we built a end-end test platform using aerial-accelerated-ran as a gNB and many real UEs. when gNB and many ues ran, cuphy in aerial-accelerated-ran print the error“WRN UlPhyDriver04 0 phychannel.cpp:368 [SB-L1] [DRV.PHYCH] [/opt/nvidia/cuBB/cuPHY-CP/cuphydriver/src/common/phychannel.cpp:368] cuda failed with result1 an illegal memory access was encountered” after the 161st ue accessed to gNB. Then L1 in aerial-accelerated-ran exited. What is happed on the error printed? how should we do to fix the error? Thanks a lot

Hi @harine_wind ,

Can you please provide the following:

  • Build flags you used,
  • Full phy.log
  • Yaml configuration files

Do you see print of the backtrace when the cuphycontroller stops? This should also been captured in the phy.log or on the console logs.

Thank you.

Hi @harine_wind

additional info needed… is it on aerial-testbed with OAI L2+ stack or a different non-opensource L2+ stack?

Thanks.
