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.
