Wolfram Alpha vs. Google — Results Vary 255

For example, searching 'Microsoft Apple' in Alpha returns data comparing both companies stock prices, whereas Google top results are news stories mentioning both companies. However, when searching for '10 pounds kilograms,' Alpha rather unhelpfully assumes you want to multiply 10 pounds by 1 kilogram, whereas Google directs you to sites for metric conversions. Change the query to '10 pounds in kilograms' and both give you the result you'd expect (i.e. 4.536 kg)."

I worked on the RAW project as an undergrad and started work on a shared memory network for it. The interconnect is actually controlled as part of the instruction set just like the processors. Back then it was only 16 cores on a chip. The way I setup the shared memory network was to use the edge processors to act as the controllers for the off chip memory they were connected to. The other processors would send requests for reads and writes to the appropriate edge processor. I'm sure that their current method is significantly different than what I designed.

Each processor had some cache and there was also a special messaging network used to get to off chip non-shared RAM.

If you really want to get into the details:
