Detailed Description

Class for doing Pythia runs in parallel.

Constructor & Destructor Documentation

PythiaParallel	(	string	xmlDir = "../share/Pythia8/xmldoc",
		bool	printBanner = true
	)

Constructor.

The PythiaParallel class.

Contructor.

Member Function Documentation

void foreach

(

function< void(Pythia *)>

action

)

Perform the specified action for each Pythia instance.

Perform action in serial.

void foreachAsync

(

function< void(Pythia *)>

action

)

Perform the specified action for each instance in parallel.

Perform action in parallel.

bool init

(

function< bool(Pythia *)>

additionalSetup

)

Initialize error printing.

Read settings.

Set seeds.

Create instances in parallel.

Wait for all initialization threads to finish.

Set initialization.

Print warning message and return.

bool readFile	(	string	fileName,
		bool	warn = true,
		int	subrun = SUBRUNDEFAULT
	)

Read in updates for settings or particle data from user-defined file.

Hand over real work to next method.

void stat

(

bool

combine = true

)

Write final statistics, combining errors from each Pythia instance. For all PhysicsBase objects, combine that PhysicsBase object across all threads, if onStat is defined for that specific PhysicsBase type.

Loop through all PhysicsBase-derived objects.

Check the PhysicsBase objects are consistent.

Push back the PhysicsBase object.

Print the stats.
