Can ctor throw exception? Why do you say it's not best practice?

How does a vector resize?

What kind of algo is qsort? Average and worst runtime complexity?

Recursive vs iterative, which is faster?
A: comparable, but space complexity lower for iterative?

what's lockfree? How did you make it work in your projects?

How did you use parallel processing in GS?
A: data parallellism, threading, and other techniques. Coarse-grained is ideal.
A: i guess pipelining parallellism is also relevant, using task queues
