+Slurm is installed on a PE2950 with dual quad cores and 16 GB of memory. It is part of my high priority queue and allocated to Openlava (v2.2).
+My slurm compute nodes (v1-v8) are created in a virtual KVM environment on another PE2950 (2.6 Ghz, 16 GB ram) dual quad core with hyperthreading and virtualization turned on in the BIOS. Comments on how to build that KVM environment are here [[cluster:132|LXC Linux Containers]]. The nodes are single core, 1 GB or ram.
