Introduction
Brutus is a central high-performance cluster of Template:ETHZ. It is jointly owned by nearly 50 professors in 12 departments and the IT Services, who are responsible for the acquisition and management of the system.

Compute nodes
Brutus is a heterogeneous system containing 11 different kinds of compute nodes:
- Standard nodes
- 120 nodes with four 12-core AMD Opteron 6174 CPUs and 64 GB of RAM (5760 cores)
- 24 nodes with two 12-core AMD Opteron 6174 CPUs and 32 GB of RAM (576 cores)
- 410 nodes with four quad-core AMD Opteron 8380 CPUs and 32 GB of RAM (6560 cores)
- 80 nodes with four quad-core AMD Opteron 8384 CPUs and 32 GB of RAM (1280 cores)
- Large-memory (fat) nodes
- 6 nodes with four 8-core Intel Xeon E7-8837 CPUs and 1024 GB of RAM (192 cores) — NEW!
- 80 nodes with four 12-core AMD Opteron 6174 CPUs and 256 GB of RAM (3840 cores)
- GPU nodes
- 18 nodes with two 12-core AMD Opteron 6174 CPUs, 32 GB of RAM and 2 Nvidia Fermi C2050 GPUs (432 cores + 36 GPUs)
- 2 nodes with two 6-core AMD Opteron 2435 CPUs, 32 GB of RAM and 6 Nvidia Tesla C1060 GPUs (24 cores + 12 GPUs)
- 2 nodes with two 6-core AMD Opteron 2435 CPUs, 32 GB of RAM and various Nvidia and AMD GPUs (24 cores + 2 GPUs)
- Legacy nodes
- 256 nodes with two dual-core AMD Opteron 2220 CPUs and 16 GB of RAM (1024 cores)
In total Brutus contains 19,872 cores, plus a few hundreds in the cluster's file servers, login nodes and management nodes.
The peak performance of Brutus is slightly over 200 teraflops (200 × 1012 floating-point operations per second).
Networking
- All nodes are connected to the cluster's Gigabit Ethernet backbone
- All nodes (except the 256 with Opteron 2280 CPUs) are connected to a high-speed InfiniBand QDR network
Trivia
- Brutus was ranked the 88th fastest computer in the world in November 2009 (top500.org)
- It was at this time the most energy efficient general purpose supercomputer in the world (Heise.de)
