<div dir="ltr">Hi Frank, Erik, and Roland.<div><br></div><div>Thanks for your tips. After many hours of looking into this problem, and even trying (unsuccessfully) to use Carpet macros, I conclude that I am being held back by a bug in Cactus scheduling.</div><div><br></div><div>I have created a very simple thorn called ScheduleTester that demonstrates what I believe to be a bug in Cactus scheduling. Since it is 100% reproducible using this thorn, I have created a bug report (ET Trac #1778) with the thorn attached. I have also attached the thorn to this email. Inside the tarball, you'll find the 2015_05 ET release ThornList, with this thorn included, as well as a .par file in the par/ directory that will reproduce the bug.</div><div><br></div><div>Thanks in advance for helping to take a look at this thorn, and have a great weekend!</div><div><br></div><div class="gmail_extra"><div><div><div dir="ltr"><div>-Zach</div><div><br></div>* * *<br>Zachariah Etienne<br>Assistant Professor of Mathematics<div>West Virginia University<br></div></div></div></div>

</span>I forgot to mention that one other requirement we had was that we wanted<br>
to reuse the temporary variables needed for the reductions. So, first<br>
doing all local computations and then reducing all of them wouldn't<br>
work. Some of that might have been the reason to move to ANALYSIS too, I<br>
don't remember.<br>
