Hey everyone, The following error pertains to the yt branch of the hg repo. I'm getting a particle io error when using the various yt halo finders in parallel. It doesn't appear to have anything to do with the halo finders, but I don't know what else uses ParticleIO.py. This only happens when running in parallel.

Hi Britton, ParticleIO is still kind of new, I guess! I think there's something wrong with the dependency calculator in this case -- something about the hackery around particle_mass and "particle mass". There are two ways forward for this that I think we need to think about -- global field name translations, and fixing the field dependencies. If you fill out a ticket for this problem, I'll examine it this coming week... -Matt On Fri, Nov 27, 2009 at 2:43 PM, Britton Smith <brittonsmith@gmail.com> wrote:
