You need basic proficiency in Linux environments.
Basic proficiency in Linux environments is required.
In order to use the system for your calculations, you need basic proficiency in Linux environments. To gain this proficiency, we recommend you read the [introduction to Linux][c] operating system environments, and install a Linux distribution on your personal computer. A good choice might be the [CentOS][d] distribution, as it is similar to systems on the clusters at IT4Innovations. It is easy to install and use. In fact, any Linux distribution would do.

Learn how to parallelize your code!
Learn how to parallelize your code.
In many cases, you will run your own code on the cluster. In order to fully exploit the cluster, you will need to carefully consider how to utilize all the cores available on the node and how to use multiple nodes at the same time. You need to **parallelize** your code. Proficiency in MPI, OpenMP, CUDA, UPC, or GPI2 programming may be gained via [training provided by IT4Innovations][e].
