I am developing an iocp server app, in each worker thread I call GetQueuedCompletionStatus() to process IO packets. My question is if I have a machine with more than 1 CPU, will that 2 threads process a same IO packet at same time?

Assuming you're doing everything correctly, no. GetQueuedCompletionStatus will atomically unqueue and return a completion packet; a given packet will only be returned to exactly one thread, regardless of CPU setup.

That's correct (although it might not actually be a linked list, it IS thread safe). That's kind-of the whole point of completion ports.
