ULimenThreadPoolDeveloperSettings

Overview

ULimenThreadPoolDeveloperSettings is a UDeveloperSettings class that allows developers to configure various parameters related to the Limen ThreadPool. It provides properties for enabling or disabling subsystem usage, automatically determining the number of threads, setting a fixed number of threads, specifying memory per thread, and defining thread priority. The settings are accessible in the Unreal Engine editor under the "Project" -> "Game" -> " Limen - Thread Pool" section.

Properties

Type	Name	Access	Description
bool	bUseSubsystem	EditAnywhere, Config	Enables or disables the use of a subsystem.
bool	bAutoDetermineThreadCount	EditAnywhere, Config	Determines if the number of threads should be automatically determined based on system capabilities.
int32	NumThreadsToUse	EditAnywhere, Config	The fixed number of threads to use when `bAutoDetermineThreadCount` is false. Must be non-negative.
int32	MemoryPerThreadInBytes	EditAnywhere, Config	The amount of memory allocated per thread in bytes. Must be non-negative.
EBP_ThreadPriority	ThreadsPriority	EditAnywhere, Config	The priority level for the threads.

Functions

Return Type	Signature	Description
int32	GetThreadCount() const	Returns the number of threads to use based on the current settings. If `bAutoDetermineThreadCount` is true, it returns the number of cores; otherwise, it returns `NumThreadsToUse`.
FName	GetContainerName() const	Returns the container name for the settings section.
FName	GetCategoryName() const	Returns the category name for the settings section.
FName	GetSectionName() const	Returns the section name for the settings section.
FText	GetSectionText() const	Returns the text representation of the section name. Only available in editor builds.
FText	GetSectionDescription() const	Returns a description of the section. Only available in editor builds.

Usage & Implementation Notes

This class is specific to Windows platforms and uses FWindowsPlatformMisc::NumberOfCores() to determine the number of threads if automatic determination is enabled.
The settings are accessible through the Unreal Engine editor, allowing developers to configure thread pool behavior without modifying code.
Memory per thread and priority can be adjusted to optimize performance based on specific use cases.
