* This is the header file for the OpenMP 4.5+ implementation of the
|
|
* NVECTOR module.
|
|
*
|
|
* Notes:
|
|
*
|
|
* - The definition of the generic N_Vector structure can be found
|
|
* in the header file sundials_nvector.h.
|
|
*
|
|
* - The definition of the type 'realtype' can be found in the
|
|
* header file sundials_types.h, and it may be changed (at the
|
|
* configuration stage) according to the user's needs.
|
|
* The sundials_types.h file also contains the definition
|
|
* for the type 'booleantype'.
|
|
*
|
|
* - N_Vector arguments to arithmetic vector operations need not
|
|
* be distinct. For example, the following call:
|
|
*
|
|
* N_VLinearSum_OpenMPDEV(a,x,b,y,y);
|
|
*
|
|
* (which stores the result of the operation a*x+b*y in y)
|
|
* is legal.
