   Hi everyone, I want to know if somebody can help me with this: A
methodology to increase the performance of R to achieve the convergence in
lmer or nlme moldels.

   Actually even if the computer presents more than one core I have read
that R works with only one of them. Also I have read about the existence of
packages (Eg. parallel) that can improve the speed of the computer. This is
based in using all the cores of the pc, but I think this works for
independent functions and it does not optimize only one process like in the
case of the linear mixed model.

Thanks for your help guys,

Regards
Felipe.
