DriverError(CUDA_ERROR_ILLEGAL_ADDRESS, "an illegal memory access was encountered")
trafficstars
I am relatively new so I hope I am not just doing something very stupid :)
I am trying to adapt the quantized example for my use case. The inference code is pretty much the same as the example. In general, the code works and I am prompting 2 models on 2 separate GPUs in a loop. After N iterations (N is different every time but in range <100) I encounter the error below.
I am running quantized llama-3-8b-instruct from .gguf.
I would appreciate any tips on this topic if the error is on my side. Here is the access to the code.
NOTE: I'm running two A6000 GPUs. This is the nvcc version:

We see this backtrace repeat again because we see successive threads writing to successively higher addresses:

...though, given we're talking about threads here, not always in a linear order:
