Tandem Computers Inc’s hot new NonStop Kernel microkernel, which will run on its forthcoming MIPS Technologies Inc RISC-based Himalaya fault-tolerant systems (CI No 2,213), is not derived from the Chorus Systemes SA Chorus/Mix Unix microkernel – which Tandem is also working with – but has been developed out of the Cupertino, California firm’s proprietary Guardian operating system. It is a complete re-write, the company says. Guardian and Unix personalities will run on top of the NonStop Kernel. Tandem says the Unix personality is not a version of its NonStop-UX Unix System V.4 implementation which runs on its Integrity systems, which has been enhanced to prevent system panics. Rather it is a collection of application programming interfaces, including Posix and other extensions, the Open Software Foundation’s Distributed Computing Environment, and a NonStop Tuxedo transaction processing monitor being developed in conjunction with Unix System Laboratories: Tandem’s own Pathway transaction processing monitor will also figure in there, the company says. The Tuxedo and DCE technology will be available by mid-1994. The Unix personality has been designed to enable Unix System V.4 software developed on third-party workstations Tandem does not recommend its systems for application development as such – to run on the new Himalaya machines. As last week’s announcement is part of Tandem’s the long-term plan to coalesce its two fault-tolerant lines, the company says it hopes that all customers will in future target new application development at the Unix personality and not Guardian. Tandem is working alongside Unix Labs to enhance the scalability and resiliance of the Chorus microkernel for commercial applications, it says. Tandem has already said it will offer Microsoft Corp Windows NT on its Integrity line sometime next year – it now says it will likely offer an NT personality on the Himalayas along with others too, like the IBM Corp-Apple Computer Inc object-oriented Taligent system, formerly known as Pink. The Himalayas – K100, K1000 and K10000 – use MIPS R3000, R3000 and R4400 RISCs respectively and are priced at from $25,000 at the low-end and $340,000 at the top. The massively parallel K10000 – Tandem’s largest ever machine – uses from 16 to 4,080 150MHz MIPS R4400 RISCs. TorusNet nodes, with 16 CPUs, can be linked together to produce a 224-node TorusNet Domain. String those together for multi-domains with up to 4,080. The 16-way system has 64 input-output channels, a 4,080-processor monster will come with 16,320. Maximum main memory supported goes from 4Gb to 1Tb – and 12Tb to 30Pb of disk.
