for C++ code which is doing recursive / parallelisable tasks with processor optimisation flag -xP (for an intel core duo chip) it is faster than gcc4 with optimisation for auto vectorisation and other speed optimisations At least in my case. Of course mileage might vary... I suggest its at least worth running some benchmarks so wee what differece it makes for various kinds of tasks in python. I suppose what you are really getting with the intel compiler is their know how on how best to optimise for their chips, in this case core duo... so you benefit most where there are vectorisable loops etc, which can be thrown through the SSE processor extensions. Maybe other benefits too..... just have to test i suppose... Dan Dr. Daniel James White BSc. (Hons.)
