My lambda quad 4x a6000 workstation has the GPUs setup to use NV4 and SLI/P2P options. This is reducing memory bandwidth between all 4 cards to 14GB/S. I need the cards to be connected solely via the nvlink bridge, so two pairs of linked cards at the highest shared memory speed possible.
How can I reconfigure the nvlinked cards so that they are no longer bonded 4way but operating as two separate nvlinked pairs?
Any update?
I have a blade system with 4 A6000.
What does the below output mean?
$ nvidia-smi nvlink -gt d -i 0,1,2,3
