Linux is the name of a computer operating system and its kernel.
Once viewed as an operating system only computer geeks could use, Linux is today a much more user-friendly system, with many graphical interfaces and applications that bear a close resemblance to those of popular consumer operating systems.
The GNU project was started in 1983 for developing a complete Unix-like operating system, including software development tools and user application programs, entirely of free software.

The Cray Operating System (COS), and latter Unicos, are both variants of Unix.
It is a credit to the architecture of these machines that a Cray using an 80mhz cpu, and 4mb of ram can be considered 5 times the machine as one using a 200mhz cpu, with 64mb of ram.
Cray machines use a variant of Unix, and will often use resources located on other machines.

 Multics Glossary
The cray station software on Multics allowed us to use Multics as a front-end computer for the Cray.
This 7094 operating system was created at MIT Project MAC and first demonstrated in 1961.
MST Either "Multics standard tape" or "Multics system tape", which latter was in fact an instance of the former, being a checksummed, labeled, headered, trailered, fixed-length-record tape format with periodic tape marks used for all backup tapes and disk snapshots, as well as the tapes from which the system and BOS were booted.

 Cray Inc - The Supercomputer Company > Products > XT3 > Overview
The Cray XT3 Catamount microkernel runs on the compute PEs and provides a computational environment that minimizes system overhead—critical to allowing the systems to scale to thousands of processors.
All memory in the Cray XT3 system is protected with Chipkill™ technology, which increases memory reliability by two orders of magnitude when compared with standard error checking and correction (ECC) alone, enabling high memory reliability even in systems with tens of thousands of DIMMs.
Building on the success of its predecessors, the Cray T3D™ and the Cray T3E™ systems, the Cray XT3 system brings astounding new levels of scalability and sustained application performance to high performance computing (HPC).

 Future operating system direction for Cray customers
This work will ensure that the functionality and features that Cray customers currently value and use on UNICOS and UNICOS/mk systems will be available for their high-performance computing needs in the future.
The base IRIX system is a monolithic SMP UNIX system based on System V. It includes many SGI extensions for fine-grained multithreading, graphics, parallel programming, high-performance I/O, and real-time.
The rest of this document focuses on the operating system work that is needed; programming environment work is not addressed here.

 HPC Computing System Resources: Cray X1
HPC Computing System Resources: Cray X1 HPC Computing System Resources: Cray X1 The Cray X1 is a system designed with exceptional memory bandwidth, interconnect performance, and vector-processing capabilities to meet the demanding sustained computational requirements of high end computer users.
Like the CRAY T3E, the X1 employs a high speed interconnection network to provide scalability to large numbers of processors and has a directly addressable global memory with global cache coherency.
The Cray X1 implements a completely new instruction set that supports both 64- and double-speed 32-bit operations and more and larger vector registers.

 User Manual:Processing on the Cray C90:ASC Cray C90 Operating System
The interactive UNIX operating system was developed by AT&T and has been extended and enhanced at the University of California at Berkeley.
As such, it is very much like UNIX operating systems on a wide variety of other computers.
UNICOS is based on the AT&T UNIX System V with some enhancements from Berkeley UNIX (bsd 4.3).

 [No title]
The operating system is a combination of UNIX and COS functionality (COS was the Cray operating system prior to UNICOS).
In the main, a database management system is an integrated system of computer programs and files for organizing, storing, and retrieving data.
This operating system is based upon ATandT UNIX and has the Bourne and the C shells available.

 SDSC Resource Management System
The Resource Management System (Res) is a package for maintaining project allocation and usage information in a UNIX environment.
Res has been tuned to work with Cray's Unicos operating system, but the SP/AIX version exists and should work with minor modifications on non-Unicos UNIX platforms.
An example is the query of the rdb before a job submission is allowed with a queuing system (LoadLeveler, LSF, or NQE).

 SecurityTracker.com Archives - Network Queueing System (NQS) on Cray UNIX (UNICOS) Has Format String Error That Lets ...
Description: A vulnerability was reported in the Network Queueing System (NQS) daemon running on all versions of Cray's UNIX Cray Operating System (UNICOS) and possibly on some other UNIX operating systems.
SUCCESSFULLY TESTED ON ---------------------- Cray T3E running UNICOS/mk revision 2.0.5.54 HISTORY ------- The NQS, or Network Queueing System, is a popular batch software processor which is used to perform job control and leveraging in supercomputing environments which require heavy symmetric multi processing.
The author of the report notes that this vulnerability has been exploited successfully in a RISC environment, using ALPHA processors and that it may be easy to exploit on PowerPC and SPARC environments.

 WDVL: Web Databases
It runs on almost all operating systems and has been integrated into most programming languages and environments.
Deciding this depends on the natural structure of your data, and the kind of search and navigation system you want.
At the simplest end of the spectrum, if your data can be structured as a small table and you just want to retrieve records according to one or two field values, then a small custom program will suffice.
