[yt-users] YT: Rockstar Halo Finder

[Jacob Kneibel]

Hello,

I've been trying to run the Rockstar Halo finder on a 1536^3 unigrid  
Enzo simulation and have been running into a few issues. I am using  
the Blue waters machine and when I run the finder with multiple  
readers, the process is killed by the OOM killer, and when I run it  
with one reader there is a Network IO error.

My yt version is 3.2-dev, changeset= 8ad62b624390

Here is the python script I am running:
http://paste.yt-project.org/show/5631/

and here is the job script I'm submitting to blue waters:
http://paste.yt-project.org/show/5632/

I've tried different node and ppn settings, with no luck.

Does anyone have an idea on how to get rockstar to run on the blue  
waters system with this large simulation? Or is there a recommended  
number of readers based on the number of nodes I set?

Thank you for any help you can give,

Jacob Kneibel
