<p> it seems that the F77 and FC environment variables are different. I want to use (=/scratch1/g0306332/intel/fc/bin/ifort). How can I configure them?</p>

<p> If I use the lammpi which the sch provide, I got this error msg:</p>

</div>
<div> </div>
<div>I also replace <a onclick="return top.js.OpenExtLink(window,event,this)" href="http://libmpi.la/" target="_blank">libmpi.la</a> with libmpi.a but both cannot work.</div>
<div> </div>
<p>Shared libraries cannot be built using MPI provided.<br>Either rebuild with --with-shared=0 or rebuild MPI with shared library support<br> </p>
<div>What's the extension for shared libraries for ia64 platform? Is it *.so? </div>
<p> </p>
<p>thanks alot</p></div>
