I was a little bummed that we didn't get our quad 8-core T2000 for more
than a week.  We weren't able to setup any of the fun management to take
full advantage of it.  And today I learned that each core has 4
"strands" of execution such that a core need not suffer from memory
access delays.  See http://www.sun.com/blueprints/1205/819-5144.pdf for
details.
 
Sounds like it could be interesting.  Very interesting...  :)

        We just went through a licensing analysis for the T1000 and the
Multicore processors,.. in the Oracle licensing document it states that
for Intel Multi-Core system the algorithm is the number of cores * .25
for the processor license. For IBM and/or HP (I might be off a little
here cause we didn't dive into the HP and IBM processors) but I believe
it stated the #processors * .5.
        
        For SUN Multicore processors the algorithm was the #cores * .75
so for 8 cores the license would be the same as it is for 6 processors

                MessageCan you elaborate on "use all those cores
simultaneously"? Would a
                parallel query not use all the cores, or heavy
concurrent access by users?
                Imagine the licensing cost if you had two or three of
these in a rac?
