parallelHOP in yt-3
by Josh Moloney April 5, 2016

April 5, 2016

I've recently been trying to get parallelHOP integrated into the current version of yt-3. (I need halo finding with star particles which I think rules out Rockstar, and I eventually need to work with grids up to 1536^3 which would be problematic with regular HOP.) I currently have it working properly for single core runs, and it produces output that matches the yt-2.x version. It also runs to completion with mpi, and produces mostly sensible output. However, when run on multiple cores it has … [View More]

Issue #1205: default disparity in StereoPerspective lens doesn't show much difference between left and right (yt_analysis/yt)
by Michael Zingale April 3, 2016

April 3, 2016

New issue 1205: default disparity in StereoPerspective lens doesn't show much difference between left and right https://bitbucket.org/yt_analysis/yt/issues/1205/default-disparity-in-stere… Michael Zingale: Depending on what you are rendering, when you do a volume rendering with the lens="stereo-perspective", the left and right images do not look at all different. To fix this, you need to change the disparity parameter, like: ``` sc.camera.lens.disparity = cam.width[0]/10.0 … [View More]

New install script
by Nathan Goldbaum April 1, 2016

April 1, 2016

Hi all, I'm almost finished updating the install script so that by default it creates a conda-based installation, but can also optionally do a from-source bootstrapped installation. https://bitbucket.org/yt_analysis/yt/pull-requests/2009 Before the pull request can be merged, it needs testing on a variety of platforms as well as some sort of test script we can run as part of the test suite. If any of you have some time and interest in helping me out, I'd appreciate it if you could try. You … [View More]

Sequence of buff_size
by Yi-Hao Chen April 1, 2016

April 1, 2016

Hi all, Running this test script http://paste.yt-project.org/show/6379/ will result in this image https://slack-files.com/T042F73QM-F0X0YJE3V-4a579d9431 Apparently, the sequence of buff_size is switched so that set_buff_size((8,4)) gives a 4 by 8 image. I have traced down the codes and found the following lines are the cause of the problem. https://bitbucket.org/yt_analysis/yt/src/d18f33211199f71e2fac4d927307b015d5… https://bitbucket.org/yt_analysis/yt/src/… [View More]

Contribution graph
by Matthew Turk April 1, 2016

April 1, 2016

Hi folks, I know we don't have a contribution graph for yt on bitbucket the way github does, but this piece still really hit home for me. Thanks to Nathan for posting it in Slack; I thought it deserved amplification here. http://erik.io/blog/2016/04/01/how-github-contribution-graph-is-harmful/ -Matt

[ANN] xs 1.0: The next generation of yt
by Matthew Turk April 1, 2016

April 1, 2016

Dear everyone, I am proud to announce the release of xs 1.0: the next generation of yt. xs is a new package, designed from the ground up to take advantage of emerging architectures and to address challenges presented by the next generation of computing hardware. In keeping with this vision, xs facilitates the deployment of complex analysis pipelines as defined at compile time, rather than run time as is common in most yt usage. For more information, including compilation instructions, … [View More]
