Qualifier_Values

 

MULTIPLE_KERNEL_THREADS

   On I64 and Alpha systems, this keyword sets the MULTIPLE_KERNEL_
   THREADS bit in the dynamic segment (I64) or the image header
   (Alpha) of the image being built. This bit indicates to the image
   activator that the image can be run in a multiple kernel threads
   environment.

   If you specify this keyword for OpenVMS VAX links, it is ignored.
 

UPCALLS

   This qualifier sets the UPCALLS bit in the OpenVMS dynamic
   segment (I64) or image header (Alpha and VAX) of the image being
   built. This bit indicates to the image activator that the process
   can receive upcalls from the OpenVMS scheduler.

   When the /THREADS_ENABLE qualifier is specified without either
   the MULTIPLE_KERNEL_THREADS or UPCALLS keyword, the linker sets
   both bits by default.
