MULTIPROCESSING

MULTIPROCESSING is a system parameter that controls the loading of the system synchronization image.

Values

0: Load the uniprocessing synchronization image SYSTEM_SYNCHRONIZATION_UNI.EXE.

1: If the CPU type is capable of SMP and two or more CPUs are present on the system, load the full-checking multiprocessing synchronization image SYSTEM_SYNCHRONIZATION.EXE. Otherwise, load the uniprocessing synchronization image SYSTEM_SYNCHRONIZATION_UNI.EXE.

2: Always load the full-checking version SYSTEM_SYNCHRONIZATION.EXE, regardless of system configuration or CPU availability.

3: If the CPU type is capable of SMP and two or more CPUs are present on the system, load the optimized streamlined multiprocessing image. On Alpha and Integrity servers, this image is SYSTEM_SYNCHRONIZATION_MIN.EXE. Otherwise, load the uniprocessing synchronization image SYSTEM_SYNCHRONIZATION_UNI.EXE. The default value is 3.

4: Always load the streamlined multiprocessing image SYSTEM_SYNCHRONIZATION_MIN.EXE, regardless of system configuration or CPU availability.

Setting the SYSTEM_CHECK parameter to 1 has the effect of setting MULTIPROCESSING to 2.
