Reinventing the Network Stack for Compute-Intensive Applications
8 dual port 100G NICs (available for a while)or 2 dual port 400 gigabit NICs (not yet available) would out-bandwidth the memory controller on an Epyc 7742; how are NICs such a bottleneck that they need to be increased 100x to keep up when DDR5 only doubles the bandwidth?<p>I forget what the bandwidth of CPU cache is but I'm guessing it's not 10 terabit/second either.
