) allows you to add additional processors to a system without adding the overhead of an entire machine with its own hardware (disk drives and network cards) and software (operating system and disk drivers). An SMP server also allows a network administrator to centralize network services- file, print - HP ProLiant 4500 | intraNetWare Symmetric Multiprocessing - Page 4
from peripheral boards, timers, or other components. The Systempro/XL and ProLiant family were the first Compaq SMP servers and used the 8259 programmable interrupt controller. This architecture is symmetric: any processor can service any interrupt and there are separate Direct Memory Access (DMA - HP ProLiant 4500 | intraNetWare Symmetric Multiprocessing - Page 5
are the Platform Support Module (PSM) and the MP driver. The MP driver activates the secondary processors (processors beyond the boot processor). The PSM is provided by the hardware vendor in order for the SMP kernel to communicate with the processors. The PSM that Compaq supplies for intranetWare - HP ProLiant 4500 | intraNetWare Symmetric Multiprocessing - Page 6

After installation is complete, down and restart the server. MP Driver During installation, the following commands are - HP ProLiant 4500 | intraNetWare Symmetric Multiprocessing - Page 7
load the MP driver for the selected processors. For example, if there are four processors in a system, the MP driver may be loaded for any of the three secondary processors using the following commands: UNLOAD MPDRIVER LOAD MPDRIVER 1 LOAD MPDRIVER 2 LOAD MPDRIVER 3 (unloads SMP support for all - HP ProLiant 4500 | intraNetWare Symmetric Multiprocessing - Page 8
default mode), both NetWare and SMP aware applications use the boot processor. This mode should be used when the file server activity does not need priority service and the SMP aware application could benefit from more processing power. CPU time is distributed on a first come, first served basis. In - HP ProLiant 4500 | intraNetWare Symmetric Multiprocessing - Page 9

SMP aware threads need locks to ensure the integrity of an operation being serviced. For example, the Mutex list may be locked temporarily by an SMP the secondary processors.
