Issues Running Aerial cuBB Test Bench F08 Without BlueField3 DPU

Accelerated Computing Aerial Forum

Hi，

We are trying to run Aerial cuBB test bench in our system, but meet some problems. We hope can get help.

Hardareware: X86 Server( Intel Xeon W-3175X CPU) + A100 GPU + Mellanox MCX653105A-HDAT VPI adapter card

Software: Aerial CUDA-Accelerated RAN Release 24-3

When we try to run the cuBB End-to-End test bench F08, the cuPhyCtroller quits because of DOCA service failure.

We thinks the reason is no BlueField3 DPU in our system.

So, our quetions are:

  1. if that’s possible to run the End-to-End test bench F08 without BlueField3 DPU? Can we use the CX6 adapter card(not in Dx serials) instead of BF3?

  2. The user guide says, the 64TR is supported in this version. But we only find testcase for 4T4R/16T16R. Do PUSCH/PDSCH 64TR cases are supported in this version?

Thanks for your help!

Hi @fltang ,

BF3 is needed for Aerial.

  1. The user guide says, the 64TR is supported in this version. But we only find testcase for 4T4R/16T16R. Do PUSCH/PDSCH 64TR cases are supported in this version?

Please see 5GModel/nr_matlab/test/genLaunchPatternFile.m. You can find 64TR test cases starting with TC 606.

Please note that these test cases are defined as nrSim test cases.
We plan to have F08 patterns for 64TR on the next release.

Thank you.

Why BF3 is necessary? Seems，it’s just used as a network adaptor to send data to GPU. The ARM sub system doesn’t work. What’s the difference between BF3 and CX6 network adaptor? It’s not easy for us to have a BF3.

Hi @fltang
For E2E including cuBB E2E, PTP synchronization is needed. We have verified the E2E with BF3, CX6DX but not with CX6.

Thanks!
