Deploy Qwen3.6-35B-A3B on DGX Spark

Use it with continue VSCode extension (once deployed)

Update the config.yaml file (usually located in ~/.continue/config.yaml):

"""DST I using FFT routines, Louis Thiry
Method 1 is 'naive' and used FFTs with twice bigger input signal.
Method 2 is more sophisticated and used iRFFT with half the input signal size.
The naive method 1 seems however to be more efficient, and JIT compilation is not key.
