Extreme Sports and the SPARC T5 Chip

In my day, you were extreme if you surfed. Nobody had a leash. If a wave ripped the board out of your hands, you had to swim all the way back to the beach. In big surf, that could take 15 minutes. And then you had to paddle out again.

Today, if you're not juggling rusty chainsaws while riding a BMX bike off the top of the Eiffel Tower with half a dozen angry chimpanzees trying to rip off your helmet and goggles, you're not considered extreme.

Which is exactly why the SPARC T5 chip has 1024 functional CPUs. None of Oracle's SPARC engineers wanted to find himself at a cocktail party having to confess in an embarrassed chortle to a salon full of top hats and sequins that he had designed a mere 512 CPU chip. Imagine the chagrin!

So Oracle's SPARC engineers worked wicked hard to scale the T5 to eight sockets. Since each socket has 16 cores, that gives you 128 cores, total. Since each core can support eight individual threads (or strands, if you're not the sartorial type), you wind up with a total of 1024 functional CPUs.

As you know, processing power without bandwidth is kinda like a mega motor with a nano fuel tank. Doesn't get you too far. So the T5 also has memory bandwidth to match its processing power. And lots of other capabilities that you an read about in this:

P.S., If you want to read about surfing in the old days, check out Chapter 1 of Tocayos, a novel I've been writing and posting online in my spare time.
