Is A Sun Fire T2000 SMP ?

Is A Sun Fire T2000 SMP (Symetric MultiProcessor) ?

I've seen this question asked a few times. This question is need to be broken down into 2 parts.


How many sockets does the T2000 have? - There is 1 socket for a UltraSPARC T1 processor .


The T1 processors contains 8 cores running 4 threads per core. Giving us 32 simultaneous processing threads on 1 die.


Symetric MultiProcessing describes the operating system feature of scheduling any task to any processing thread (Previous we would used CPU but the term CPU has become confused) it requires some underling hardware features cache coherency as an example to function efficently.


So the T2000 is a SMP computer but all of the SMP functions happen on 1 piece of silicon. This is a wow moment it! When you think of a T2000 as computer having 8 cores and the cache coherency and other SMP processes only takes a few cycles you see why it can outperform a multi-socket Xeon box .


Comments:

I have one major question: Will machines like the T2000 support a 64 bit JVM with a heap size of say, 24 GB (with 32GB of memory)? What other machines in the same (or less!) price range will support such large heap sizes? Please reply directly to me (also). Thanks.
