Class ConfigurationManager

java.lang.Object

org.apache.sysds.conf.ConfigurationManager

public class ConfigurationManager
extends Object

Singleton for accessing the parsed and merged system configuration. NOTE: parallel execution of multiple DML scripts (in the same JVM) with different configurations would require changes/extensions of this class.

Method Detail

getCachedJobConf

public static org.apache.hadoop.mapred.JobConf getCachedJobConf()

Returns a cached JobConf object, intended for global use by all operations with read-only access to job conf. This prevents to read the hadoop conf files over and over again from classpath. However,

Returns:

the cached JobConf

setCachedJobConf

public static void setCachedJobConf(org.apache.hadoop.mapred.JobConf job)

setGlobalConfig

public static void setGlobalConfig(DMLConfig conf)

Sets a global configuration as a basis for any thread-local configurations. NOTE: This global configuration should never be accessed directly but only through its thread-local derivatives.

Parameters:

conf - the configuration

setLocalConfig

public static void setLocalConfig(DMLConfig conf)

Sets the current thread-local dml configuration to the given config.

Parameters:

conf - the configuration

getDMLConfig

public static DMLConfig getDMLConfig()

Gets the current thread-local dml configuration.

Returns:

the dml configuration

setGlobalConfig

public static void setGlobalConfig(CompilerConfig conf)

setLocalConfig

public static void setLocalConfig(CompilerConfig conf)

Sets the current thread-local compiler configuration to the given config.

Parameters:

conf - the compiler configuration

clearLocalConfigs

public static void clearLocalConfigs()

Removes the thread-local dml and compiler configurations, leading to a reinitialization on the next get unless set in between.

getCompilerConfig

public static CompilerConfig getCompilerConfig()

Gets the current thread-local compiler configuration.

Returns:

the compiler configuration

getCompilerConfigFlag

public static boolean getCompilerConfigFlag(CompilerConfig.ConfigType key)

Get a boolean compiler config in a robust manner, returning false if config not existing.

Parameters:

key - config type

Returns:

compiler config flag

getScratchSpace

public static String getScratchSpace()

getBlocksize

public static int getBlocksize()

isDynamicRecompilation

public static boolean isDynamicRecompilation()

isParallelMatrixOperations

public static boolean isParallelMatrixOperations()

isParallelParFor

public static boolean isParallelParFor()

isCodegenEnabled

public static boolean isCodegenEnabled()
