Fwd: Blue Waters Advanced User Workshop and yt development workshop
by Matthew Turk Sept. 12, 2014

Sept. 12, 2014

Hi everyone, As noted below, there's going to be a development workshop for yt at NCSA at University of Illinois Urbana-Champaign, on October 16 and 17. This is going to be a dev workshop, but *everyone* is invited (whether you use Blue Waters or not!). There isn't yet a set schedule, but I hope we can spend time on solidifying support for newer frontends, attaching to running simulations, and hopefully even converting the n-body codes to forest-of-octree from the current implementation. I'm … [View More]

How to issue multiple PR's on BitBucket?
by Chris Malone Sept. 11, 2014

Sept. 11, 2014

Hey devs, I apologize in advance for my naivety... I asked this in IRC, and Kacper was kind enough to provide some insight, but alas I was still having problems getting this to work. I know it involves bookmarks and heads, but I'm still not as familiar with mercurial as I am with git, so this all confuses my gitsense. Also, I know there are others who have this issue - perhaps this should be on the docs page somewhere... Let's say I have my fork of yt wherein I already have a pending PR on … [View More]

Issue #896: Inconsistent total mass in Gadget snapshots spread over multiple files (yt_analysis/yt)
by afitts Sept. 10, 2014

Sept. 10, 2014

New issue 896: Inconsistent total mass in Gadget snapshots spread over multiple files https://bitbucket.org/yt_analysis/yt/issue/896/inconsistent-total-mass-in-g… afitts: There is a difference in what the total_mass() reports when using a snapshot from a single file and a snapshot from multiple files. What's even stranger is that if you query total_quantity("PartType*_mass") both the single and multiple file snapshots match up. The corresponding snapshots and script can be found here: https://www.dropbox.com/s/2t5pzgwgc7fug9n/massbug.tar.gz?dl=0

Issue #895: Can't load mass of stars from Gadget snapshots written to multiple files (yt_analysis/yt)
by afitts Sept. 10, 2014

Sept. 10, 2014

New issue 895: Can't load mass of stars from Gadget snapshots written to multiple files https://bitbucket.org/yt_analysis/yt/issue/895/cant-load-mass-of-stars-from… afitts: I have this recurring problem when using snapshots written to multiple files with Gadget. I'm interested in following the total stellar mass at each time step. However when using multiple files i get the error: http://paste.yt-project.org/show/5107/ when trying to reference particular files. I redid my simulation writing … [View More]

Hi everyone, Members, if you are interested in taking on some leadership within yt, please consider signing yourself to be a representative for one for the five subcomponents: infrastructure, plotting, testing, documentation, and analysis modules. If you have experience with one of these areas or are interested in becoming more involved in planning and/or development, consider yourself right for the position. An area should ideally be represented by at least a two or three people. All that … [View More]

Issue #894: Test suite does not detect load function breakage (yt_analysis/yt)
by Andrew Myers Sept. 8, 2014

Sept. 8, 2014

New issue 894: Test suite does not detect load function breakage https://bitbucket.org/yt_analysis/yt/issue/894/test-suite-does-not-detect-l… Andrew Myers: This issue came up regarding PR 1190. Currently, if one breaks the code in such a way that the load function fails for certain datasets, the test suite will skip those datasets instead of reporting a failure. IME, breaking the _is_valid methods is really easy to do when doing frontend work, and it be nice if the answer tests reported a … [View More]

Issue #893: Feature request: specify xyz or zyx order in load_octree (yt_analysis/yt)
by astrofrog Sept. 7, 2014

Sept. 7, 2014

New issue 893: Feature request: specify xyz or zyx order in load_octree https://bitbucket.org/yt_analysis/yt/issue/893/feature-request-specify-xyz-… astrofrog: The load_octree currently makes assumptions about how to map the 1-d array of quantities into three dimensions. I think it varies fastest along z, then along y, then along x. It would be nice to be able to specify this order using an argument that could be set to either e.g. ``xyz`` or ``zyx``.

Nomination: Kenza Arraki
by Matthew Turk Sept. 3, 2014

Sept. 3, 2014

Hi all, I'd like to nominate Kenza Arraki for membership. Kenza has acted as the representative for the NMSU-ART code, and has spent a considerably amount of time and effort working on making sure it's correctly set up, and usable for the folks using it. I think she would be an excellent liaison for NMSU-ART, and a great addition to the membership ranks. -Matt
