The cluster is a network of machines with distinct roles, not a single computer.

Head Node (mibgard)
--------------------

**Purpose:** This is the entry point of the cluster. Use it to log in, edit code/scripts, manage and view your files, submit jobs, and perform other light interactive activities.

**Restriction:** Do not run analysis or heavy computations here. Jobs running on the head node may be terminated immediately to preserve resources for other users.

**Hardware:** 128GB RAM, 8 cores 16 threads (Intel Xeon D-2146NT 3.0GHz)

**Disks:** local scratch 2TB

Interactive Node
--------------------

**Purpose:** This node is used for interactive jobs and serves as the web server for tools such as Jupyter Notebook, RStudio, and other web-based applications.

**Restriction:** Direct login is not permitted. Jobs are submitted through the web interface only. This node is intended for testing and short interactive sessions, not for production workloads.

**Hardware:** 128GB RAM, 8 cores 16 threads (Intel Xeon D-2146NT 3.0GHz)

**Disks:** local scratch 2TB


Compute Nodes
-------------

**Purpose:** These machines perform the actual data analysis. Users cannot log in directly; SLURM jobs are submitted via the head node. It is also possible to request an interactive session for testing via slurm.

**Restriction:** Dedicated to slurm jobs. Direct logins are not permitted.

**Hardware:**
1x Standard Nodes: 380GB RAM each, 96 cores 192threads (AMD EPYC 9654P @ 3.71GHz)
1x High-Memory Node: 1 TB (1024 GB) RAM, 96 cores 192threads (AMD EPYC 9654P @ 3.71GHz)

**Disks:** local scratch 2TB
