I posted about two months back about single precision gromacs 3.2.1 on 
an Altix 3700B running pretty dismally - slower than a new Dell 
Dimension Pentium 4. That gromacs version doesn't have optimized inner 
loops for Itanium 2 chips, but current CVS versions do & the speedup on 
single precision was appreciable. Both single and double versions of 
3.3beta CVS versions work on the machine I use. I'd suggest getting a 
version upgrade and hoping the problem goes away :-)
