Unanchored Distribution Formats

Consider the following program fragment: REAL A(100),B(100) !HPF DISTRIBUTE (BLOCK(10)) :: A,B A(1:90) = B(11:100) Some have suggested that the latter case, at least, dictates a blocking factor of 10 but says nothing about relative alignment, and therefore it would be within the spirit of HPF for a compiler to choose an offset alignment such that A(1:10) and B(11:20) are mapped to the same processor, etc.
