> For many years, RDMA NICs could cache the state for only a few hundred connections; if the number of active connections exceeded the cache size, information had to be shuffled between host memory and the NIC, with a considerable loss in performance.

A massively parallel task? Sounds like something doable with GPGPU.

Now the information has to be shuffled between the NIC and host memory and the GPU.

Just plug ethernet cable into the graphics card, then you need to shuffle memory between GPGPU and the wire.
