Beda is scheduled for decommissioning at the end of 2014.
The capacity cluster cluster consists of 268 compute servers (nodes) and five system servers. Each of the compute nodes are equipped with two Quad-core Intel® Xeon 5520 (Nehalem 2.26 Ghz, 8 MB cache) processors.
24 of the nodes have 48 GB memory and one has 72 GB memory, while the remaining nodes have 24 GB each.
The interconnect is Infiniband with 20 Gb/s. The system is connected to a gigabit Ethernet.

The Glenn cluster is built on AMD Opteron 6220 (code-named "Interlagos") CPU's. The system consists of:
In total 379 compute nodes (total of 6080 cores) and 18.1 TB of RAM. More specific:
224 nodes with 16 cores and 32 GB of RAM
135 nodes with 16 cores and 64 GB of RAM
13 nodes with 16 cores and 128 GB of RAM
1 node with 32 cores and 512 GB of RAM
4 nodes with 16 cores, 32 GB of RAM and 1 NVidia Fermi M2050 GPU
2 nodes with 16 cores, 32 GB of RAM and 1 PCoIP adapter for remote graphics
There are also 3 system servers used for accessing and managing the cluster.
There's a Gigabit Ethernet network used for logins and file system access, a dedicated management network and an Infiniband high-speed/low-latency network for parallell computations. The nodes are equipped with Mellanox ConnectX-2 QDR Infiniband 40Gbps HCA's.
The server and compute node hardware is built by Supermicro and delivered by South Pole.
