About UNITE
UNITE is a SGI ORIGIN 2000 system, consisting of
128 CPU's (250 MHz, 4Mbyte cache each), 56 Gbyte
memory and 512 Gbyte disk space. The system has a
capacity of 64 Gflop/s.
UNITE is a so-called CC-NUMA machine. The term
CC-NUMA stands for Cache-Coherent Non Uniform
Memory Access. In the CC-NUMA model, the system
runs one operating system and shows only a single
memory image to the user even though the memory is
physically distributed over the processors. Since
processors can access their own memory much faster
than that of other processors, memory access is non
uniform (NUMA). In this architecture the contents
of the various processor caches should be coherent
requiring extra hardware and a cache coherency
protocol. A NUMA computer fulfilling these
requirements is called a CC-NUMA machine.

About SARA
SARA Computing and Networking Services is a
center of expertise in the area of computers and
networks. SARA supplies a complete package of High
Performance Computing- and infrastructure services,
based on state-of-the-art information
technology.
SARA was founded in 1971 by the Free University
in Amsterdam, the University of Amsterdam and the
Mathematical Center. In 1985 SARA acquired the
status of National High Performance Computing
Center and hosted the Dutch national supercomputer.
Apart from this SARA hosts a number of other
supercomputers, some of which in co-ownership with
other universities.
SARA specializes in:
- High Performance Computing (production,
manipulation, simulation and visualization of
data)
- High Performance Networking
- Information Management
- Facility Management of computer systems and
networks.
SARA offers her customers:
- High performance computer systems: vector,
shared memory and distributed memory
- Experimental systems
- Virtual reality (CAVE and ImmersaDesk)
- Bulk data storage
- Advanced national and international
networks
- Vast expertise in the areas of High
Performance Computing and Networking,
parallelization (PECA), optimalization of
software, virtual reality and facility
management.
