A long time ago, when i was a kid, I had dream. It went like this:
I am waking up in the twenty-first century and start my computer.
After completing the boot sequence, I start top to find that my memory is
equal to total disk-capacity. What's more, there is no more swap.
Apps are executed inplace, as if already loaded.
Physical RAM is used to cache slower storage RAM, much the same as the CPU
cache RAM caches slower physical RAM.
I'm sure you can find a 4GB disk on ebay.
When I woke up, I was really looking forward for the new century.
Sadly, the current way of dealing with memory can at best only be described
as schizophrenic. Again the reason being, that we are still running in the
last-century mode.
Wouldn't it be nice to take advantage of todays 64bit archs and TB drives,
and run a more modern way of life w/o this memory/storage split personality?
Perhaps you'd be interested in single-level store architectures, where
no distinction is made between memory and storage. IBM uses it in one
(or maybe more) of their systems. A particularly interesting example is
