Subject: 2015-06-29 Interop. SC minutes

Minutes for 2015-06-29 Interop. SC call:

[08:05] Matt Rutkowski (IBM): Attendees: Matt, Derek, Sahdev, Chris, Karsten, Peter
[08:10] anonymous: tried also to join the conference services room 6789269 but system is saying not yet been started ? is that only an issue on my side
[08:10] Matt Rutkowski (IBM): who is anonymous?
[08:10] anonymous morphed into Peter Gibbels
[08:10] Matt Rutkowski (IBM): can u set your name and company please in settings
[08:10] Matt Rutkowski (IBM): ahh
[08:10] Peter Gibbels morphed into Peter Gibbels (HP)
[08:10] Matt Rutkowski (IBM): Hi Peter
[08:10] Peter Gibbels (HP): Hi Matt
[08:11] Matt Rutkowski (IBM): we are not screen sharing at the moment
[08:11] Peter Gibbels (HP): o.k thanks, then I am o.k :-) just wondered
[08:11] Matt Rutkowski (IBM): I can start if we need to look at some files, but we have not had to recently
[08:14] Matt Rutkowski (IBM): Issue in create scripts identified
[08:14] Matt Rutkowski (IBM): with apt-get
[08:15] Matt Rutkowski (IBM): serialization issues because multiple create scripts running and apt-get not parallel processing aware
[08:15] Matt Rutkowski (IBM): Derek: This is not a limitation of Linux, code does not hurt, but needs to acknowledge the real problem and impls. must serialize appropriately
[08:16] Matt Rutkowski (IBM): Derek: on same Compute (node) you should not parallelize scripts (too much assumed is dangerous) should serialize typically
[08:17] Matt Rutkowski (IBM): Sahdev: collectd and rsyslog are running in parallel in same node. Others run on their own nodes.
[08:18] Matt Rutkowski (IBM): Derek: Having the loop is never a good idea. Cant rely on scripts to consider order and parallel processing
[08:18] Matt Rutkowski (IBM): Derek: All TOSCA orchestrators should handle serialization and ordering
[08:20] Matt Rutkowski (IBM): Derek: recommend serialization in the same node. Transient states possible. Parallelism is a goal, but safer to serialize
[08:21] Matt Rutkowski (IBM): Matt: please annotate scripts as a Heat-Translator workaround (not able to yet serialize) and can be removed by other TOSCA impls
[08:21] Matt Rutkowski (IBM): Derek: Why do we have python and bash scripts in different folders?
[08:22] Matt Rutkowski (IBM): Matt: TOSCA needs to show declarative and not have these kinds of workaround code or no value over imperative
[08:22] Matt Rutkowski (IBM): Sahdev: just a logical separation
[08:22] Matt Rutkowski (IBM): Derek: when we extract we move scripts to different places, would need to adjust to this paradigm
[08:23] Matt Rutkowski (IBM): Derek: so CSAR structure is just the designers preference
[08:23] Matt Rutkowski (IBM): Derek: Do we have MIME info?
[08:25] Matt Rutkowski (IBM): Matt: we SHOULD support filling in MIME type info, it is in spec. for both BASH and Python
[08:25] Matt Rutkowski (IBM): Matt: SHOULD be in template def. for artifacts, if not we SHOULD lookup based upon file extension
[08:26] Matt Rutkowski (IBM): Derek: not big deal, his developers can adapt ifnot there
[08:30] Matt Rutkowski (IBM): Matt: Simple profile should be able to auto. identify .py and .sh extensions and assign a MIME type based upon norm. types defined in spec.
[08:32] Matt Rutkowski (IBM): Matt: Sahdev continue to work with Chris on making sure our 2 demos have variety
[08:39] Matt Rutkowski (IBM): Matt: Sahdev will upload a video to the TC by EOD, tuesday July 7th; Final by July 9th for TC review
[08:39] Matt Rutkowski (IBM): Matt: this helps Fujitus and others using same HEat-Translator codebase see what we intent to show
[08:46] Matt Rutkowski (IBM): Derek: will we splice videos?
[08:46] Matt Rutkowski (IBM): Matt: not a goal, more jukebox approach
[08:46] Matt Rutkowski (IBM): Karsten: Eurocloud we rotated videos, IBM, HP< Huawei etc.
[08:46] Matt Rutkowski (IBM): Derek: we may want to focus on tooling
[08:47] Matt Rutkowski (IBM): Peter: Presenter (whoever was up at the time) could choose videos they were most comfortable showing
[08:51] Matt Rutkowski (IBM): Matt: IBM is shooting for 3 mins max.
[08:52] Matt Rutkowski (IBM): Matt: MPEG4 that works on MS Player and Quicktime player
[08:54] Matt Rutkowski (IBM): Matt: upload to TC working directory, in past we had new directory but no one used so just use the one we use at TC for everything
[08:54] Matt Rutkowski (IBM): Derek: In future we should work to show diff script types for different platforms (e.g. RHEL vs Ubuntu)
[08:59] Matt Rutkowski (IBM): Matt: we are adjourned
