I have come across problems before with certain versions of the Intel
compilers and the QM/MM code on Altix. The issue has been with the compiler
misvectorizing loops. A couple of things to check before we dig any deeper.
1) Have you applied all the lastest bugfixes and made clean / recompiled?
There are several workarounds in these bugfixes to address certain intel
compiler bugs.
2) Is this running in serial or in parallel?
Please take a look at the following page:

and see if the suggestions in here fix the problem.
All the best
Ross
