Hackathon projects/tasks

Below a couple of potentially interesting open issues are listed that can be tackled during the hacking sessions:

Get started with EasyBuild

Try and get EasyBuild working on your system(s) of interest:

  • install EasyBuild
  • run the framework unit tests:
python -m test.framework.suite

Review an open pull request, provide feedback

We maintain a "two pairs of eyes" policy for contributions, i.e. someone else than the other has to review a contribution for it can be merged in (see also Review process).

Pick any open pull request you care about, review it, and provide feedback:

easybuild-framework - easybuild-easyblocks - easybuild-easyconfigs

Implementing a custom module naming scheme that matches your site poilcy

Since version 1.8.0, EasyBuild has support for using custom module naming schemes. If your site maintains a strict policy w.r.t. module naming, try and implement it with the support EasyBuild currently has, and supply feedback on what's missing or what can be improved.

Adding support for building and installing additional software packages

Implementing requested features

Try and implement a feature that was requested, for example:

  • a better 'quick demo for the impatient' (framework/#442) ** something that's actually quick, and can be used for tutorials, workshops, introductions ** compiler toolchain based on TinyCC, with a default (slow) netlib BLAS and LAPACK (without MPI support)?
  • fail early when sanity check paths/commands are not what they should be (framework/#703)
  • define toolchain environment variables in toolchain modules (framework/#604)
  • make sure that all easyconfig parameters are available for alternative module naming schemes (framework#687)
  • trip over unknown configure options (easyblocks/#157)
  • cmake: add support for "out-of-source" build (easyblocks/#215)

Browse through the lists of open issues, and pick a feature request you care about:

easybuild-framework - easybuild-easyblocks - easybuild-easyconfigs

Remote participation

Together with the local organizers, we would like to make it possible for people who are not attending the hackathon physically to participate remotely.

  • the presentations on EasyBuild and UNITE will be recorded, and we will do what we can to make these recordings available as quickly as possible.
  • we will also try to stream the talks as they happen, so people can tune in remotely (if you have any suggestions on tools for this, let us know).
  • the slides of the talks will be available up front on the EasyBuild wiki.
  • we plan to schedule conference calls (Skype and/or Google Hangouts) with remote attendees to answer any questions they may have on the work they're doing with EasyBuild (see schedule below)
  • the #easybuild IRC channel is the prime way for communicating with (remote) attendees and other EasyBuild enthusiasts outside of the hackathon conference calls

The idea is that remote participants can try and tackle open issues on EasyBuild (doesn't matter what, any issue you care about), just like the hackathon attendees, and get help when/if they need it.

Preparation

To try and make these efforts work, it's important to plan ahead and get an idea of who would like to participate remotely.

The main things we would like to get a view on is:

  • the number of remote participants
  • at which times they are planning to participate

We would like to schedule the conference calls such that the time at which they take place works well on both ends of the wire, i.e., taking into account time zone differences.

Register your remote participation

If you would like to remotely participate in the 4th EasyBuild hackathon, please let us know before Friday Oct 18th 2013 1pm (CET) by filling in the doodle at http://doodle.com/625h6t2teegqp326.

Please clearly indicate you'll be participating remote by adding a (remote) tag next to your name. Once we have a clear view on the remote participants, we will work out the details together with them.

Conference calls

Conference calls will be done using Google Hangouts (via Google Plus), since that's the least restrictive (access to Google Plus is free, group conference calls on Skype now require the non-free Skype Premium option).

Schedule

Cypriot time potential remote attendees notes
8.15am Bill & Adam (10.15pm) before hackathon starts (possible?)
1.30pm Ward & Petar (12.30pm) during hackathon lunch break
6pm Ward & Petar (5pm), Bill & Adam (8am) after hackathon
11pm (?) Ward & Petar (10pm), Bill & Adam (1pm) after local dinner (exact time uncertain)

Notes

Something went wrong with that request. Please try again.
