HPMIXED =/= HPLMIXED
HPMIXED used sparse matrix techniques to accelerate computing but no multi-
threading/multi-core technology are utilized, and it only deals with a very
restrictied class of linear mixed models, mostly a block-diagonal cov-
matrix which is able to use sparse matrix computing to the max power.
While I haven't seen any details of HPLMIXED, I believe it is able to
handle linear mixed models with richer type of cov-matrix and has mutli-
threading/distributed-computing technology embedded.
