Haven’t tried other than Infiniband, except a brief stint with OPA (which you certainly know about), which was also fine.

<div>I have a sense that not that many users are taking advantage of the Infiniband performance, but I don’t know how close the performance is.</div>

Here's a good topic for discussion: What are your thoughts on Ethernet vs. InfiniBand? Can UltraEthernet compete with/surpass IB, or is IB still the standard for non-proprietary (Slingshot, Tofu, etc.) networking for HPC? Discuss!<br>
