A declarative directive results in one or more declarations only; it is not associated with the immediate execution of any user code. executable directive An OpenMP directive that is not declarative. That is, it may be placed in an executable context. stand-alone directive An OpenMP executable directive that has no associated executable user code. loop directive An OpenMP executable directive whose associated user code must be a loop nest that is a structured block. associated loop(s) The loop(s) controlled by a loop directive. COMMENT: If the loop directive contains a collapse clause then there may be more than one associated loop. construct An OpenMP executable directive (and for Fortran, the paired end directive, if any) and the associated statement, loop or structured block, if any, not including the code in any called routines. That is, in the lexical extent of an executable directive. region All code encountered during a specific instance of the execution of a given construct or of an OpenMP library routine. A region includes any code in called routines as well as any implicit code introduced by the OpenMP implementation. The generation of a task at the point where a task directive is encountered is a part of the region of the encountering thread, but the explicit task region associated with the task directive is not. The point where a target or teams directive is encountered is a part of the region of the encountering thread, but the region associated with the target or teams directive is not. COMMENTS: A region may also be thought of as the dynamic or runtime extent of a construct or of an OpenMP library routine. During the execution of an OpenMP program, a construct may give rise to many regions. active parallel region A parallel region that is executed by a team consisting of more than one thread. inactive parallel region A parallel region that is executed by a team of only one thread. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32
