Regarding TBB and Intel Libraries

Hi,

[1]

I wanted to understand the difference between the two terms
1. Intel Thread Libraries
2. Intel Thread Building Blocks.

I thought Intel TBB was the same as Intel Thread Libraries but they both seem to be used differently in a couple of documents that I read. Can someone please explain the difference ?

[2]

In one of the surveys on why one needs to adopt multi-core chips and parallel software, other than a host of other good reasons - Form Factor, Security and Cost were cited as some of the reasons (which I did not understand) Can you please explain how these would encourage adoption of multi-core chips and parallel software?

[1] They are probably the same. I didn't easily find any reference to a "library" that wasn't referring to TBB.
>> they both seem to be used differently in a couple of documents that I read.
What docs?

[2] (guesses)
>> why one needs to adopt multi-core chips and parallel software
Form-Factor - take advantage of existing hardware and socket type?
Security - more horse power to run those CPU-time expensive virus scanners?
Cost - muli-core chips are getting cheaper?

>> In one of the surveys...
What survey? Reading it as a whole may make it easier to guess.
