MIPS region of a TNS object file

The region of a TNS object file that contains MIPS instructions and the tables necessary to execute

the instructions in accelerator mode on a TNS/R system. Accelerator creates this region and writes

it into the TNS object file. Contrast with Intel Itanium instruction region.

MIPS RISC instructions

and directly executed on TNS/R systems. MIPS RISC instructions do not execute on TNS systems

and TNS/E systems. Contrast with TNS instructions and Intel Itanium instructions.

Accelerator-generated MIPS RISC instructions are produced by accelerating TNS object code.

Native-compiled MIPS RISC instructions are produced by compiling source code with a TNS/R

native compiler.

MIPS RISC word

An instruction-set-defined unit of memory. A MIPS RISC word is 4 bytes (32 bits) wide, beginning

on any 4-byte boundary in memory. Contrast with TNS word and word. See also Intel Itanium

word.

mirrored disk or volume

A pair of identical disk drives that are used together as a single logical volume. One drive is

considered primary, and the other is called the mirror. Each byte of data written to the primary

drive is also written to the mirror drive. If the primary drive fails, the mirror drive can continue

operations. See also volume.

missed address file (MAF)

A file used by the NonStop operating system during memory caching operations.

MMF PIC

See multimode fiber-optic (MMF) plug-in card (PIC).

MMF ServerNet cable

Maintenance orchestrator.

mode

The set of attributes that specify the type and access permissions for a file. See also file mode.

modular cabinet

A cabinet with an integrated 19-inch rack equipped with a power distribution unit (PDU), doors,

slides, brackets, castors, leveling pads, and optional side panels. See also cabinet.
