The Kongsberg Informasjonskontroll SCALI system.

Machine type RISC-based distributed-memory multi-processor
Models SCALI
Operating system SunOS (Suns Unix variant)
Connection structure SMP-nodes connected by ring (see remarks)
Compilers Fortran 7790, C and C++

System parameters:

Model SCALI
Clock cycle 6.7 ns
Theor. peak performance
Per Proc. (64-bits) 150 Mflop/s
64-bits precision 76.8 Gflop/s
Main memory <=16 GB
Memory/node <=0.5 GB
Communication bandwidth 1.2/1 GB/s
No. of processors 1-512

Remarks:

The SCALI system is a non-uniform access system: it consists of SMP nodes that can contain up to 4 processors. The configuration discussed here uses HyperSparc 6.7 ns cycle processors but also HyperSparcs of lower speed or SuperSparc-II processors could be used, showing that the architecture is essentially processor-independent. The SMP nodes are connected by Internode Communication Channel (ICC) links based on SCI, with a bandwidth of 1 GB/s. This is hardly less than the internal bandwidth of 1.2 GB/s of the SMP nodes.

The connection between SMP nodes may be a single ring but richer connection structures, like a ring of rings, a multi-level crossbar are possible for those willing to pay for it.\\ The available compilers provided by Applied Parallel Research are: Fortran 77 and Fortran 90, C, and C++, with facilities for automatic parallelisation. Kongsberg Informasjonskontroll provides a proprietary MPI implementation, MPI-I, for its systems. In addition the KAP preprocessor is available.

In the USA the same system is marketed under the name AxilSCC by Axil.

Measured Performances: The SCALI system is very new. No performance figures are available at this moment.
