Here's our latest training/outreach cluster based on Radxa X2L SBCs
4 nodes of quad-core X86 Celeron
8 GB memory/node
PoE local power control through switch
Rocky 9.3 OS
Warewulf 4.5 for node provisioning
We’ll soon add (as on our other ones already built and to come) Slurm, Spack, and a suite of HPC applications
Head node has 2TB of NVMe storage nfs mounted to the worker nodes, which are diskless and stateless
Total cost about $700 (full parts list and accounting to come)
Note the carry handle!
@AlanSill I am genuinely amazed that this is only $700. Well done!
