# CPU Cluster Romeo
+## Overview
+
+The HPC system `Romeo` is a general purpose cluster based on AMD Rome CPUs. From 2019 till the end
+of 2023, it was available as partition `romeo` within `Taurus`. With the decommission of `Taurus`,
+`Romeo` has been re-engineered and is now a homogeneous, standalone cluster with own
+[Slurm batch system](slurm.md) and own login nodes. This maintenance also comprised:
+
+ * change the ethernet access (new VLANs),
+ * complete integration of `Romeo` into the `Barnard` InfiniBand network to get full
+ bandwidth access to all new filesystems,
+ * configure and deploy stand-alone Slurm batch system,
+ * newly build software within separate software and module system.
+
+!!! note "Changes w.r.t. filesystems"
+
+ Your new `/home` directory (from `Barnard`) is now your `/home` on *Romeo*, too.
+ Thus, please
+ [migrate your `/home` from Taurus to your **new** `/home` on Barnard](barnard.md#data-management-and-data-transfer).
+
+ The old work filesystems `/lustre/scratch` and `/lustre/ssd will` be turned off on January 1
+ 2024 for good (no data access afterwards!). The new work filesystem available on `Romeo` is
+ `horse`. Please [migrate your working data to `/horse`](barnard.md#data-migration-to-new-filesystems).
