INITIALIZATION FILE: An optional file that establishes initial settings for
debugger state variables, user-defined commands, and any commands that
should be executed whenever TotalView or the CLI is invoked. Must be
called .tvdrc.
INTERPRETER: A program that reads programming language statements and
translates the statements into machine code, then executes this code.
LAMINATE: A process that combines variables contained in separate processes
or threads into a unified array for display purposes.
LHS EXPRESSION: This is a synonym for lvalue.
LINKER. A program that takes all the object files creates by the compiler and
combines them and libraries required by the program into the executable
program.
LOCKSTEP GROUP: All threads that are at the same PC (program counter).
This group is a subset of a workers group. A lockstep group only exists for
stopped threads. All threads in the lockstep group are also in a workers
group. By definition, all members of a lockstep group are in the same workers
group. That is, a lockstep group cannot have members in more than
one workers group or more than one control group.
LOOP, INFINITE: see infinite loop on page 402.
LOWER BOUND: The first element in the dimension of an array or the slice of
an array. By default, the lower bound of an array is 0 in C and 1 in Fortran,
but the lower bound can be any number, including negative numbers.
LVALUE: A symbol name or expression suitable for use on the left-hand
side of an assignment statement in the corresponding source language.
That is, the expression must be appropriate as the target of an assignment.
MACHINE STATE: Convention for describing the changes in memory, registers,
and other machine elements as execution proceeds.
MANAGER THREAD: A thread created by the operating system. In most
cases, you do not want to manage or examine manager threads.
MESSAGE QUEUE: A list of messages sent and received by message-passing
programs.
MIMD: An acronym for Multiple Instruction, Multiple Data, which describes
a type of parallel computing.
MISD: An acronym for Multiple Instruction, Single Data, which describes a
type of parallel computing.
MPI: An acronym for “Message Passing Interface.”
MPICH: MPI/Chameleon (Message Passing Interface/Chameleon) is a freely
available and portable MPI implementation. MPICH was written as a collaboration
between Argonne National Lab and Mississippi State University. For
more information, see http://www.mcs.anl.gov/mpi.
MPMD PROGRAMS: An acronym for Multiple Program, Multiple Data, which
describes programs that involve multiple executables, executed by multiple
threads and processes.
