Technical coordination group members and invited persons

4 October 2016, 14:10 - 15:15

Present: Balazs, Jon, David, Aleksandr, Maiken, Oxana
Apologies: Anders, Mattias


= ARC Camp

Settled to 28 November - 2 December, in Monor (near Budapest, Hungary). Accommodation and catering will be covered from the NordForsk project. Will start with brainstorming, then when everybody gets tired the normal day-to-day business will be addressed.


= News

Balazs followed remotely the digital infrastructures meeting in Cracow, there was an interesting workshop on future infrastructures, all based on high-level data services and such, no place for things like CE.

David and Oxana were at the ATLAS software week, much discussion on how to use HPC resources, especially in the US, there's an idea to implement a Harvester of cycles of all kinds, resembling aCT: asynchronous data staging, feedback loop from sites. Americans also want to get rid of SRM at small sites. Lots of hype about ObjectStore, but not rreally used for large datasets.

NeIC is hiring a storage expert.


= Release

There's a new commit from Florido which might go in after testing today. Aleksandr has worked lots on openssl, but presumably not ready yet. ARC will work with OpenSSL down to 1.0.2 - 1.0.0 and 1.0.1 are not supported. Anders argues that OpenSSL 1.0.1 must be supported because it is in EL6, thus we can not merge the OpenSSL into the release yet.

 

= Bugs

Accumulation of NEW unattended bugs needs to be addressed in ARC Camp.

* 3601: appears to be fixed in r30331
* 3593: also an openssl 1.1 question
* 3603: is probably a simple fix, but needs a proper expert to fix it
* 3596: another scalability bug, might be rectified by throttling cancellations
