16 x 4 != 128 ;)Quote:
The latter manages to combine four of the processors with up to 512GB of RAM for a 128-core, 512-thread monster.
Although 16 x 4 x 8 == 512, so I assume it is just a typo :D
Each core is capable of 8 simultaneous threads so 4 processors x 16 cores x 8 threads = 512 threads!Quote:

Yes, hence my statement that 16 x 4 x 8 == 512. My point was that a 4 processor server would have 64 cores, not 128 as stated in the article :rolleyes:Quote:

Details are given in http://www.redbooks.ibm.com/abstract...4640.html?Open if you're interested.
Okay, the 795 probably costs as much as half a housing estate, and is a full rack to itself rather than slotting alongside other kit like the T3 kit will. On the other hand, the IBM gear IS pretty neat - the RAS and virtualization stuff especially - and it runs Linux too if you want (RHEL and SLES fully supported!). And best of all ... you don't have to deal with Oracle. :puke:
Apologies for bigging up Big Blue, but I've got to give 'em credit where due. Even if they are the main competitor to my employer! :mad:
