Disable individual links of NVLink 2.0


I’m interested in measuring the performance impact of interconnect bandwidth on my application. Specifically, I’d like to reduce the bandwidth step-by-step.

Is it possible to disable the links of NVLink individually, i.e., run with 1 link instead of 3? Or perhaps control the link speed, i.e., run the links at 12 GB/s instead of 25 GB/s?

It’s not possible.
