	)

This function actually does the RCM ordering of a symmetric csr matrix (entire) The original implementation can be found in src/parcsr_ls/par_ilu.c in hypre.

Parameters

[in]	offsets	row offsets in the matrix to reorder
[in]	columns	column indices in the matrix to reorder
[in]	rankOffset	offset of this rank (assuming numComps = 1)
[out]	perm	the permutation array
