Because the previous PR #6440 had an unresolved issue that was blocking the merge, I have now split the PR into several smaller PRs and resubmitted them
This pull request addresses issue #6377
A temporary variable
DM2D_tmpwas created to split the 2D block parallelDM2Dinto smaller blocks. The functiontransferParallels2Serialsis directly called to convertDM2D_tmpintoDMRGint[]. This approach avoids the large memory consumption that would occur if a large matrixDMRGint_fullwas first used to holdDM2Dand then split into smaller matricesDMRGint.
