At the moment there is only a VASP 5.4.4 with cnms patches. If you use it do not ignore the aprun binding flags.
## AMD Interlagos Architecture
Like Titan and OIC Phase 5, Metis uses the AMD interlagos chip. With these cpu there is only one floating point per 2 cores. From the perspective of most scientific computing this means a the number of cores is halved. If you don't correctly map your processes onto the nodes you'll waste significant computing time.

We don't have best practices to suggest at this time. Consider having a script you manually source if you have trouble. The order in which the files are loaded is different on Cray XK and Centos.
## Power Users
You can build codes in:
```shell
/sw/user_tools/cades-cnms
```
This is accessible from the compute nodes while home is not.
please let @epd know of builds you are confident of and we can make modules as well as document the recipe.
Be aware that this is not a place for private directories and your directory permission may be changed without notice.
Outside of the shared directories and actual modules installed Metis is basically a small chunk of Titan.
