we have now university CUDA courses providing us students access to nvidia Kepler cards and mellanox connect-x3 cards with 40GBE ethernet switches.
As I am reading about the hardware, I am getting more interested beyond the course work (which is mainly about cuda programming bascis).
I do not really know if I am understanding all facets of gpudirect rdma. Is there any source for sample programs which do useful things?
What I am interested in is for example a GPU network communication sample like the following:
Connect-x3 card #1 receives a packet copies it to Tesla card
Tesla card does a ROT13 on the string in tcp payload … just an example
Tesla card decides the ethernet packet with rotated payload should be sent to another server, generates the ethernet packet and sends it through Connect-x3 card #2
So you see what I am interested in is probably a sort of basic gpu accelerated massive parallel network accelerator. I think of for example a SSL accelerator sitting between network routers and the host doing all SSL encryption for it. But I am at moment only interested if and how it is possible to this basic work (e.g. receive packet in gpu, edit packet, send packet to another host)
