this is ... a NIC+FPGA which can execute code?
- spijdar 5y agoNo, it's offloading the code onto the processor on the NIC (which usually have several general purpose CPU cores). According to Wikipedia [0] it's not widely supported in hardware, but a few companies like Intel are "working on it". I guess the upshot is it gracefully "degrades" to running on the host CPU if on an unsupported NIC. [0] https://en.wikipedia.org/wiki/Express_Data_Path https://en.wikipedia.org/wiki/Express_Data_Path
- goombacloud 5y agoOffloading to the NIC is of course the fastest way but even doing it in the NIC driver (check if the NIC driver supports it or you have to use the slower generic fallback) you already have advantages similar to doing it with DPDK.
