Hello, I'm just getting started again on using Docker multi-arch for building AArch64 NEST binaries, following this instruction: https://engineering.docker.com/2019/04/multi-arch-images/ Has anyone had a chance to create a handy Dockerfile for building NEST? Could you share it via this mailing list? Thanks, Itaru.

Exception handling in NEST

by Itaru Kitayama

Hi, Am I able to safely comment out all those exception handling codes provided they're provided for the defensive purposes? I ask because I am trying to insert offloading directives into the NEST code base wherever I can. Thanks, Itaru.

Open NEST Developer Video Conference Monday 29 April 2019 11.30 CET (UTC+2)

by Dennis Terhorst

Dear NEST Developers! I would like to invite you to our next bi-weekly Open NEST Developer Video Conference today Monday 29 April, 11.30-12.30 CET (UTC+2). See below for information about how to log into the meeting. The agenda for this meeting is also available online https://github.com/nest/nest-simulator/wiki/2019-04-29-Open-NEST-Developer-… 1. Welcome 2. Review of NEST User Mailing List <https://www.nest-simulator.org/mailinglist/postorius/lists/users.nest-simul…> 3. Review of open Github Pull Request <https://github.com/nest/nest-simulator/pulls> 4. Review of open Github Issues <https://github.com/nest/nest-simulator/issues> See you soon! best, Dennis Terhorst ------------------ Log-in information ------------------ We use a virtual conference room provided by DFN (Deutsches Forschungsnetz). You can use the web client to connect. We however encourage everyone to use a headset for better audio quality or even a proper video conferencing system (see below) or software when available. *Web client* * Visit https://conf.dfn.de/webapp * Enter your name and allow your browser to use camera and microphone * Click green video-call button to open the call panel * In the "Search to call" box at the top right enter *97938800* and connect * The conference does not need a PIN to join, just click *join* and you're in. In case you see a dfnconf logo and the phrase "Auf den Meetingveranstalter warten", just be patient, the meeting host needs to join first (a voice will tell you). *VC system/software* How to log in with a video conferencing system, depends on you VC system or software. - Using the H.323 protocol (eg Polycom): vc.dfn.net##97938800 or 194.95.240.2##97938800 - Using the SIP protocol:97938800@vc.dfn.de - By telephone: +49-30-200-97938800 For those who do not have a video conference system or suitable software, Polycom provides a pretty good free app for iOS and Android, so you can join from your tablet (Polycom RealPresence Mobile, available from AppStore/PlayStore). Note that firewalls may interfere with videoconferencing in various and sometimes confusing ways.

Network build phase questions

by Itaru Kitayama

Hi all, I'm wondering whether the vtable lookup connect function and random number generation costs during the network build phase are fully investigated and understood in the past. I ask because I've observed the phase is, while it is a simulation preparation, takes up to 60% of wall clock time of the entire simulation. Thanks, Itaru.

NEST Conference 2019 --- Abstract submission extended to 23 April

by Hans Ekkehard Plesser

Dear colleagues! We are looking forward to welcoming you to NMBU's beautiful campus south of Oslo for the NEST Conference 2019 on 24/25 June 2019 (Monday/Tuesday) To give you a chance to include your latest results in your NEST Conference 2019 Abstract, we have EXTENDED the ABSTRACT SUBMISSION DEADLINE to TUESDAY 23 April Please submit your one-page abstract by email to conference(a)nest-initiative.org using the template available from http://www.nest-initiative.org/conference As we experienced problems with our email system in recent weeks. If you have submitted an abstract, but not received a confirmation of receipt, please submit your abstract once more by mail to conference(a)nest-initiative.org. We apologise for the inconvenience. The NEST Conference provides an opportunity for the NEST Community to meet, exchange success stories, swap advice, learn about current developments in and around NEST spiking network simulation and its application. We would like you to share your experiences made and results obtained with NEST during the conference. You can do so either by a short oral presentation (10–15 minutes), on a poster, through a demo, or by organizing group work. Important dates • 23 April 2019 — Deadline for abstract submissions • 01 May 2019 — Notification of acceptance • 15 May 2019 — Deadline for registration For details, abstract submission and registration, please see http://www.nest-initiative.org/conference You are also welcome to contact us at conference(a)nest-initiative.org.
