I'm just forwarding the exchange i had with Zhang to the list as I
hit the wrong reply button again and left out the list.<br>
<br>
Zhang, what mpi library did you build with? Are you sure mpi works
properly on your machine? <br>
<br>
I wonder if this is the same problem i had once on a CentOS cluster
with Intel Xeons and FLASH3.2, where it would segfault before it
even reached call Drivier_initFlash() in Flash.F90. Our sys admin
couldn't solve the problem either, but we had another cluster to
work on, so we dropped the issue. That being said, it really should
work, though.<br>
<br>
Best wishes,<br>
Alex<br>

<div>Hi Zhang,</div>
<div><br>
</div>
<div>The developers will need more information than this to help
you.</div>
<div><br>
</div>
<div>What problem are you trying to run? (Have you tried any of
the test problems supplied?)</div>
<div>What machine are you running on?</div>
<div>What version of FLASH?</div>
<div>How did you compile the code?</div>
<div>Were any logfiles generated?</div>
<div><br>
</div>
<div>To find out where the code is crashing, you may want to run
it in a debugger.</div>
<div><br>
</div>
<div>Best wishes,</div>
