Ah, OK.

Just drop me a note when a regular test including Ada starts to be 
useful (I probably have to skip some other front end language in favor 
Ada to stay within the two hour elapsed time window between two weather 
forecasting runs).

BTW, the ultimate reason I asked was that it turned out that running an 
ordinary quad core PC to the max doesn't come for free.

Last month I got past year's electricity bill - it turns out that I am 
now (16 hours of weather forecasting and 4 hours of GCC bootstrapping 
per day) using 3200 KWh a year - to the tune of 1100 Euros.

So the question whether a run is useful is certainly relevant :-)
