Question about Data Lake support with RU Emulator + cuphycontroller + TestMAC

Accelerated Computing Aerial Forum

Hello,

I am currently running the RU Emulator + cuphycontroller + TestMAC setup on a GH200 server.

I would like to ask whether Data Lake is expected to work properly in this emulation-level environment as well.
My main interest is only in collecting or inspecting the UL_TTI.request FAPI messages.

I am a bit concerned that Data Lake might try to collect RU-side data, and since I am using the RU Emulator instead of a real O-RU, this could potentially cause issues.

Could you please confirm whether Data Lake is supported in this type of RU Emulator + TestMAC setup, especially if I only want to access UL_TTI.request messages?

The actual configuration files I am using are:

  • cuphycontroller_nrSim_SCF_CG1_90063.yaml

  • l2_adapter_config_nrSim_SCF_mu_1_90063.yaml

Thank you.

Hi @jinwoomoon ,

Data Lake is designed to operate at the cuphycontroller level, and the FAPI message data (including UL_TTI.request) is captured inside cuphycontroller after the PUSCH pipeline runs. This means your RU Emulator setup should not be a problem for this specific use case.

If you want to capture only FAPI messages, you can do it by enabling the NVIPC PCAP log. The Wireshark dissector to decode the PCAP file is available on NGC.

Thank you.
