The coherent memory interconnects between nodes is typically what makes supercomputers different than just a bunch of consumer hardware. It allows different types of programming or at least makes them easier.
- jabl 4y agoIt's a very fast, very low latency network fabric. But it's not coherent in the sense of cache coherent multiprocessors, and it doesn't offer shared memory style programming where you'd just load/store to addresses that happen to be mapped to another compute node somewhere in the system.
- l33t2328 4y agoI thought DMI allowed for exactly those kinds of load/store operations
