When I need most performace I use plain C++ and WMPI interface (grid) Otherwise MathLink for Excel in combination with Solver and Crystal Ball or DecisionTools from Palisade > How long do your simulations typically take to complete?

Both pages have some tutorials on using their tools. I think Excel + these add-ins are a great start for simulations (real world uses, as you said). Also a good page with tutorials is www.risk-modelling.com (both Crystal Ball and @RISK from Palisade). The URLs: www.palisade.com (Excel add-ins) www.crystalball.com (Excel add-ins) www.risk-modelling.com (tutorials for Crystal Ball and @RISK) www.criticalsoftware.com/hpc/ (commercial Grid platform for C++, works great)
