Units
by Matthew Turk March 7, 2013

March 7, 2013

Hi all, Casey, Anna, Nathan, Britton and I have been working on units in 3.0, based on the stuff Casey's worked on before. Anna submitted a YTEP here: https://bitbucket.org/yt_analysis/ytep/pull-request/13/created-new-ytep-for… Comments on this would help shape the direction. We're currently knee-deep in the implementation details, but hopefully this will be in a workable state by the end of the workshop. -Matt

summing over phase plot and total quantity discrepancies
by Geoffrey So March 7, 2013

March 7, 2013

I'm trying to use add_phase_object to get a 2D distribution and summing over the y axis to see the total quantity in each x bins. I am using the old plot collection to do the phase distribution because it is parallelized, the binned2D is serial I believe. I'm checking the numbers by using TotalQuantity which sums all the cells in the simulation, and I should get the same number when I sum over the color axis of the phase plot (I'm assuming this is true, can someone also verify the logic?), … [View More]

Please don't delete your repositories
by Matthew Turk March 6, 2013

March 6, 2013

Hi everyone, This is an empassioned plea not to delete your repositories, especially if they have been the subject of pull requests -- successful or not. Once a repository has been deleted, all comments and code review are now gone. They can be reconstructed from email, but are otherwise lost. I've talked to BB support, and they suggested we open a feature request, but right now this is how things are. So please, once you have created a repo that forms the basis of one or more pull … [View More]

Good benchmark?
by Matthew Turk March 4, 2013

March 4, 2013

Hi all, I got an email asking for a benchmark of yt. I think this is very, very valuable to have going forward. I was wondering if anyone had any suggestions? I'm thinking that we probably want to test things like the halo finder, projections, and phase plots. Would a medium (1536^3) halo profiling run do that? Do we want to add on some global projections and phase plots as well? -Matt
