Kimon is building a high-performance computing cluster that requires very high bandwidth and very low latency. What converged protocol is he most likely to select for this purpose?

Infiniband over Ethernet is commonly used for purposes like this, allowing direct memory access over Ethernet while providing high bandwidth and low latency. iSCSI is used for storage, VoIP is used for telephony, and Compute Express Link (CXL) is used for CPU to device and CPU to memory connections.
