<div dir="ltr">Hi Sam,<div><br></div><div>Sorry for the delay. It's been a while since I had the time to work on this. Changing the center and width didn't work. Interestingly, changing the number of mpi processes did. I was originally using 24 processes, and it was failing when the value of bottom_id in the function get_reduce_owners() in amr_kdtree.py reached 32. </div><div><br></div><div>I did some testing, and it always worked when I used 16 processes or less. Sometimes higher numbers would work, but that depended on the input file. For instance, with one input file, it worked on 18 processes, but with a different input file, it didn't. Both the input files I tested were Flash hdf5 files, but with different levels of refinement.</div><div><br></div><div>Also, I'm not sure if this is related, but when I'm using the ipython notebook and I try to do </div><div><br></div><div>if yt.is_root()</div><div> cam.show()</div><div><br></div><div>or</div><div><br></div><div><div>if yt.is_root()</div><div> cam.snapshot()</div></div><div><br></div><div>these both cause the engines to hang. I can call cam.show() or cam.snapshot(), and they work just fine, as long as I'm calling it on all processes. But as soon as I restrict to to just root, it hangs.</div><div><br></div><div>I appreciate any help you could give me. For now, I'm just making sure to only use 16 processes, but that doesn't seem like a good long-term solution.</div><div><br></div><div>Thanks,</div><div><br></div><div>Daniel</div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">2014-11-03 15:42 GMT-05:00 Sam Skillman <span dir="ltr"><<a href="mailto:samskillman@gmail.com" target="_blank">samskillman@gmail.com</a>></span>:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi Daniel, <br><br>Could you try a different center and width argument?
