Function documentation

void walker::Distributor::registered()

Reduction target indicating that all Integrator chares have registered with the statistics merger (collector)

This function is a Charm++ reduction target that is called when all Integrator chares have registered with their local branch of the statistics merger group, Collector. Once this is done, we issue a broadcast to all Itegrator chares to continue with their setup.

void walker::Distributor::estimateOrd(tk::real* ord, int n)

Estimate ordinary moments.

Parameters
ord in	Ordinary moments (sum) collected over all chares
n in	Number of ordinary moments in array ord

void walker::Distributor::estimateCen(tk::real* cen, int n)

Estimate central moments.

Parameters
cen in	Central moments (sum) collected over all chares
n in	Number of central moments in array cen

void walker::Distributor::estimateOrdPDF(CkReductionMsg* msg)

Estimate ordinary PDFs.

Parameters
msg in	Serialized vectors of uni-, bi-, and tri-variate PDFs

void walker::Distributor::estimateCenPDF(CkReductionMsg* msg)

Finish estimation of central PDFs.

Parameters
msg in	Serialized vectors of uni-, bi-, and tri-variate PDFs

void walker::Distributor::nostat()

Charm++ reduction target enabling shortcutting sync points if no stats.

This reduction target is called if there are no statistics nor PDFs to be estimated and thus some synchronization points can be skipped. Upon this call we simply finish up the time step as usual.
