Hi all, I was trying out pobj_demo.py from the workshop to see if I can parallelize my halo analysis script, but I ran into the problem where I see:<div><br></div><div>&gt;mpirun -n 2 python pobj_demo.py --parallel</div><div>
<br></div><div>gives a warning at the end</div><div><br></div><div>yt : [WARNING  ] 2012-03-16 16:25:05,445 parallel_objects() is being used when parallel_capable is false. The loop is not being run in parallel. This may not be what was expected.<br>
</div><div><br></div><div>I&#39;ve done a</div><div>yt instinfo -u and got the latest tip:</div><div><br></div><div><div>052fac826701 (yt) tip</div></div><div><br></div><div>but the problem persists.  I&#39;ve tried printing inside the parallel loops</div>
<div><br></div><div><div>for sto, sp in parallel_objects(spheres, num_procs, storage = my_storage):</div><div>    print ytcfg.getint(&quot;yt&quot;, &quot;__global_parallel_rank&quot;)</div><div>    sto.result = sp.quantities[&#39;TotalQuantity&#39;](&#39;CellMass&#39;)</div>
<div>    sto.result_id = &#39;%4e %4e %4e&#39; % (sp.center[0], sp.center[1],sp.center[2])</div></div><div><br></div><div>and I always get &quot;0&quot;, but 20 of them, so I&#39;m guessing that confirms the loop isn&#39;t running in parallel, and just runs the 10 spheres serially on 2 processors, so I get double the results.</div>
<div><br></div><div>Am I doing something wrong or missed something?</div><div><br></div><div>From</div><div>G.S.</div><div><br></div><div><br></div>
