For what it's worth, I've had rather more trouble with Ethernet than IB, especially given IB management facilities.

- detaro 5y agoIB always seemed like the kind of thing where you loose out a lot of comfort if you go with "old hardware sometimes found cheaply" and thus don't have vendor support, have to dig out drivers and tools from random sources, ...
- gnufx 5y agoObviously if you don't have driver support for the kernel you run, you can't use old stuff if you want to, but we had SDR IB running quite a long time without support. I don't have happy experience of HPC vendor support anyway, and unfortunately IB is now a Mellanox monoculture.
- Melatonic 5y agoProbably was also difficult because I had no experience working with it, no support, and there is not nearly as many online forum posts and articles written about common issues.
