Programming language where every function call/block is done in a separate thread?
every function call/new block (if clauses, loops etc) will work in a separate thread.
Read a lot more about continuations and continuation-passing style (and their relation to threads or coroutines) ...

Programming language where every function call/block is done in a separate thread?
This is exactly what Erlang does. It handles rejoining the threads mostly by using queues. It`s a brilliant concept but a bit difficult to wrap your head around initially if your background is more ...

Immediately awaiting an asynchronous call
I think you misunderstand the await call. What async and await do is allow the thread you are executing on (not just the main thread) to continue working. The mechanism that supports this is called ...

How do I know if a set of code is a good candidate for parallelization?
You know code is a good candidate for parallelization when it can be broken into a set of "discrete" (i.e. independent) tasks. A discrete task is one that produces a specific result and has no side ...

How Functional Programming addresses concurrent increment/decrement operations invoked by different users?

Workflow for designing a parallel architecture
I suppose this could be application-specific? I.e., some codes written in serial may need to be significantly modified in order to be parallelized?

Design for avoiding concurrent calls to an interface implementation
First, I would create a decorator / wrapper that synchronizes calls, instead of putting it into implementation.

Parallel sorting algorithm that compares all elements
If the comparison metric is a boolean (as indicated in the comments), then there are two possibilities.
The metric is transitive (if comp(A, B) yields true and comp(B, C) yields true, then comp(A, C) ...

How to approach a large number of multiple, parallel HttpClient requests?
The first rule when talking about performance is to measure. The built in tools in visual studio is fairly competent, and in a pinch, adding a stopwatch or two can help reveal what part of the code is ...

How can I improve the speed of scanning multiple directories recursively at the same?
First thing to understand is that threading is a form of parallelism. The differences between separate threads and separate processes are not all that important in this case.

Is sequential consistency equivalent to performing memory accesses by a processes in program order and performing each memory access atomically?
No, your definition is not quite equivalent to the definition of sequential consistency but would be closer to strict consistency. There are two relevant aspects: (a) there are multiple processors/...
