Detailed Description

Manages execution of tasks.

This class manages execution of tasks on PES. Contains host information. Also contains configuration information. Tasks are executed using this class and results are also collected with this class. So essentially this class encapsulates functionality of two sub modules. Configuration manager and task manager.

Member Function Documentation

void TaskManager::appendToStatisticsFile (    )

Append these tasks to statistics file

void TaskManager::assignInitialTasks (    )

This function assigns initial tasks to slaves.

void TaskManager::assignTask (  int    who )

This function assigns a task to PES-C with local id 'who'. This function doesn't fail even if there is no task avaliable. Then the function just sends a warning message to the console.

void TaskManager::closeFile (    )

Stub function for log File operations.

void TaskManager::closeStatisticsFile (    )

Close statistics file

virtual void TaskManager::errorShutDown (    )  [virtual]

Shuts Down the system and reports an error condition.

void TaskManager::executeTasks (    )

This function distributes tasks to PES-C's and executes them. This function is also responsible for fault checking.

virtual void TaskManager::generateTasks (    )  [virtual]

Generates tasks to be used in the program

int TaskManager::getMachineIndexFromSlave (  int    who )

Returns index of the machine, on which the slave program is running.

void TaskManager::openStatisticsFile (    )

Open statistics file

int TaskManager::packetCheck (    )

This function checks for incoming messages and gets the first message in queue. This message is processed and according changes are made.

void TaskManager::ReadFile (    )

Read Configuration File

void TaskManager::shutDown (    )

Shuts down the Task Manager. Normally only called by the destructor.

virtual void TaskManager::spawnSlaves (    )  [virtual]

This function spawns PES-S applications on the server.

void TaskManager::timeOut (  int    who )

This function signals time out of PES-C task with id 'who'.
