In some cases, it get stuck for hours that I don’t know if it will ever finish. I’ve tracked down the bottleneck to be the `annotate_contour` method. The server should be faster than my local machine. (I’m not exactly sure about how to compare it. But the server is generally much faster in other situations.)</div><div class=""><br class=""></div><div class="">For example, for this script (<a href="http://paste.yt-project.org/show/5808/" class="">http://paste.yt-project.org/show/5808/</a>), on my local machine the output shows:</div><div class=""><br class=""></div><div class="">```</div><div class=""><div class="">yt : [INFO ] 2015-08-10 <b class="">14:48:15</b>,401 Making a fixed resolution buffer of (('gas', 'density')) 800 by 800</div><div class="">yt : [INFO ] 2015-08-10 <b class="">14:48:15</b>,751 Saving plot snapshot_200_Projection_z_density.png</div><div class="">yt : [INFO ] 2015-08-10 <b class="">14:48:16</b>,716 Saving plot snapshot_200_Projection_z_density.png</div></div><div class="">```</div><div class=""><br class=""></div><div class="">However, on the server the output shows:</div><div class="">```</div><div class=""><div class="">yt : [INFO ] 2015-08-10 <b class="">14:51:25</b>,551 Making a fixed resolution buffer of (('gas', 'density')) 800 by 800</div><div class="">yt : [INFO ] 2015-08-10 <b class="">14:51:25</b>,917 Saving plot snapshot_200_Projection_z_density.png</div><div class="">yt : [INFO ] 2015-08-10 <b class="">14:56:21</b>,922 Saving plot snapshot_200_Projection_z_density.png</div></div><div class="">```</div><div class=""><br class=""></div><div class="">That’s <b class="">296</b> times slower!!!</div><div class=""><br class=""></div><div class="">This is likely to be a very specific problem with the server. But I’d like to know if anyone else has encountered similar problems before so I can learn from your experience. For now, I have no idea what could have gone wrong.</div><div class=""><br class=""></div><div class="">BTW, I’m using TSCC (<a href="http://idi.ucsd.edu/computing/" class="">http://idi.ucsd.edu/computing/</a>) at UC San Diego, if you happen to know it.</div><div class=""><br class=""></div><div class="">Thanks,</div><div class="">Bili</div></body></html>
