:)Hi, everyone!
Anybody use Ubuntu to do molecular dynamics(MD)?
And Use NAMD?
Is it good?:):)

no,I haven't.
But I am interested in this topic, Molecular Dynamics .I am majoring in physics.
Would you mind do me a favor to introduce the soft of NAMD or other else that can be used in this field?
Many Thanks~

Ok. NAMD is a parallel molecular dynamics code designed for high-performance simulation of large biomolecular systems. Based on Charm++ parallel objects, NAMD scales to hundreds of processors on high-end parallel platforms and tens of processors on commodity clusters using gigabit ethernet. NAMD uses the popular molecular graphics program VMD for simulation setup and trajectory analysis, but is also file-compatible with AMBER, CHARMM, and X-PLOR. NAMD is distributed free of charge with source code. You can build NAMD yourself or download binaries for a wide variety of platforms. Our tutorials show you how to use NAMD and VMD for biomolecular modeling.

my major is biophysics & condense matter physics
HAVE A TRY! FRIENDS

MD is a part of my research, but I write my own programs. I suggest you do the same if you really want to understand what is going on.

Another good alternative if you have limited resources is Gromacs. It is available in the repositories (its under the GPL), and is much faster than NAMD for small numbers of processors. Benchmarks performed here show that for a membrane protein system, Gromacs is ~10x faster than NAMD on a single processor, and despite the better scaling of NAMD you still need 72 processors before NAMD starts outperforming Gromacs.
I don't think that writing your own MD code is necessary unless you really want to develop it; there are several highly optimised code bases out there (including NAMD, Gromacs, Charmm, and others) which will be faster and have passed intense peer review. If you just want a simulation of a biomolecule you are better reading the documentation and using one of these. Alternatively, if you want to understand the details of how the code works, I believe that there is a program called tinker which is very readable/hackable.

Well, you also have Tinker (http://dasher.wustl.edu/tinker/) as an alternative.
