What do "high performance computer resources" mean to you? Probably Stata/MP? If so, the authors of the command probably need to make an effort to take advantage of several processors. Official Stata`s -xtmixed- does not seem to benefit from multiple processors, though: See http://www.stata.com/statamp/report.pdf, page 112. Probable reason: Its code is not amenable to parallelization. The same may well apply to -gllamm-. HTH Martin
