Class ReDeMatMultDispatchConfigs

java.lang.Object
org.flag4j.linalg.ops.dispatch.configs.ReDeMatMultDispatchConfigs
public final class ReDeMatMultDispatchConfigs extends Object

A utility class for configuring dynamic kernel dispatch thresholds for real dense matrix multiplication.

If a configuration file ./configs/ReDeMatMult.properties is present, settings will be loaded at class initialization. If not, default values will be used. It is not generally recommended to set these values by hand.

Thread Safety:

This class is designed to be thread-safe.
