Do you have a prepared container image file?
Hello, TCCL currently only considers single-NIC systems, as it is specialized to find a single ring path. For the "No rank available" error, the number of spawned MPI processes seems too small. If the number of GPU in a system is 8, you need to spawn at least 19 (= 3 + 8 * 2) processes per node, on all 3 nodes.

Is there a fundamental reason multi-NIC systems are not supported?
Do you have any suggestion on where to start if I would like to extend it to support multi-NIC?
When I execute the program pathfinder, I get the error shown in the screenshot below. What is the reason for this? Thanks!![1](https://github.com/mcrl/tccl/assets/8925075/55eb56b4-1a4e-40f1-98da-4086545ffa0a)
