NEC SX

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

[citation needed] These nodes are then installed in a regular SMP arrangement.

[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.
