Hi Britton, <br>
<br>
I have subscribed to both yt-users and yt-dev. It may possible my requests are pending. As far as dataset is concern, Geoffrey can give you better explanation about it.
<br>
<br>
Dataset contains 0-64 regions. I tried to run ParallelHOP with all regions but because of memory issue, I could not able to complete all in once. Then I ran it with only 0-3 regions to debug code "parallel_hop_interface.py".
<br>
<br>
Please also find attached script. Let me know, if you have more questions. <br>
<br>
<br>
Thanks<br>
Pragnesh<br>

<div>Hi again Pragnesh,<br>
<br>
I mistakenly asked you to post this to the enzo-users mailing when I meant to say that you should post this to the yt-users mailing list. Sorry about that, not enough coffee this morning.<br>
<br>

Hi Pragnesh,<br>
<br>
You need to provide us with some more information. What do you mean when you say you ran for 0-3 regions? What kind of dataset are you trying to analyze? How big is it? Can you also please post the script you are using for this?<br>
<br>
Finally, could you please sign up for the enzo-users mailing list and post this there? You've posted this to the development list, which isn't the best forum for this question. Also, if you're not on the list you won't receive any of the responses to your
post.<br>
<br>

Hi Stephen, <br>
<br>
I found memory leak issue, when I ran Parallel_HOP code. It may not be in python itself but may be in packages(e.g. kdtree etc..), which we call from"parallel_hop_interface.py". Please find attach file, in which you see memory keep increase in every region
(I ran program with 32 processes for 0-3 regions.)<br>
<br>
I like to get your comments/suggestions to solve this issue. <br>
<br>
I am trying to find more about it using Valgrind. I will let you know. <br>
<br>
Thanks<br>
Pragnesh<br>
