A list of terms used consistently throughout the Gist manuals.
- A point in a parallel program, designated by the
programmer by a call to the
function. (Note that this differs from the meaning of
event in the SGI
man perfex documentation.)
- The process of adding Gist calls to a parallel
program and linking with LibGist.
- A quantity measured by the hardware or operating system, such
as the number of clock cycles, floating point operations,
cache misses, or page faults. (Note that performance measures
are called "events" in the SGI
PID / Processor identifier.
- The term PID is used throughout this documentation to
denote the programmer's idea of which processor
executes an instruction. LibGist does not make any effort
to determine which processor it is running on. Thus the PID
may actually be a thread ID or any other integer identifier
(but see Logging
- The interval between two specified events. A processor is
understood to be in a given state only when the two events
occur consecutively on the processor, with no intervening
