerial DevKit with 24 cores Xeon Gold 6240R and 96GB memory.
To automatically append the GRUB file with these changes, enter this command:
$ sudo sed -i 's/^GRUB_CMDLINE_LINUX_DEFAULT="[^"]*/& default_hugepagesz=1G hugepagesz=1G hugepages=16 tsc=reliable clocksource=tsc intel_idle.max_cstate=0 mce=ignore_ce processor.max_cstate=0 intel_pstate=disable audit=0 idle=poll isolcpus=2-21 nohz_full=2-21 rcu_nocbs=2-21 rcu_nocb_poll nosoftlockup iommu=off intel_iommu=off irqaffinity=0-1,22-23/' /etc/default/grub
The CPU-cores-related parameters need to be adjusted depending on the number of CPU cores
on the system. In the example above, the “2-21” value represents CPU core numbers 2 to 21; you may
need to adjust this parameter depending on the HW configuration. By default,only one DPDK thread is
used. The isolated CPUs are used by the entire cuBB software stack. Use the nproc --all command
to see how many cores are available. Do not use core numbers that are beyond the number of available
cores.
These instructions are specific to Ubuntu 22.04 with a 5.15 low-latency kernel provided by Canonical. Make sure the kernel commands provided here are suitable for your OS and kernel versions and revise these settings to match your system if necessary.
$ sudo update-grub
$ sudo reboot
After rebooting, enter the following command to verify that the system has booted into the low-latency kernel:
$ uname -r
5.15.0-1042-nvidia-lowlatency
Enter this command to verify that the kernel command-line parameters are configured properly:
$ cat /proc/cmdline

Run PHC2SYS as service:
PHC2SYS is used to synchronize the system clock to the PTP hardware clock (PHC) on the NIC. The following are the two examples of PHC2SYS configurations.
Example 1: Specify the network interface used for PTP and system clock as the slave clock. This is the default mode when the devkit is configured as a gNB or RU emulator to run cuBB test.
# If more than one instance is already running, kill the existing # PHC2SYS sessions. # Command used can be found in /lib/systemd/system/phc2sys.service # Update the ExecStart line to the following $ cat <<EOF | sudo tee /lib/systemd/system/phc2sys.service [Unit] Description=Synchronize system clock or PTP hardware clock (PHC) Documentation=man:phc2sys Requires=ptp4l.service After=ptp4l.service [Service] Restart=always RestartSec=5s Type=simple ExecStart=/bin/sh -c "taskset -c 21 /usr/sbin/phc2sys -s /dev/ptp$(ethtool -T ens6f0 | grep PTP | awk '{print $4}') -c CLOCK_REALTIME -n 24 -O 0 -R 256 -u 256" [Install] WantedBy=multi-user.target EOF
Example 2: Synchronize time automatically according to the current ptp4l state and synchronize the system clock to the remote master. This configuration is usually performed when the devkit is configured as a gNB to run E2E test in the LLS-C3 topology.
# If more than one instance is already running, kill the existing # PHC2SYS sessions. # Command used can be found in /lib/systemd/system/phc2sys.service # Update the ExecStart line to the following, the -a option will use the same interface as ptp4l and -r will synchronize the system clock $ cat <<EOF | sudo tee /lib/systemd/system/phc2sys.service [Unit] Description=Synchronize system clock or PTP hardware clock (PHC) Documentation=man:phc2sys Requires=ptp4l.service After=ptp4l.service [Service] Restart=always RestartSec=5s Type=simple ExecStart=/usr/sbin/phc2sys -a -r -n 24 -R 256 -u 256 [Install] WantedBy=multi-user.target EOF
After the PHC2SYS config file is changed, run the following:
$ sudo systemctl daemon-reload
$ sudo systemctl restart phc2sys.service
# Set to start automatically on reboot
$ sudo systemctl enable phc2sys.service
# check that the service is active and has converged to a low rms value (<30) and that the correct NIC has been selected (ens6f0):

Verify that the system clock is synchronized:
$ timedatectl
Local time: Thu 2022-02-03 22:30:58 UTC
Universal time: Thu 2022-02-03 22:30:58 UTC
RTC time: Thu 2022-02-03 22:30:58
Time zone: Etc/UTC (UTC, +0000)
System clock synchronized: yes
NTP service: inactive
RTC in local TZ: no
Create the directory /usr/local/bin and create the /usr/local/bin/nvidia.sh file to run the commands with every reboot.
The network interfaces here match those used above - ens6f0 and ens6f1.
Also, the command for “nvidia-smi lgc” expects just one GPU device (-i 0). This needs to be modified if the system uses more than one GPU.
$ cat <<"EOF" | sudo tee /usr/local/bin/nvidia.sh
#!/bin/bash
mst start
ifconfig ens6f0 up
ifconfig ens6f1 up
ethtool --set-priv-flags ens6f0 tx_port_ts on
ethtool --set-priv-flags ens6f1 tx_port_ts on
ethtool -A ens6f0 rx off tx off
ethtool -A ens6f1 rx off tx off
sysctl -w kernel.numa_balancing=0
nvidia-smi -pm 1
nvidia-smi -i 0 -lgc $(nvidia-smi -i 0 --query-supported-clocks=graphics --format=csv,noheader,nounits | sort -h | tail -n 1)
nvidia-smi -mig 0
echo -1 > /proc/sys/kernel/sched_rt_runtime_us
EOF
Create a system service file to be loaded after network interfaces are up.
$ cat <<EOF | sudo tee /lib/systemd/system/nvidia.service
[Unit]
After=network.target
[Service]
ExecStart=/usr/local/bin/nvidia.sh
[Install]
WantedBy=default.target
EOF
Then set the file permissions, reload the systemd daemon, enable the service, restart the service when installing the first time, and check status
sudo chmod 744 /usr/local/bin/nvidia.sh
sudo chmod 664 /lib/systemd/system/nvidia.service
sudo systemctl daemon-reload
sudo systemctl enable nvidia.service
sudo systemctl restart nvidia.service
systemctl status nvidia.service
The output of the last command should look like this:
aerial@devkit:~$ systemctl status nvidia.service

This step is optional. Matlab is not required to generate TV files if using Aerial Python mcore module. See Generating TV and Launch Pattern Files section in cuBB Quick Start Guide.
Refer to https://www.mathworks.com/downloads/ for downloading and installing Matlab. Follow the established IT process for the license and installation at your site.
Matlab is used to run the test-vector generator script. This can be run on any machine that has a graphical display and a graphical UI capable operating system that Matlab supports. The generated test-vector files can then be copied to the cuBB server.
If you would like to run the test-vector generator Matlab script on the same Ubuntu server machine
that runs cuBB, then Matlab should be run in console mode matlab -nosplash -nodesktop.
The following Matlab components are required:
Matlab 2020b or later
Matlab licenses:
MATLAB
Communications Toolbox
DSP System Toolbox
Signal Processing Toolbox
Fixed-Point Designer (optional)
Call half function to accelerate testing/simulation
Can be disabled by setting SimCtrl.fp16AlgoSel = 1
Parallel Computing Toolbox (optional)
Accelerate testing/simulation automatically
5G Toolbox
Not required for TV generation (can be disabled by setting Chan.use5Gtoolbox = 0 in /nr_matlab/config/cfgChan.m)
Required for waveform compliance test and performance simulation
