Hi,<BR>
<BR>
Altix is yet another platform we haven't been able to test ourselves, <BR>
so please test the new release candidate for 3.3 and report any <BR>
compile or runtime errors (preferrably through <A HREF="http://">http://</A><BR>
bugzilla.gromacs.org).<BR>
<BR>
There are both single and double precision Itanium2 loops that <BR>
hopefully should work.<BR>
<BR>
Cheers,<BR>
<BR>
Erik<BR>
