[ODE] ODE slow on itanium?

Hi All,

I've just been doing some benchmarking of my simulation on various  
processors and they all behave about as I expect except for a truly  
dreadful showing on a recent 1.6GHz Itanium system. It's over 3 times  
slower than an Opteron 252 which is hardly cutting edge anymore, and  
over twice as slow as the Xeon 5160 in my MacPro. They are all  
compiled with gcc using the standard "-O3 -ffastmath" options. Anyone  
got any idea what's wrong since I don't think the Itanium should be  
this slow...
