Detailed Description

template<class EOT>
struct eo::mpi::ParallelApplyData< EOT >

Data useful for a parallel apply (map).

A parallel apply needs at least the functor to apply to every element of the table, and the table itself, whereas it can be set later with the function init(). Master rank is also needed, to send it informations and receive informations from it, inside the functors (the job knows these values, but the functors don't). The size of a packet can be tuned here.

Internal attributes contain:

  • (useful for master) the index of the next element to be evaluated.
  • (useful for master) a map containing links between MPI ranks and slices of the table which the worker with this rank has evaluated. Without this map, when receiving results from a worker, the master couldn't be able to replace the right elements in the table.

Constructor & Destructor Documentation

template<class EOT >
eo::mpi::ParallelApplyData< EOT >::ParallelApplyData ( eoUF< EOT &, void > &  _proc,
int  _masterRank,
int  _packetSize,
std::vector< EOT > *  table = 0 
) [inline]

Ctor for Parallel apply (map) data.

_procThe functor to apply on each element in the table
_masterRankThe MPI rank of the master
_packetSizeThe number of elements on which the function will be applied by the worker, at a time.
tableThe table to apply. If this value is NULL, user will have to call init() before launching the job.
