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.
