NEC SX

[6] Since the SX-4, SX series supercomputers are constructed in a doubly parallel manner.

[11] Starting in 2001, Cray marketed the SX-5 and SX-6 exclusively in the US, and non-exclusively elsewhere for a short time.

[15] Tadashi Watanabe has been NEC's lead designer for the majority of SX supercomputer systems.

Some vertical applications are available through NEC, but in general customers are expected to develop much of their own software.

In addition to commercial applications, there is a wide body of free software for the UNIX environment which can be compiled and run on SUPER-UX, such as Emacs, and Vim.

[19] The VE operating system VEOS runs in user space on the VH.

Applications compiled for the VE can use almost all Linux system calls, they are transparently forwarded and executed on the VH.
