1. Review of last meeting and News
2. Glenna2 review and progress
Cloudification of the HARMONIE-AROME Weather Code in Azure
- As part of our MetCoOp collaboration Fredrik Robertsen from the Glenna2 team has worked on porting the HARMONIE NWP software to the MS Azure platform. We have ported the Harmonie version used in NSC:s (Linköping) benchmark suite
- The larger test case in the suite executed in 162 minutes on 128 cores which seems to be a reasonable result The Azure environment specifications are: 8 nodes, Azure h16r, 2x E5-2667 V3 3.2 Ghz, 112 GB memory and FDR InfiniBand (54.54 gbit/s max)
- researchers at Simula Research Laboratory in Norway have developed a virtual switch model https://www.simula.no/sites/default/files/publications/files/towards_the_infiniband_sr-iov_vswitch_architecture_-_cluster2015_camera-ready.pdf for InfiniBand Single Root I/O Virtualization (SR-IOV), but it does not appear to have gained widespread recognition yet. The model allows providers to quickly reallocate resources and provide live VM migration which is a critical capability to operating a production cloud system by allowing maintenance procedures without requiring user-visible downtime.
KubeNow - Easier Kubernetes Deployment
- KubeNow (https://github.com/kubenow/KubeNow) framework which is a cloud agnostic platform used for deploying a Kubernetes cluster using provisioning tools such as Terraform and Ansible on a cloud providers IaaS. It has been developed under the umbrella of the EU project PhenoMeNal (http://phenomenal-h2020.eu) and platform aims to simplify a Kubernetes deployment. KubeNow currently works on commercial clouds such as Amazon Web Services and Google Cloud Engine (GCE) as well as on private OpenStack installations.
- Kubernetes is an open source platform that automates Linux container operations.
- Groups of hosts can be clustered together running Linux containers, and Kubernetes helps with managing those clusters.
- These clusters can span hosts across public, private, or hybrid clouds.
- Kubernetes is an active topic at all the Nordic e-infrastructure providers
Dissemination
- Members from the Glenna2 team participated in writing a section about federated cloud access in the Nordics for a book on OpenStack in science presented at the SuperComputing 2017 (SC17) conference.
- The book is now officially out and is titled: The Crossroads of Cloud and HPC: OpenStack for Scientific Research: Exploring OpenStack cloud computing for scientific workloads and is available at Amazon:
- Nordforsk has a article about Glenna: Building a cloud for Nordic researchers
NeIC AHM 2018
For all the members of the Glenna2 team don’t forget we have the NeIC All Hands Meeting January 29 - February 01, 2018 at Skeikampen, Norway coming up.
