alt Hacker NewsWhen cores start needing more than 9 bits to be represented and RAM is in terabytes, many of the old assumptions need to change. Schedulers need to be implemented in userspace, RAM needs to be allocated in GB, not in 4k, io needs to require less round-trips between kernel and user space and NICs need to do a lot more work before the data reaches the CPU.
Does it need to be the same OS? Most consumer device are in the low 16GB range for memory with some outliers in the 64 and 128 GB. 32 cores are still in the realm of specialized devices.
Yes, we’re not the one paying for Linux development, but its subsystems are so complicated for general purpose computing. Like fitting formula 1 car parts onto a camry.
