I was going to say something to that effect. *sigh*
I believe MVS is selling/running on a greater number of copies now than
it ever has in the past.
Also, in other messages in this thread, people have been saying stuff to
the effect that pSeries and zSeries aren't architecturally all that
different anymore. Anyone who says that hasn't used zSeries hardware.
That would be like saying that the Tandem NonStop S is similar to the
SGI Indigo^2 because they're both based on MIPS R4400. Or that the Cray
T3E is similar to the Compaq Alphastation 1200 because they're both
based on Alpha EV56. Hogwash.
Peace... Sridhar
I have nothing
whatsover backwards and kindly don't make assumptions.
I stated that the "G5" - the PPC970 family - is a dual-core POWER4;
given that I was talking to someone who claims good knowledge of the
POWER processors but seems not to be so /au fait/ with PowerPC, I did
not see any necessity to spell out that POWER4 is a quad-core design.
PPC970 also adds Altivec-compatible SIMD instructions to POWER, but is
a highly capable 64-bit implementation of POWER.
The PPC970 is a dual-core processor? The one I'm typing this on
certainly doesn't seem to be. I'm not
aware of much that modern PPC processers can't do that POWER
can, other than things intended for the support of legacy IBM OSs such
as OS/400 or zOS.
z/OS is a "legacy" OS? Sure doesn't look that way to me.
Am I just blind today or something?
