ECG045/1097 INTEGRATION NOTE (cont.) 7... you must unload the MP drivers for all of the secondary processors, and then 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 secondary processors) (brings up the second processor in the system) (brings up the third processor in the system) (brings up the fourth processor in the system) To see which processors are on line, use MONITOR.NLM. SMP Kernel The SMP kernel support, SMP.NLM, is added to STARTUP.NCF during the installation process. The SMP kernel provides support for SMP-aware applications by coordinating the scheduling process on all active processors in the system. SMP-aware applications may be able to run on a system without the SMP kernel loaded; however, they will not realize the scaling benefit provided by the use of multiple processors in the system. Dedicated Shared Priority Boot processor is dedicated to NetWare. NetWare request from SMP aware applications are queued with requests from standard NetWare NLMs. NetWare and SMP aware applications share the boot processor. (The default mode.) Boot processor is dedicated to NetWare, but NetWare requests from SMP aware applications have priority on the boot processor over requests from standard NetWare NLMs. To change the SMP mode, use one of the SET parameters described below. SET SMP NETWARE KERNEL MODE=DEDICATED SET SMP NETWARE KERNEL MODE=SHARED SET SMP NETWARE KERNEL MODE=PRIORITY NOTE: The server is in shared mode by default unless the parameter is changed manually. Dedicated Mode Dedicated Mode should be used when you want file server response (NetWare NLMs) to be minimally affected by the SMP aware applications. The boot processor is dedicated to NetWare. Even when extra CPU time is available, SMP aware applications cannot use the boot processor to service SMP application calls. When an SMP aware application makes a NetWare call, the call will be added to the tail of the queue and serviced by the boot processor when the request reaches the front of the queue.
