My XP, not doing much right now, claims to be running 31 processes.
Add in maybe another 30 device drivers, tcp/ip stacks, and file
managers, and it would keep a 64-core cpu mostly employed.

Yes, but would it run faster?

Since it wouldn't spend a lot of time context switching, and since it
wouldn't crash and require reboots, and since it wouldn't leak memory
and require reboots, and since it wouldn't trash virtual page files,
and since everything would keep running (as opposed to everything
pausing for 10 seconds now and then), yes, for me I'd come out ahead.

You really should investigate *why* your PCs are so unreliable rather
than blathering on about how the world would be all sweetness and light
if only Intel would make a 256 core CPU.

XP isn't bad, especially to people whose standards were lowered by '95
and '98. To people who used to run DEC timeshare systems, or who do
hard realtime stuff that may not have bugs, it's still pretty bad.

Blathering? Do you think that computer architectures are perfected,
and will never change? Do you think that all the multicore CPU's being
introduced will only be used to make things more complex and less
reliable? Sure, pile OS virtualization on top of a heap of the
gigabyte dogs we're running now, and use the extra cpu's to run
multiple threads of Adobe products.

On the whole, this newsgroup should be renamed
sci.electronics.tradition. It's practically impossible to get anyone
to riff on ideas; these guys mostly want to defend current and
comfortable practice. I shouldn't complain... I make a lot of money
taking business away from people who refuse to think.

I suppose I won't bother to post my BGA transformer idea. Thousands of
man-hours would be expended all over the world inventing reasons why
it wouldn't work.
