Hi,

they can comunicate to each other over the PCIe bus.

Since the DE4 has a 4x PCIe 2.0 interface, you can get 4x 5 Gbit/s full duplex for each DE4, assuming the motherboard supports it.

It's also possible to use the HSMC connector. You'll need to find or design a cable or PCB with suitable pinouts to interconnect two DE4s.

Maybe SAMTEC has suitable assemblies.

In terms of software and design, there's no support for managing more than one FGPA.

Of course, Altera provides multiple comunication blocks (PCIe, SeriaLite, ALT_LVDS, etc) that you can and should use but beyond that, you're on your own.
