I see what you mean. I could really have made use of a cluster a few months ago. I ran 10 models on 4 computers in parallel for the better part of a week. It was a bit complicated copying files making sure not to overwrite an estimated model, because I used Macintoshes, at least I benefited from the reliability and uptime of UNIX. And many thanks to Michael Blasnik for -estsave-. Without it it ... I don't know what I would have done.

although I heard that Stata Corp. has been looking into
multithreading some of  their code.
That's interesting. If you a right then I hope they will focus on -gllamm- related code. This could mean a considerable performance boost for anyone with a dual or multiprocessor system.
