I'm doing a project where I need to analyze the differences between functional programming and imperative programming. I'm using Scala since it's a multi-paradigm language, for a fair comparison.
Using languages that have a front-end on gcc, pin and perf(hardware) are suitable tools to do these comparisons, but now on Scala, I'm not finding substitutes.
I'm not interested on microbenchmark that only observe the time it took to run the algorithm. Since it's a conway's game of life implementation, a number of memory access is required and so on. I'm grateful for any help

I would recommend ScalaMeter. It is a microbenchmarking tool, but it does what you want by running the code multiple times, and removing the effects of JIT compiler warm-up, garbage collection, etc. It can also be configured to report memory usage, etc.

I am fairly new to modelica. I would like to know if there are any simple libraries that are easily understandable available for download? Libraries that have examples whose total equations do not go beyond 100 or so?
Take a look at the IntroductoryExamples library available with SystemModeler. It shows some of the important parts of building your own library. There's a guide that will guide you through the process called Getting Started.
You could try DrModelica in OpenModelica Notebook. It comes with OpenModelica and is sort of interactive Modelica tutorial. Just start OpenModelica Notebook.
My book, "Modelica by Example", is available for free online. In the second part, "Object-Oriented Modeling", you'll find a complete discussions of how to build connectors, components, packages, subsystems and architectures.

I am working with scala for couple on months.
I want to focus on functional programming using scala . I am looking for a book that shows real world application using scala . and preferred (if there is one) with TDD approach
books that I read are concept and syntax , now I want to dive in FP programming using scala with TDD approach and looking for a good tutorial using real world applications as a reference .
any recommendations ?
For functional programming with Scala, here are a few suggestions:
http://www.artima.com/shop/programming_in_scala_2ed
http://www.manning.com/bjarnason/
http://www.manning.com/raychaudhuri/ (this one mention TDD in a couple of chapters)
Just found this book testing in scala which is close to what I was looking for

I wan't to get introduced to the fundamental concepts of Category Theory, from a developer's perspective (not a math student), but every single resource I see uses Haskel, Scala, F# or other highly-focused languages that I don't use.
Are there any resources for the rest of us?
MIT has an some course material online for Category Theory for Scientists. There is also a textbook you can download as well.
Pierce's Basic Category Theory for Computer Scientists fits your description. It is in no way tied to any particular programming language.
When learning category theory It's good to have examples to work from. If you don't have examples from mathematics, and you don't have examples from specific programming languages, it might be hard to motivate the subject.

I'm looking for a role-playing game framework which fulfills the following critera:
Open source / Free for non-commercial
Targeted language doesn't matter as long as it's not too obscure (C# or Java would be great)
The framework doesn't have to provide any graphics, sounds or other "low level" stuff
The framework should support complex, non-linear story lines (like Fallout 1/2/3)
The character should be highly configurable (again like Fallout or Dragon Age)
Support for a party would be nice
Check out GemRB, a port of the Infinity Engine (i.e. Baldur's Gate). It's licensed under the GPL and written in C++ and Python if I'm not mistaken. Since it's based on the Infinity Engine, I would assume that all of the last three requirements apply as well.

Excluding Cocoa (and its NSThread), what multithreading libraries would you recommend?
The application's engine must run on multiple platforms (Windows, Linux, MacOS, iPhone), and be multithreaded. Abstracting the library to compile against platform-specific MT libraries is possible, but incurs an extra layer of overhead and complexity.
NSOperation works fine. As an added bonus you get a thread pool for free, and can setup a dependency chain between operations.
How about something in the C library area?
e.g libapr: http://apr.apache.org/docs/apr/1.3/group__apr__os__thread.html
or glib?

I would start with Grand Central which was recently open-sourced: http://libdispatch.macosforge.org/
