Garðar started its life in the NHPC project.

Garðar is an HP BladeCenter cluster consisting of one frontend (management, head) node, 2 login nodes and 233 compute nodes running Centos Linux managed by Rocks. Each node contains two Intel Xeon Processors with 24GB memory. The compute nodes are located in HP racks. Each HP rack contains three c7000 Blade enclosures where each enclosure contains 16 compute nodes.

Garðar has a separate strorage sysetm. The X9320 Network storage system is available to the entire cluster and uses the IBRIX Fusion software. The total usable storage of X9320 is 71.6TByte. The storage system is connected to the cluster with an Infiniband QDR network.
