[Users] meeting minutes for 2019-06-13

[Haas, Roland]

Present: Helvi, Roland, Peter, Yosef

ET tutorial server
* cannot currently create account requests via web-form: fixed as of
  beginning of week, was broken March till June
* compiling produces many server down / server up emails: still happens
  due to latency of frontend responding to http requests, could either
  ask to move VM to different node or to split system into "login" VM
  and "worker" VMs for users
* Roland to ask admins to move to a different hardware node

Provide compiled version of the ET
* https://bitbucket.org/einsteintoolkit/tickets/issues/2260/provide-compiled-et-code-on-tutorial
* useful for people that are less experienced in numerical work, which
  may also be the same group of people that are likely to have problems
  setting up docker
* Helvi may have time to try this out on her Ubuntu system, serving as
  a test-case since she has never used docker before

Memory issues:
* https://bitbucket.org/einsteintoolkit/tickets/issues/2194/memory-increase-during-regridding
* initial idea was that this could be communication buffers that were
  never shrunk
* patch that frees this memory was provided but does not seem to help
  in all cases
* two more cases that fail, small one by Miguel, large one by Gabriele
* memory usage in failing case by Miguel is very uneven, possibly due
  to communication buffers

ET US workshop at RIT
* broadcast will likely be done via bluejeans
* working on having camera and mike for remote participants to see the
  screen and the audience
* also for lunch discussion
* link will be send to mailing list and be available on workshop page
https://ccrg.rit.edu/content/events/2019-06-17/north-american-einstein-toolkit-workshop-2019/

  discussion
