Being a computer physicist

This is much better than a stupid introduction...

This image is a simulation snap shot at t=10 ps, of Al ultra-thin film with 6 nm thickness. The simulation cell contains around 250.000 atoms. Color represents local density. In this simulation the EAM Al potential from Mishin was applied.
Non-optimized ObjectMD code needed 2.5 days to simulate this system up to 50 ps, using 16 processors.

My baby cluster

Some programming projects

I have built my own molecular-dynamics code, the so called Object Molecular Dynamics. And now I changed its name to SimGen! I run simulations in cluster computers. Those are media of my eternal affair with bugs. The place where I can search them, and force them to a sweet surrender. But bugs are eternal. Bugs will never die...

I put some of projects at google codes

Here is the list of my code. You can download it, and just tell me if you find some bugs, or new ideas, or whatever.

• Object-MD --- Object oriented molecular dynamics program, written in c++. I create it for my study purpose. But of course I have ideas more than that. You can find a small document about how to use, here: omdguide.pdf . The development log file can be read at Object-MD Log. Sorry if the discussion in log file does not relate directly to this source file. Its my personal log relating to this program, and I do not put all its applications. Check also at Google Code (http://code.google.com/p/object-md/).
  WARNING! Out of date! Drop me an email if you really need it. I will give the working version from my local repo.
  
• RenderBall --- A script to render an atom-position file to an image. The document describes how to use this program can be read here, and about how to make movie with MakeMovie can be seen here.
• Slider a.k.a TextSlider --- This is the presentation creator using swfc. This program take a plain text file as an input and parse it to an swfc script. The program depends on latex and convert (ImageMagick), and other conversion tools. The output is a presentation file in swf format. Flashplayer or Firefox can be used as the presentation player.
