Member Function Documentation

join()

TProcSet join ( const TProcSet &  ps ) const

inlinenoexcept

Construct a processor set defined by minimum of first processor and maximum of last processor in both sets

split()

void split ( const uint  n, std::vector< TProcSet > &  psets  ) const

inline

Split local processor set into n subsets of approximately the same size and return the partition in psets

Parameters

n	number of subsets to generate
psets	array to store the subsets

subset()

TProcSet subset ( const uint  i, const uint  n = 2  ) const

inlinenoexcept

Split local processor set into n subsets and return i'th subset.

Parameters

i	subset to return
n	number of subsets to split into
