@pieper Here’s a library for managing cloud resources

Apache Libcloud is a standard Python library that abstracts away differences...

Notes and Action Items

• Discussed issue with having more than one CLI running parallel

  • Multiple CLIs can be scheduled for execution but here is only one processing thread
  • Testing code in KitwareMedical/SlicerParallelTest demonstrate the current issues
  • Topic jcfr/Slicer@support-running-cli-in-parallel updates vtkSlicerApplicationLogic to create multiple processing thread. It is a work-in-progress and requires more testing as there are issues with properly reading stream of processes and updating status of relevant command line module nodes.

• Integrated PR5528 and PR-5527

• libcloud provides an abstraction to interface with google cloud, aws, digital ocean, … see https://libcloud.apache.org/ . @pll_llq as some experience using it.

• versioning

  • add updated versioning scheme document to readthedocs based on Propsal 3

• new stable release (PR-5525)

  • Do not create any more snapshot releases including YYYYMMDD. This caused issues with version comparison (see here)
  • Create a new release called 4.14 and then update master to be 4.15

• Reviewed Pluggable Markups PR-5349 from @RafaelPalomar

  • Avoid exporting module libraries.
  • Revisit how function qSlicerMarkupsModuleWidget::setMarkup() is exposed in the the module API.

• slicer.org: new design

  • Address remaining issues (e.g consolidate sitemap and top-toolbar, fix style of “Extensions” and “Community” sections, …)
  • Get feedback from @faiza.ahmed

• “parallel coordinates demo” from @pieper

  Movie and the repo from the earlier iteration of this concept that uses the same js/python infrastructure, but this time to display statistics about different MRI contrasts within segments (plot lines are colored to match segments) and to display segmentation based on selection from within the plot (current brushed region shows blue as segmentation overlay on volumes).
