(snip of clock rate comparison)
Clock rate is almost never useful for comparing between
different types of processors, or even different versions
of similar processors. There are many design tradeoffs

This behavior is not unique to VM at all -- it's exactly equivalent to
hitting L1-A on a Sparc console and leaving it sitting at the ok PROM
prompt -- you don't let people near your Sparc consoles if they don't
know how to fix what they
I found the solution to the problem I had with an Oracle 10g
installation. By reading the full install manual for Oracle 10g for
Linux x86-64, (several hundred pages, instead of the 20 or so pages for
a quick install), I found that it seemed to need an entry in the
/etc/hosts file.

Normally, you only need to worry about access due to
other CPU's or channels.
For an interruptible instruction, you also need to worry
about access by other tasks on the same CPU.
In the olden days, the interval timer at address 80 could
be updated with an MVC instruction. The new value was
The 360/91 and maybe the 6600 were prominent in books
on pipelined architectures for many years.
The goal of the 360/91 was one instruction per clock cycle,
so not superscalar, but still a tough goal with slow core
memory. (16 way interleaved, but at over 10 times the
cycle time.)

I think this has been discussed in other lists, but not this
one. Because of the 4K key so-called feature, running VM/370
on a P/370 or P/390 in S/370 mode requires that CR0 bit 7
be set. Unfortunately, VM/370 doesn't normally do that.
VM/370 changes CR0 in many different places, and all those

There is discussion on another list about the ability to
run MVS software under L/390.
This would seem to me to be similar to what CMS does when running
MVS object or load modules. One requirement is to emulate
the system SVC's. Two things are needed: that Linux doesn't use the
required SVC's
