+HCC Documentation
+============================
+
+
+The Holland Computing Center supports a diverse collection of research
+computing hardware.  Anyone in the University of Nebraska system is
+welcome to apply for an account on HCC machines.
+
+Access to these resources is by default shared with the rest of the user
+community via various job schedulers. These policies may be found on the
+pages for the various resources. Alternatively, a user may buy into an
+existing resource, acquiring 'priority access'. Finally, several
+machines are available via Condor for opportunistic use. This will allow
+users almost immediate access, but the job is subject to preemption.

+
+Which Cluster to Use?
+---------------------
+
+**Crane**: Crane is the newest and most powerful HCC resource . If you
+are new to using HCC resources, Crane is the recommended cluster to use
+initially.  Limitations: Crane has only 2 CPU/16 cores and 64GB RAM per
+node. CraneOPA has 2 CPU/36 cores with a maximum of 512GB RAM per node.
+
+**Rhino**: Rhino is intended for large memory (RAM) computing needs.
+Rhino has 4 AMD Interlagos CPUs (64 cores) per node, with either 192GB or 256GB RAM per
+node in the default partition. For extremely large RAM needs, there is also
+a 'highmem' partition with 2 x 512GB and 2 x 1TB nodes.

+User Login

+
+For Windows users, please refer to this link [For Windows Users]({{< relref "for_windows_users" >}}).
+For Mac or Linux users, please refer to this link [For Mac/Linux Users]({{< relref "for_maclinux_users">}}).
+
+**Logging into Crane or Rhino**
+
+{{< highlight bash >}}
+ssh <username>@crane.unl.edu
+{{< /highlight >}}
+
+or

+{{< highlight bash >}}
+ssh <username>@rhino.unl.edu

+
+Duo Security
+------------
+
+Duo two-factor authentication is **required** for access to HCC
+resources. Registration and usage of Duo security can be found in this
+section: [Setting up and using Duo]({{< relref "setting_up_and_using_duo">}})
+
+**Important Notes**
+
+-   The Crane and Rhino clusters are separate. But, they are
+    similar enough that submission scripts on whichever one will work on
+    another, and vice versa (excluding GPU resources and some combinations of
+    RAM/core requests).
+     
+-   The worker nodes cannot write to the `/home` directories. You must
+    use your `/work` directory for processing in your job. You may
+    access your work directory by using the command:
+{{< highlight bash >}}
+$ cd $WORK
+{{< /highlight >}}
+
