Ok, I am not 100% sure what is going on, I've only tried this a few times with dm_only, but I have noticed not too many other people are around, so I will tell you what I know. There are some quirky things with dm_only, for instance: if you start with from yt.mods import * pf = EnzoStaticOutput("datasetname",data_style="enzo_packed_3d") (or pf = load(...)) the behavior of creating plot collections, reading field lists is different than if you use from yt.lagos import * pf = EnzoStaticOutput("datasetname",data_style="enzo_packed_3d") In the first case, if you type print pf.h.field_list it fails in the second case, it works. Unclear why. You can project quantities, or take slices, but not for all the particle quantities as they are (as near as I can tell). Some of the derived quantites (e.g. particle_density_pyx) can be projected without a problem, once you import raven. Though I am not the expert on the particle quantities, I seem to remember that you can only take slices/ projections with grid quantities. Anyway, I would start with loading up the data by importing lagos first, loading the dataset, then check your field list and derived field list for what you want to make slices of. There is some more documentation on the enzotools site on how to manage particle data etc. Hopefully someone else can help with the real answers here at some point. Sorry I couldn't help more.

Re: [yt-users] [Enzo-users-l] Compiling Enzo on TACC Ranger

by kcai＠pa.uky.edu

Hi Matt, Last night I was browsing the archives of the yt-users list, and came across this thread of emails: [yt-users] corrupt enzo restart file? Matthew Turk matthewturk at gmail.com Thu Nov 12 09:30:36 PST 2009 Hi Stephen, A problem with the way yt opens up dark matter only simulations is that the data_style has to be specified. This would be, for running on trunk, done with the parameter: data_style="enzo_packed_3d" to the StaticOutput initialization. Britton Smith has done some work recently on improving this, so he might be able to chime in with more info. -Matt On Thu, Nov 12, 2009 at 9:27 AM, Stephen Skory <stephenskory at yahoo.com> wrote: > Hi all, > > I am getting this error <http://paste.enzotools.org/show/257/> when > I attempt to instantiate the grid hierarchy. ......

r_min in HaloProfiler

by Agarwal, Shankar

Hi, While running HaloProfiler, I am seeing this... P001 yt.lagos ERROR 2009-12-08 15:53:22,403 Skipping halo with r_max / r_min = 1.885682. I looked at yt/extensions/HaloProfiler.py... r_min = 2 * self.pf.h.get_smallest_dx() * self.pf['mpc'] if (halo['r_max'] / r_min < PROFILE_RADIUS_THRESHOLD): mylog.error("Skipping halo with r_max / r_min = %f." % (halo['r_max']/r_min)) r_max would be the distance to the furthest particle in the halo as found by HaloFinder. But what is r_min ? And what is the basis for skipping this halo ? shankar

HaloFinder- parallel is slower?

by Agarwal, Shankar

Hi, I ran yt's HaloFinder routine on 1 processor, and then on 8 processors. Both give identical output : 40,000 halos starting from 512^3 particles. 1 processor : took 1 hour 45 minutes. 8 processors : took 2 hours. My script is hop_yt.py.... from yt.mods import * fn = "RedshiftOutput0002" pf = load(fn) halos = HaloFinder(pf,40,padding=0.02) halos.write_out("HopAnalysis.out") commands I used.... mpirun -np 1 python hop_yt.py --parallel mpirun -np 8 python hop_yt.py --parallel Any idea why 8 cpus would take longer ? shankar

running halo_profiler.py using mpi4py

by Agarwal, Shankar

Hi, I have about 40,000 halos (using Hop_Finder). And I want to run Halo_profiler on it. Since the number of halos is so large, I would like to use... mpirun -np <cpus> halo_profiler.py --parallel Steele-purdue has 8cpus per node. The 8 cpus have shared memory. But the nodes do not share memory. I want to know would I be better off using just 8 cpus (on 1 node) or should I use more nodes, considering I have 40,000 halos. regards shankar

Hop vs HaloProfiler

Hi, I am a little confused as to how to use hop_circles. I tried this but it fails... from yt.mods import * fn = "RedshiftOutput0002" pf = load(fn) halos = HaloFinder(pf) halos.modify["hop_circles"](self, hop_output, max_number=None, annotate=False, min_size=20, max_size=10000000, font_size=8, print_halo_size=False, print_halo_mass=False, width=None) halos.write_out("HopAnalysis.out") Also, I tried HaloProfiler using http://yt.enzotools.org/doc/cookbook/recipes.html#cookbook-run-halo-profiler. It generated the radial_profiles/ directory with Halo_xxxx_profile.dat files.

limits of the colorbar

by Agarwal, Shankar

Hi, I tried to set the limits of the colorbar using set_zlim as below... fn = "RedshiftOutput0002" pf = load(fn) pc = PlotCollection(pf,center=[0.5,0.5,0.5]) p = pc.add_slice("Density", 0) p.set_zlim(1e-31, 1e-30) pc.save() But I keep getting a plot with colorbar ranging between (1e-31,1e-28). I can't see what I am missing. shankar
