Dear all, I'm working on a very complex linear optimization problem using the lp.transport function in lpSolve. My PC has 10 cores, but by default R uses only one of them. Is there a straightforward way to make lp.transport use all cores available? I had a look at "High-performance and parallel computing in R" ( http://cran.r-project.org/web/views/HighPerformanceComputing.html), but I have the impression that using multiple cores would require me to change the function underlying lp.transport. The problem is that I'm not able whether I'm able to make those adjustments. Thanks, Michael [[alternative HTML version deleted]]
