UNICOSUNICOS is the standard operating system for VSMP (Cray
Vector Symmetric multi-processor) computers and established
since 1985. It was derived from the UNIX System V, a far common
and well ported operating system programmed in C. The UNICOS
system also was affected by the 4th generation of BSD and
extended by super computing abilities to provide high
performance to support the science and development market.
UNICOS is the first 64 bit implementation of UNIX and a UNIX
similar file system. UNICOS system offers a stable base from
small servers up to gigantic computer plants. Photos: Cray Inc.
The UNICOS system makes extremely flexible and robust
calculating machines with support of the following hard and
software characteristics possible: The UNICOS system is the
first high performance UNIX based operating system which
supports SMP. Multi-processor and multi-threading operating
system The UNICOS system is scalable on more than 32 processors.
Cray aims at a small CPU percentage for the consumption of
