architecture. In a few years we'll have, say, 1024 processors on a
chip, and something new will be required to manage them. It will be a
thousand times simpler and more reliable than Windows.
I think that the number of virtual cores will grow faster than the
number fo real cores. With extra register banks and a bit of clever
design, a single ALU can look like two slightly slower ones.
I expect to see multicore machines with less actual floating point
ALUs than actual integer ALUs.
Yup. Low-horsepower tasks can just be a thread on a multithread core,
and many little tasks don't need a dedicated floating-point unit.
My point/fantasy is that OS design should change radically if many,
many real or virtual CPUs are available. One CPU would be the manager,
and every task, process, or driver could have its own, totally
confined and protected, CPU, and there would be no context switching
ever, and few interrupts in fact.
