explicitly parallel instruction set computing (EPIC)
explicitly parallel instruction set computing (EPIC). A processor architecture in which
the instruction stream encodes what can be done in parallel (so that the hardware
need not do this). Compare to complex instruction set computing (CISC) and reduced
instruction set computing (RISC).
high PIN. A process identification number (PIN) that is greater than 255. Compare to low
PIN.
HP Transaction Application Language (TAL). A high-level, block-structured language
used to write system software and transaction-oriented applications on NonStop
operating systems.
indirection symbol. One of the following:
low PIN. A process identification number (PIN) in the range 0 through 254. Compare to high
PIN.
native. An adjective that can modify object code, object file, process, procedure, and mode
of process execution. Native object files contain native object code, which directly uses
MIPS or Intel® Itanium® instructions and the corresponding conventions for register
handling and procedure calls. Native processes are those created by executing native
object files. Native procedures are units of native object code. Native mode execution
is the state of the process when it is executing native procedures.
native compiler. In the context of this manual, the pTAL compiler or EpTAL compiler.
native mode. The operational environment in which Itanium and native-compiled RISC and
Itanium instructions execute. Compare to TNS accelerated mode and TNS mode.
native object code. See TNS/R native object code or TNS/E native object code.
native object file. A TNS/R native object file or a TNS/E native object file.
native process. See TNS/R native process or TNS/E native process.
OCA. See TNS Object Code Accelerator (OCA).
