copyResultsFromDeviceToHost Error

Accelerated Computing Aerial Forum

So I am generating a simulation of about 1000 Ues and 11 RUs, and I am able to generate the UEs fine and start the mobility, but when i get to 99% completed it throws the following error:

2025-03-26 19:15:06 [867,856ms] [Error] [aodt.common.utils] copyResultsFromDeviceToHost returned an error (-2127953920)

any advise? I am trying to find the code this is referencing so i can dig into it but i cannot locate it.

  1. What is the hardware configuration?
  2. How many samples do you run this for?
  3. What is the number of antennas?
  4. Can you reduce the number of UEs and RUs?
  5. Can you disable the generation of the wideband CFRS? You can do that via the namesake parameter in the ‘scenario’

My configuration is the Microsoft Azure specification from the installation documentation as i deployed it by following those instructions.

I actually did find out that the UE spawn zone was trying to spawn UEs outside the bounds so it was finding no logical path. I fixed this issue actually after figuring it out

@michael.chiaramonte
“copyResultsFromDeviceToHost returned an error” ← this is unlikely due to spawn zone. The error most likely comes from the size of simulation. You should be able to fit 10RUs and 100 UEs with a 4TRX.

The spawn zone will not create UEs outsize of the spawn zone. Did you have a manual UE and a span zone? Can you share the map with the spawn zone?

I was able to fix that issue it was the size of the simulation making it crash or have that error.
