Hi Eric,

Matt's suggestion would be helpful.  If you were running the code successfully at any time recently, it should be simple to track down the revision where it breaks.
Does the halo filter list actually get written out?  I assume this is only hanging when running in parallel, but correct me if I'm wrong on that.  Looking at the light cone and halo profiler code, the function where the hang occurs is called from functions that have various parallel decorators around them, which are probably adding a number of barriers.

Eric, if you can run "hg bisect" (see the hg book online) to identify the revision this started at, that would be very handy. I would start b going back only a dozen or so. Does this problem occur on smaller datasets on, say your laptop or desktop?

I am getting a hang when I run the lightcone tools on ranger, and no debug info is coming out at the hang. this is in the hg version (current) of yt.

The routines I'm running is called test_vel_mask.py, which is creating a lightcone with a halo map that includes the bulk line of sight halo velocity.  It includes  a slight modification of HaloMask.py to include velocities.  However, I removed my changes, and ran again with the same hang. The routine below is copied nearly directly from the yt docs, with minor changes.

Routine is attached as test_wo_vel.py

<test_wo_vel.py>



Hang occurs with text line:
yt.lagos   INFO       2010-04-05 12:06:15,657 Writing filtered halo list to /scratch/00688/tg458377/box_size_study/50Mpc_1024/run_12_cl_5D/RD0004/virial_filter.out.

traceback is attached as test_vel_traceback.out

Thanks for any help...

cheers
