-===== High-performance simulation of large bimolecular systems - NAMD ===== 
-NAMD, recipient of a 2002 Gordon Bell Award, is a parallel molecular dynamics code designed for high-performance simulation of large biomolecular systems. NAMD is file-compatible with AMBER, CHARMM, and X-PLOR and is distributed free of charge with source code. 
-Documentation and source code on the web page of "[[|Theoretical and computational biophysics group]]" 
-There are few possibilities to start NAMD simulation on the MOGON cluster. 
-//<PATH TO NAMD INSTALLATION>/namd2 <input configuration file>// 
-This starts one threaded simulation direkt on the login host. Input configuration file describes simulation. Complete description of the input file format is available in the [[|NAMD Documentation]]. 
-Using threaded start allows to achieve performance increasing: 
-//bsub -R "affinity[core(<number of cores>)]" <PATH TO NAMD INSTALLATION>/namd2 +p<number of threads> <input configuration file>// 
-where <number of threads> is normally equal to <number of cores>. 
-For example 
-//bsub -R "affinity[core(16)]" <PATH TO NAMD INSTALLATION>/namd2 +p 16 <input configuration file>// 
-starts NAMD simulation with 16 threads using 16 cores of a node. 
-Mogon cluster consists different nodes with up to 64 cores. 
-On machines with more than 32 cores it may be necessary to add a communication thread and run on one fewer core than the machine has.  For example on a 64-core machine this would be run as 
-//bsub -R "affinity[core(64)]" <PATH TO NAMD INSTALLATION>/namd2 +p 63 +commthread <input configuration file>//
