Brutus is the central high-performance cluster of ETH Zurich. It was introduced to the public in May 2008. A new computing cluster called EULER has been announced and opened to the public in May 2014. Processors 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)'' * 10 nodes with four quad-core AMD Opteron 8380 CPUs and 128 GB of RAM'' (160 cores)'' ;GPU nodes * 18 nodes with two 12-co ...

Computer Cluster
A computer cluster is a set of computers that work together so that they can be viewed as a single system. Unlike grid computers, computer clusters have each node set to perform the same task, controlled and scheduled by software. The components of a cluster are usually connected to each other through fast local area networks, with each node (computer used as a server) running its own instance of an operating system. In most circumstances, all of the nodes use the same hardware and the same operating system, although in some setups (e.g. using Open Source Cluster Application Resources (OSCAR)), different operating systems can be used on each computer, or different hardware. Clusters are usually deployed to improve performance and availability over that of a single computer, while typically being much more cost-effective than single computers of comparable speed or availability. Computer clusters emerged as a result of convergence of a number of computing trends including ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gigabit Ethernet
In computer networking, Gigabit Ethernet (GbE or 1 GigE) is the term applied to transmitting Ethernet frames at a rate of a gigabit per second. The most popular variant, 1000BASE-T, is defined by the IEEE 802.3ab standard. It came into use in 1999, and has replaced Fast Ethernet in wired local networks due to its considerable speed improvement over Fast Ethernet, as well as its use of cables and equipment that are widely available, economical, and similar to previous standards. History Ethernet was the result of research conducted at Xerox PARC in the early 1970s, and later evolved into a widely implemented physical and link layer protocol. Fast Ethernet increased the speed from 10 to 100 megabits per second (Mbit/s). Gigabit Ethernet was the next iteration, increasing the speed to 1000 Mbit/s. * The initial standard for Gigabit Ethernet was produced by the IEEE in June 1998 as IEEE 802.3z, and required optical fiber. 802.3z is commonly referred to as 1000BASE-X, ...

InfiniBand
InfiniBand (IB) is a computer networking communications standard used in high-performance computing that features very high throughput and very low latency. It is used for data interconnect both among and within computers. InfiniBand is also used as either a direct or switched interconnect between servers and storage systems, as well as an interconnect between storage systems. It is designed to be scalable and uses a switched fabric network topology. By 2014, it was the most commonly used interconnect in the TOP500 list of supercomputers, until about 2016. Mellanox (acquired by Nvidia) manufactures InfiniBand host bus adapters and network switches, which are used by large computer system and database vendors in their product lines. As a computer cluster interconnect, IB competes with Ethernet, Fibre Channel, and Intel Omni-Path. The technology is promoted by the InfiniBand Trade Association. History InfiniBand originated in 1999 from the merger of two competing des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MVAPICH

OpenMP
OpenMP (Open Multi-Processing) is an application programming interface (API) that supports multi-platform shared-memory multiprocessing programming in C, C++, and Fortran, on many platforms, instruction-set architectures and operating systems, including Solaris, AIX, FreeBSD, HP-UX, Linux, macOS, and Windows. It consists of a set of compiler directives, library routines, and environment variables that influence run-time behavior. OpenMP is managed by the nonprofit technology consortium ''OpenMP Architecture Review Board'' (or ''OpenMP ARB''), jointly defined by a broad swath of leading computer hardware and software vendors, including Arm, AMD, IBM, Intel, Cray, HP, Fujitsu, Nvidia, NEC, Red Hat, Texas Instruments, and Oracle Corporation. OpenMP uses a portable, scalable model that gives programmers a simple and flexible interface for developing parallel applications for platforms ranging from the standard desktop computer to the supercomputer.
