If you're doing the modelling in ECLiPSe and that requires a lot of memory, then there may not be much left for the external solver. I ran into that with ILOG CPLEX. A partial solution is to write an ECLiPSe program that will just call the external solver and do very little else, then run that as a separate process and have them communicate. That's less convenient, but on a 32-bit machine it means you can have a basically separate 4G address space for the external solver. -- Matthew Skala, postdoctoral researcher, Universities of Toronto and Waterloo mskala_at_...203... mskala@...205... mskala@...206...Received on Sun Jul 18 2010 - 10:50:19 CEST
