Implicitly Included Flags

This section contains descriptions of flags that were included implicitly by other flags, but which do not have a permanent home at SPEC.


System and Other Tuning Information

Platform settings

One or more of the following settings may have been set. Please see the Notes section of the report to determine which, if any, have been modified.

Adjacent Sector Prefetch (Default: Workstations=Disabled, Servers=Enabled):

This BIOS option allows the enabling/disabling of a processor mechanism to fetch the adjacent cache line within an 128-byte sector that contains the data needed due to a cache line miss.

In some limited cases, setting this option from the Default may improve performance. In the majority of cases, the default setting provides better performance. Users should modify this option after performing application benchmarking to verify improved performance in their environment.

Hardware Prefetch (Default = Enabled):

This BIOS option allows allows the enabling/disabling of a processor mechanism to prefetch data into the cache according to a pattern recognition algorithm.

In some limited cases, setting this option to Disabled may improve performance. In the majority of cases, the option set to Enabled provides better performance. Users should only disable this option after performing application benchmarking to verify improved performance in their environment.


Flag description origin markings:
