I believe that at the right level of abstraction, it is not and in fact can be as easy as sequential programming. Note, however, that "at the right level of abstraction" should be considered with care. Pragmatically there are some problems today with taking advantage of the "easiness" of parallel programming.
(d) Hardware programming languages are concurrent in nature and executed a piece of code in parallel while a software programming language are sequential in nature and executed a piece of code sequentially.
A programmer writes source code that tells a computer what to do. Traditional programming is procedural, meaning it is imperative and stateful; it tells the computer sequential steps to execute. The problem with traditional programming is that it does not lend itself to parallel processing. To get around that, programming paradigms such as functional programming tell the computer what to do in more general terms, but not the order of execution. Several of the program's instructions can be executed simultaneously.
Sequential order arranges things or is an arrangement of items in a predicable order; like pages of a book.This is not the same as chronological order which sorts by the oldest to the newest.........................Bob saget
Parallel.
In the early days of computing, the dominant programming languages weresequential(such as basic or assembly language). A program consisted of a sequence of instructions, which were executed one after the other. It ran from start to finish on a single processor.reference: http://code.google.com/edu/parallel/mapreduce-tutorial.html

Some key differences between a Serial and Parallel Adder are that a Serial Adder is slower, a Parallel adder is a combinational circuit and the time required for addition depends on the number of bits in a Serial, but not a Parallel. A Serial Adder is a sequential circuit while a Parallel is a combinational circuit.
