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

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

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
