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

                From an Oracle licensing perspective, 8 cores in the niagra processor count as one processor for Oracle licenseing purposes.

		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?
