I remember back in 2006, when multicore processors were rare and multisocket servers were expensive, how cool and powerful our OpenSSI cluster seemed to me as a junior sysadmin. Technology really went in a different direction, though, and we're buuilding new abstractions that bridge machines (e.g. kubernetes) instead of trying to extend unix across them.
- gnufx 7y agoI never used something like OpenSSI, but I'd be surprised if running over (presumably) Ethernet of the time worked well for an SSI compared with the "expensive" things like SGI Origin with fast links and hardware coherence. Solutions like that still exist, and there's the SCI standard. Current things like NVlink and CAPI seem to be rather in the same direction. I don't think Kubernetes is a fundamentally different abstraction to the (HPC) distributed resource managers that ran on shared- and distributed-memory systems of the time. (In that space MPI somewhat standardizes remote memory access and process spawning.)
