The Cache panel contains information about both the RAM and Disk caches available in PFTrack.
The RAM Cache section provides control over the memory cache used to speed up playback and processing:
The size of the memory cache is shown on the left. A cache size can specified as a certain number of Mb or Gb for megabytes and gigabytes, and defaults to 50% of physical memory. It can be edited by clicking in the edit box and entering a new value.
The amount of cache used is displayed on the right. Clicking the button will clear the RAM cache.
The Disk Cache section contains information about the current disk caches available for use, and controls where new disk cached can be created.
Creating a disk cache
A new disk cache can be created by clicking the button (1).
This will open a file browser where a disk volume and directory can be choses, and add a new entry to the cache list:
After entering the cache name, clicking the button will create the cache. Alternatively the operation can be cancelled by clicking the cancel.
Managing disk caches
All available disk caches are listed (2), along with their name, the amount of space used on the disk volume, and the amount of space available to use on the right. The total amount of disk in the volume is shown at the far right.
Clicking the button will display a popup window showing the cache directory and name. The cache name can be edited from here, or the disk cache deleted if required by clicking the Delete button.
The total amount of space occupied by cached media is shown at the bottom in the Total cache indicator (3).
The System panel contains information about the CPU and GPU on the machine, as well as other useful information related to the operating system.
The CPU information section can be used to adjust the number of CPU cores being used to run multi-threaded operations in PFTrack. This will default to using All of the available CPU cores, but this can be changed to using the menu and edit boxes if required:
The GPU information section shows all the GPU cards installed in the system. The card used for displaying the PFTrack interface is indicated on the left (1), along with the card assigned for processing operations (2) such as calculating depth maps for photogrammetry.
Further information about how GPUs are used for background processing is available in the Background Processing section.
Clicking the button will display a popup window with additional information about the graphics card. Selecting the Use for processing option in this popup window will enable the graphics card for processing operations.
