[Yt-dev] quick question on particle IO

Hi YT devs, I was asked by the sys admin at NICS about a part of YT that I'm not very familiar with: "Is the particle IO in YT that calls h5py spawned by multiple processors or is it doing it serially?" We're trying to solve a memory issue we're seeing in the parallelHF, and Stephen has been making modifications that I'm currently trying out, but we wanted to see if we can identify the source of the problem. I told the admin that parallel projection works with each processor reading in only a portion of the field variables, but I couldn't be sure about the particle data, so I wanted to verify with people on the dev list.
