I'll take a T932 over _anything_ you can carry by >hand, no questions asked. The Cray the NWO owned a bunch of years ago was replaced by the 1024 processor TERAS machine in 2000. It now is upgraded to 1440 processors. That is a new machine with 416 processors is added to it. Most jobs they found out at the TERAS were either up to 8 cpu's or up to 32 cpu's. >>I'm not sure about the microprocessor designs, we can ask AMD and intel after >>it.

That's funny because i do not own a single apple product AFAIK. My sister does though. That's typical however as she is a graphics artist and VJ and makes a small chance to get our first female prime minister :) >> >>However about the weather forecasting guess why the 1024 processor from december >>2002 till end of gulfwar II was overloaded with weather guys :) >> >>It was like this.

The T90 typically has 16-32 gigs. that's funny because that poor Cray T916 which was replaced by the TERAS, it has 1 terabyte since 2000 already. It has soon nearly 2. The climate job that runs now at the TERAS needs around 350000 cpu hours and 10 terabyte of i/o, so 1 TB memory is more than welcome for it. When it would run on the old Cray T916 (strong oxens) that would take 150 years it says. Best regards, Vincent
