+title: Building a mini HPC - a bit of an update
+---
+
+Since starting this project a couple of years ago, some work has gone into Pixie (our miniHPC).

+
+We are now up to five compute nodes and a login node. 
+
+# Current hardware configuration:
+
+1. 6 x Raspberry Pi 4 with 4GB
+1. 6 x PoE hats
+1. 1TB SSD
+1. Dual USB fan
+1. TP-Link 10 port PoE 150W (30W per port) switch
+
+# Software
+1. Slurm
+1. Munge
+1. lmod
+1. EESSI
+
+We use PXE so that our nodes are diskless. The PoE does away with all the power supplies and we have exactly one power cable.
