	   the 3520 is a 2 processor machine, but I can't tell.  I mean,
   it sez that "processor b is started," but a ps gives no indication of
   parallelization, even at the processor level.  On a Gould, a ps will
   tell you which cpu your job's on.  So what gives?  Does the machine
   run both cpus or not really.

Yes, I hear you.  I have the same question regarding our VAX6320 running
Ultrix 3.1.  While troubleshooting a problem, we ran without the second 
CPU for a while.  Guess what, nobody noticed.  Deeply embarrassed the
people who spec'd the buy.

I have heard that there exists a piece of code called "the Scheduler Patch"
which is supposed to vastly improve the utilization of the second CPU
(at least on 6x20s and it is the same proc, right?).

The same source reports that this non-product is from Ultrix pre-sales,
wherever they might be.  I was told by my source that my sales-expletive
("We just sell 'em!") could get it for me.  

To make it even more bizarre, I've also heard that this thing is supposed
to be in the phantom maintenance release 3.2, of which no one else has
ever heard.

Anyone at DEC care to elaborate or dispell any of the possibly bogus 
stuff I've heard.

Oh yeah, while we're at it, how about an upgrade path to the RISC family
for all this metal so we can run MACH?

				Disappointed,
