How to Emulate cuBB by using RU Emulator & TestMAC

Accelerated Computing Aerial Forum

Hello, my name is Seungwoo Han, and I am a member of the RTCL Lab at DGIST univ.

Currently, our lab is conducting OpenRAN research using the GH200.
We have already purchased the GH200 and completed its setup.

At this stage, we would like to perform emulation using TestMAC and an RU Emulator.
From the link below, we learned that a Dell R750 server equipped with BlueField is required for the RU Emulator. However, we have found that it is currently not possible to purchase Dell or Gigabyte servers in our country.

Therefore, we would like to find a way to perform RU emulation without using the Dell R750 server.
Our questions are as follows:

  1. Is it possible to perform emulation without using the Dell R750 (i.e., excluding Dell and Gigabyte servers)?

  2. If so, what are the exact hardware requirements? (For example, is having only a BlueField-3 sufficient?)

  3. Based on the hardware specifications in question 2, what is the required setup procedure for running the emulation?

We would greatly appreciate your assistance on this matter.
If you need any additional information, please feel free to contact me at hswek@dgist.ac.kr.

Thank you.

Hi @qkenrdhkdwk1,

You can use the scripts here to configure your system.

Yes, it is possible to run a test using a single server. You need to connect two ports of the BF3 NIC with a physical loop-back connection.

In the test scripts, you can use the following commands to indicate your connection type:

./testBenches/phase4_test_scripts/setup1_DU.sh --ru-host-type=_LOOPBACK --du-eth0=aerial02
./testBenches/phase4_test_scripts/setup2_RU.sh --ru-eth0=aerial03

Here, aerial02 and aerial03 refer to the DU and the RU interfaces, respectively. You can replace them according to your system configuration if necessary (e.g. with aerial00 and aerial01)

Please note that you may not reach the full system capacity since the RU emulator will run on the same system as the DU.

Thank you.

Hi @qkenrdhkdwk1

on your GH200 server, what NIC cards do you have?

Hi!

Our GH200 is equipped with one ConnectX-7 and one BlueField-3 as NICs.
