New Cosmos Solvers and Dual CPU's

The new solvers for Cosmos/M, CosmosWorks and DesignStar are all meant to utilise miltiple processors when available. I have been using them for a couple of weeks and I don't think they do. I have a dual CPU machine but when NSTAR, ASTAR or STAR are running they will only ever use a maximum of 50% of the processing power of my PC. This is the same as when I use any other Windows program.

Has anyone got more than 50% CPU usage with dual processors running the new solvers?

(My machine is a dual Xeon windows XP Pro running the latest version of DesignStar and Cosmos 2003)

Only FFEPlus supports 2 processors workstations. Read 'Whats new' on cosmos website.

And it is really the sparse solver and skyline solver that need it. It is these solvers that get called to do the really dirty slow work when running non-linear or dynamic models.

The "what's new" articles all say that the solvers support multiple processors, but I have not seen them using any more than 50% of my 2 processors, which is the same as using 1 processor.

Has anyone got a dual cpu machine and had a look to see if the solvers use them both?
