NetBatch High-PIN Capabilities
NetBatch High-PIN Capabilities
NetBatch product versions D20 and later use the high PIN feature of D-series systems.
This feature allows more than 256 concurrent processes per CPU, thus removing a
limitation of the C-series system. For more information on the feature, see the
Introduction to D-Series Systems. Table 1-2 summarizes the high PIN capabilities of
NetBatch product version D30. NetBatch product versions earlier than D20 do not have
high PIN capabilities.
For more information about the high PIN capabilities of NetBatch processes, see:
12. INITIATION
ON?
If the scheduler selects a class at item 10, it checks if the class’s
INITIATION attribute is ON. If so, it goes to item 13. Otherwise, the
scheduler returns to item 10.
13. Select highest
priority job.
14. Job selected?
The scheduler attempts selection of the highest priority job from the
class selected at item 10 (not necessarily the job from item 2). If job
selection is successful, the scheduler goes to item 15. If unsuccessful
(no job selected), the scheduler returns to item 10. For information on
how the scheduler prioritizes jobs, see item 2.
15. Start job. The scheduler starts the job selected at item 9 or 14, then exits the
procedure.
