outside of a few details though the setup is exactly like titan, so these should be on your path to getting things to work:
## 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.
usually you'll want something like:
```shell
aprun -j1-S4-n(totalcores/2)-r1$CODE
```

## $HOME and /lustre/or-hydra/cades-cnms scratch area are shared with CASDES-CONDO
This means you need to be careful with paths, and your .bashrc and .bash_profile files.
You're going to need something like
```shell
if[[$HOSTNAME=~ metis ]]
then
fi
```
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.
Outside of the shared directories and actual modules installed Metis is basically a small chunk of Titan.
