I was wondering if this has been considered as a possible development
goal, now that the Intel multiprocessing hardware spec has been
standardized?

I know that MP (and specifically SMP) is sort of "trendy" these days
(vis. NT and OS/2 SMP), but the particular application for which I am
considering using Linux as a platform (dialin Internet host, web server,
fairly high volume) seems to me to be one for which SMP might give
good results--or at least make it easier to stave off the purchase of
a second machine.

So is this being considered, or at least batted around as a possibility?

Or has it already been hashed out and discarded?  I refuse to think that
it hasn't occured to anyone but me.

Mike.

For a web server which does spread easily between machines a pile of old
386SX's with 2-4Mb of RAM is very cost effective for the job.

For Linux doing none to smart (initially) SMP is being played with at the
concept level here (pending possible hardware donations). Some other people
'viper' are working on making the Linux kernel truely threaded but that is
a much bigger project.

I've just seen some new dual processor pentium systems in Computer
Shopper.  They look swell for the money, but there isn't a single OS
that can take advantage of them.  Anybody have any thoughts about how
hard it might be to make Linux one of the first OS's to take advantage
of these systems?

Not quite true... SCO MPX will work with many of them.  But it would still
be good to have Linux available......

WinNT works well on many multi-processor systems. IBM seems to be on the verge 
of releasing an SMP OS/2, as well. The problem, as I understand it, is that 
there is no firm multi-processor standard yet. The problem with working up an 
SMP or MPX version of Linux would be having to support all of the wierd 
variations of the architecture. Perhaps when manufacturers have a consistent 
standard, multi-processor Linux would be more feasable.

Is this opinion incorrect? Comments?

Linux should start supporting SMP now.
The commerical OS's have already, and they aren't anywhere near as 
good as UNIX or Linux.
We are supposed to be ahead of, not behind commercial operating systems.
Linux is a hacker's OS, and it should be developed as hacker's would, 
trying innovative approaches, not always trying to go with what is stable 
and standardized. If people want that, and Linux they can use the 
non-development kernels, but as for the rest of us, now is a good time 
to start broadening Linux's base. It already has made a powerful impact 
deep into the x86 world, so work in broadening its usefulneess is a good 
idea.

Linux reflects the hardware people posess - thats one thing thats good about
it - you can run it on a 4Mb 386SX, you can use old MFM drives , you can
use 360K floppies. You can run X on a herc card. Until a bunch of Linux
hackers have a multicpu pentium board and relevant documentation nothing
will happen. So the people who want it can either

1) Buy a machine and do the job
2) Buy a machine and donate it to someone in exchange for doing the job.
