Glossary

absolute pathname. An Open System Services (OSS) pathname that begins with a

slash (/) character and is resolved beginning with the root directory. Contrast with

relative pathname.

accelerate. To speed up emulated execution of a TNS object file by applying the

Accelerator for TNS/R system execution or the Object Code Accelerator (OCA) for

TNS/E system execution before running the object file.

accelerated mode. See TNS accelerated mode.

accelerated object code. The MIPS RISC instructions (in the MIPS region) that result from

processing a TNS object file with the Accelerator or the Intel® Itanium® instructions (in

the Itanium instruction region) that result from processing a TNS object file with the

Object Code Accelerator (OCA).

accelerated object file. A TNS object file that, in addition to its TNS instructions (in the

TNS region) and symbol information (in the symbol region), has been augmented by

the Accelerator with equivalent but faster MIPS RISC instructions (in the MIPS region),

the Object Code Accelerator (OCA) with equivalent but faster Intel® Itanium®

instructions (in the Itanium instruction region), or both.

Accelerator. A program optimization tool that processes a TNS object file and produces an

accelerated object file that also contains equivalent MIPS RISC instructions (called the

MIPS region). TNS object code that is accelerated runs faster on TNS/R processors

than TNS object code that is not accelerated. See also TNS Object Code Accelerator

(OCA).

Accelerator region of an object file. The region (called the MIPS region) of an object file

that contains MIPS RISC instructions and tables necessary to execute the object file

on a TNS/R system in accelerated mode. The Accelerator creates this region. Contrast

with OCA region of an object file. See also accelerated object file.

address space. The memory locations to which a process has access.

AXCEL. The command used to invoke the Accelerator on a TNS/R or TNS/E system.

central processing unit (CPU). Historically, the main data processing unit of a computer.

HP NonStop™ servers have multiple cooperating processors rather than a single CPU.
