threads. There are two kinds of service threads: those created by the operating
system or runtime system and those created by your program.
SHARE GROUP: All the processes in a control group that share the same
code. In most cases, your program has more than one share group. Share
groups, like control groups, can be local or remote.
SHARED LIBRARY: A compiled and linked set of source files that are dynamically
loaded by other executables.
SIGNALS: Messages informing processes of asynchronous events, such as
serious errors. The action that the process takes in response to the signal
depends on the type of signal and whether the program includes a signal
handler routine, a routine that traps certain signals and determines appropriate
actions to be taken by the program.
SIMD: An acronym for Single Instruction, Multiple Data, which describes a
type of parallel computing.
SINGLE PROCESS SERVER LAUNCH: A TotalView procedure that individually
launches tvdsvr processes.
SINGLE STEP: The action of executing a single statement and stopping (as if
at a breakpoint).
SISD: An acronym for Single Instruction, Single Data, which describes a
type of parallel computing.
SLICE: A subsection of an array, which is expressed in terms of a lower bound
on page 403, upper bound on page 410, and stride on page 408. Displaying a
slice of an array can be useful when you are working with very large arrays.
Compare this with a TotalView array section on page 397.
SOID: An acronym for symbol object ID. A SOID uniquely identifies all
TotalView information. It also represents a handle by which you can access
this information.
SOURCE FILE: Program file that contains source language statements.
TotalView lets you debug FORTRAN 77, Fortran 90, Fortran 95, C, C++,
and assembler files.
SOURCE LOCATION: For each thread, the source code line it executes next.
This is a static location, indicating the file and line number; it does not,
however, indicate which invocation of the subprocedure is involved.
SPAWNED PROCESS: The process created by a user process executing under
debugger control.
SPMD PROGRAMS: An acronym for Single Program, Multiple Data, which
describe a type of parallel computing that involves just one executable,
executed by multiple threads and processes.
STACK: A portion of computer memory and registers used to hold information
temporarily. The stack consists of a linked list of stack frames that
holds return locations for called routines, routine arguments, local variables,
and saved registers.
