Data Cache Dialog¶
The Data Cache dialog is accessed via the Main Menu > Options > Data Cache Options… menu item.
It lets you customize the memory usage of SEQUOIA, including the Data Caching and Out Of Core memory managemen.
The Data Cache¶
SEQUOIA will attempt to cache any results of long data processing like point and mesh data.
When an Object is being updated and all its relevant parameters match an existing Cache record, the cached data will be loaded instaneneously instead of performing a lengthly calculation again.
The Out Of Core Memory Manager¶
When certain operations like point data file conversion require more memory than is available in the system RAM, SEQUOIA will use the hard disk drives to extend the memory space.
While this is slower than using Physical Memory, it is significantly more efficient than relying on the OS Swap File.
Controls¶
Max.Size (% of Physical Memory)¶
Defines the maximum amount of physical memory expressed as Percentage to use for Data Caching.
If set to 0, no Data Caching will be performed.
Current Size¶
This field displays the current memory usage of the Data Cache.
Physical Memory¶
This field displays the currently available Physical Memory to consider when calculating the Percentage.
Out Of Core Size (% of Physical Memory)¶
Defines the memory threshold for using Out Of Core calculations vs. In Core.
When the the memory requirements of the task exceed this threshold, Out Of Core calculations will be performed.
Out Of Core Workspace Files¶
The list shows the workspace files and their paths to be used by the Out Of Core memory manager.
New workspace files can be added by clicking the [Add…] button to pick a file name and path on a fast HDD or SSD drive.
Existing entries can be removed by selecting from the list and pressing the [Remove] button.
Consider using the fastest local drive for Out Of Core memory management.
