Hi John,

Both of your examples worked just fine on my machine.  Only minor modifications to the makefiles to export the correct path.  Thanks to both Statler and Waldorf for your hard work on this.  I'll have another go at the demo that I was working on in Seattle. Otherwise I got similar nonlinear run times as the number of threads increased.  Also, hessian calculations are not multithreaded, right?

I've shared an item with you.

Multi-threading has be an ADMB development priority for quite a while. Dave Fournier has made lot of progress over the last year and some prelminary results were presented in the June ADMB developer workshop in Seattle. This document provides a more rigorous assessment of the efficacy of using pthreads in ADMB models. The results show that there is a considerable performance advantage in multi core machines.

The current version of the code is available for checkout on the ADMB Subversion server svn+ssh://admb-project.org/branches/threaded2 Please give it a try. If nobody wants to test it, why are we doing it?

Cheers (and apologies for double posting),
John
