Package org.apache.sysds.resource

Class ResourceCompiler

java.lang.Object

org.apache.sysds.resource.ResourceCompiler

public class ResourceCompiler
extends Object

This class does full or partial program recompilation based on given runtime program. It uses the methods provided by hops.recompile.Recompiler). It keeps a state of the current recompilation phase in order to decide when to do full recompilation and when not.

doFullRecompilation

public static Program doFullRecompilation(Program program)

Recompiling a given program for resource optimization. This method should always be called after setting the target resources to InfrastructureAnalyzer and SparkExecutionContext

Parameters:

program - program to be recompiled

Returns:

the recompiled program as a new Program instance

setSingleNodeResourceConfigs

public static void setSingleNodeResourceConfigs(long nodeMemory,
 int nodeCores)

Sets resource configurations for executions in single-node mode including the hardware configurations for the node running the CP.

Parameters:

nodeMemory - memory budget for the node running CP

nodeCores - number of CPU cores for the node running CP

setSparkClusterResourceConfigs

public static void setSparkClusterResourceConfigs(long driverMemory,
 int driverCores,
 int numExecutors,
 long executorMemory,
 int executorCores)

Sets resource configurations for executions in hybrid mode including the hardware configurations for the node running the CP and the worker nodes running Spark executors

Parameters:

driverMemory - memory budget for the node running CP

driverCores - number of CPU cores for the node running CP

numExecutors - number of nodes in cluster

executorMemory - memory budget for the nodes running executors

executorCores - number of CPU cores for the nodes running executors
