ECG045/1097 INTEGRATION NOTE (cont.) 8... Shared Mode In shared mode (the 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 shared mode, NetWare NLMs running on P0 will be more affected than when using dedicated mode. NetWare SMP Aware Applications SMP Aware Applications SMP Aware Applications P0 P1 P2 Priority Mode Priority mode is designed for a system containing eight or more processors. The boot processor is reserved for NetWare, but if an SMP aware application makes a NetWare call, that call is placed at the front of the queue and will be the next request serviced. SMP aware applications do not interrupt a NetWare task being serviced, but numerous NetWare requests from SMP aware applications queued ahead of other outstanding NetWare requests will slow down their processing. Priority mode, more than the other two modes, affects the servicing of NetWare NLMs running on P0 the most. Standard NetWare NLMs NetWare NectaWtololfaaqfrdreuodenSeutMdeP SMP Aware Applications P0 P1 P2 SMP Tips · If you are trying to run an SMP aware application, but the SMP NLMs are not loaded, the application may not load. However, some SMP aware applications, such as MSM, will load and adapt themselves to the single processor environment. · At least 64 megabytes of memory is recommended. The minimum requirement is 32 megabytes. (A minimum of 16 megabytes of main memory for each active processor is suggested.) · All intraNetWare patches should be applied before loading SMP.
