Detailed Description

A one-shot service that simulates a CPU-bound thread that performs a given number of flops and then reports to some mailbox saying "I am done".

Constructor & Destructor Documentation

◆ ComputeThread()

wrench::ComputeThread::ComputeThread	(	std::string	hostname,
		double	flops,
		std::string	reply_mailbox
	)

Constructor.

Parameters

hostname	the host on which the compute thread should run
flops	the number of flops to perform
reply_mailbox	the mailbox to which the "done/failed" message should be sent

Member Function Documentation

◆ cleanup()

void wrench::ComputeThread::cleanup	(	bool	has_returned_from_main,
		int	return_value
	)

overridevirtual

Cleanup method that overrides the base method and does nothing as a compute thread does not need to implement any particular fault-tolerant behavior (it runs on the same how as a workunit executor, which is also dead anyway)

Parameters

has_returned_from_main	whether the daemon has terminated cleanly (i.e., returned from main)
return_value	main's return value

Reimplemented from wrench::S4U_Daemon.

◆ main()

int wrench::ComputeThread::main ( )

overridevirtual

The main method of the compute thread.

Returns

Implements wrench::S4U_Daemon.
