Use of distributed FFT for writing fully distributed N-body code for cosmological applications

Yep, that's the topic of the project I am currently working on. Sounds a lil intimidating, doesnt it?
I had my mid-semester project evaluation last Sunday on 15th March. It was supposed to be a wake-up call for all the final years so that we can start searching about the project, if we haven't started already. Well, I have no issues with procrastination this year, thanks to my mentor. *Old news! I saved the draft of this post on March 18 but was too lazy to publish. Some people never change. I didn't take a look at my project for more than a month and now I am in deep shit :D* As I had already made a report and presentation for the evaluation, I thought of sharing them on the blog.
My presentation is embedded in the blog while my midterm report can be found here.

Writing distributed N-body code using distributed FFT - 1

P.S. So its more than a month after I took up my final semester project. I want to blame the procrastination on GSoC but that aint a good excuse. My mentor is mighty pissed and all I can say now is Dear God. One word. Graduation. Amen!
