7.10 Synchronization

The following routines automatically force synchronization of the processors in when called from global HPF routines:

These routines do not force synchronization when called from EXTRINSIC(HPF_LOCAL) and EXTRINSIC(HPF_SERIAL) routines.

Synchronization of processors can have an effect on performance. Therefore, it is preferable to avoid synchronization of the processors in the computationally intensive kernel of a program.
