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)
