# OIC Docs
|
|
|
As explained in this [document](http://www.cnms.ornl.gov/capabilities/CNMS_ComputerCluster.pdf) CNMS's portion of the OIC cluster consists of several phases. Each one is a distinct platform. For now these documents only support phase 5. If there is demand for it we can prepare some phase 3 docs. Outside of that the hardware is extremely obsolete but may be useful for your own codes if they are low impact.

### LAMMPS

|
|
Has undergone only minimal testing via the examples. Additionally I may have not built important extensions, I don't know which user written extensions are usually used. Happy to build these.

### VASP
|
|
|
The vasp module is optimized for oicphase5 and may not run at all on other phases. It is significantly better than some previous builds and has the newest patches as well as the CNMS extensions. If a PBS script like the provided example is used another 50-100% speed up can be achieved.
