Summit: How IBM and Oak Ridge laboratory are changing supercomputing

The team designing Oak Ridge National Laboratory's new Summit supercomputer correctly predicted the rise of data-centric computing – but its builders couldn't forecast how bad weather would disrupt the delivery of key components.Nevertheless, almost four years after IBM won the contract to build it, Summit is up and running on schedule. Jack Wells, Director of Science for Oak Ridge Leadership Computing Facility (OLCF), expects the 200-petaflop machine to be fully operational by early next year.[ Now see who's developing quantum computers.] "It's the world's most powerful and largest supercomputer for science," he said.To read this article in full, please click here

Weekly 393 – Infrastructure Monitoring with Juniper AppFormix (Sponsored)

Juniper Appformix is a telemetry platform thats multi-vendor, cross layer, built-in machine learning and
with fancy visualisation. Its designed simplify operations and closed-loop automation.  In the era of multi-cloud, we need tools that run on-prem or in cloud and support OpenStack, K8s, VMware, Azure, Google, Amazon networks with integration into virtual machines, containers, overlay networks and physical devices.

The ability to draw data from a wide range of sources creates data flood that can overwhelm you. Appformix has machine learning and a range of automation functions to simplify and organise this diverse data flood. The increasing complexity of networks as the the edge of the network expands in multiple dimensions – on and off premises, virtual edge, overlay networks as well the physical devices must all operate in cahoots.

Appformix is automating this operational load so you aren’t getting calls at 2am. Thats a very fine thing.

Sumeet Singh, VP/GM for Juniper AppFormix, kicks off the discussion with a quick intro to Appformix, we cover the key features and the approach of the product before we move into use cases and what customers are using today. Surprisingly, this includes WAN operations in addition to DC/Cloud.

IDG Contributor Network: Living on the edge: 5 reasons why edge services are critical to your resiliency strategy

When it comes to computing, living on the edge is currently all the rage. Why? Edge computing is a way to decentralize computing power and move processing closer to the end points where users and devices access the internet and data is generated. This allows for better control of the user experience and for data to be processed faster at the edge of the network – on devices such as smartphones and IoT devices.As enterprise organizations look to extend their corporate digital channel strategies involving websites with rich media and personalized content, it is vital to have a strong resiliency strategy.Deploying a combination of cloud and edge services can help by: reducing unplanned downtime; improving security and performance; extending the benefits of multi-cloud infrastructure; speeding application development and delivery; and improving user experience.To read this article in full, please click here

CEO Succession at Internet Society – Status update (June 2018)

This is a quick update on the CEO Succession process at the Internet Society (ISOC). For background, please check my previous notes to the community.

As you know,  the application window for potential candidates for ISOC’s CEO position closed in early April. Let me update you on where we are in the process.

The process for selecting a new CEO for ISOC is progressing well and is on track. As anticipated, and as a consequence of the broad appeal of the role, the open call for applicants resulted in a significant amount of interest from all around the world. The Board received more than one hundred applications from candidates with a diverse set of backgrounds in business and the private sector, government, the technical community, the global NGO space, and the wider Internet community.

The strength and quality of the applications has been very high and it has been an incredibly tough challenge to identify and evaluate the most suitable candidates for this role from such a large and qualified pool of talent and experience.

Nevertheless, given the importance that the CEO position holds for both ISOC and the Internet as a whole, the deliberation by the Board has been Continue reading

Use Satellite 6 as an Inventory Source in Ansible Tower

Ansible-Sat

 Welcome to another entry in the Getting Started series! In this post we’ll talk about how to use Red Hat Satellite 6 as an inventory source within Ansible Tower. A common scenario we see is the use of Satellite 6.3 to manage Red Hat Enterprise Linux infrastructure, which makes adding Red Hat Ansible Tower to the existing environment a snap.

First, Create a User in Satellite

Ansible Tower will need to authenticate to Satellite, so create a user with an integration role that has the permissions needed to manage inventory. The permissions needed are:

Resource Permission Access Type
Fact value view_facts Read Satellite Server facts.
Host view_hosts  Read Satellite Server hosts.
Host group view_hostgroups  View Satellite Server host groups.

Once you’ve created your user, log in to the Tower host.

Create Credential in Tower With the Satellite User

Navigate to Settings >> Credentials in Tower and create a new credential.

Ansible-Tower-Sat-6-Screen-1

The credential type can be found in the credential type list:

Ansible-Tower-Sat-6-Screen-4
 

Once you select ‘Red Hat Satellite 6’, the field to add the Satellite URL will be available:

Ansible-Tower-Sat-6-Screen-6

Add New Inventory

With the Satellite server prepared and the credential in place within Tower, all that’s left Continue reading

A Wireless Brick In The Wall

I had a very interesting conversation today with some friends about predictive wireless surveys. The question was really more of a confirmation: Do you need to draw your walls in the survey plan when deciding where to put your access points? Now, before you all run screaming to the comments to remind me that “YES YOU DO!!!”, there were some other interesting things that were offered that I wanted to expound upon here.

Don’t Trust, Verify

One of the most important parts of the wall question is material. Rather than just assuming that every wall in the building is made from gypsum or from wood, you need to actually go to the site or have someone go and tell you what the building material is made from. Don’t guess about the construction material.

Why? Because not everyone uses the same framing for buildings. Wood beams may be popular in one type of building, but steel reinforcement is used in other kinds. And you don’t want to base your predictive survey on one only to find out it’s the other.

Likewise, you need to make sure that the wall itself is actually made of what you think it is. Find Continue reading

A Quadruple-Provider Vagrant Environment

In October 2016 I wrote about a triple-provider Vagrant environment I’d created that worked with VirtualBox, AWS, and the VMware provider (tested with VMware Fusion). Since that time, I’ve incorporated Linux (Fedora, specifically) into my computing landscape, and I started using the Libvirt provider for Vagrant (see my write-up here). With that in mind, I updated the triple-provider environment to add support for Libvirt and make it a quadruple-provider environment.

To set expectations, I’ll start out by saying there isn’t a whole lot here that is dramatically different than the triple-provider setup that I shared back in October 2016. Obviously, it supports more providers, and I’ve improved the setup so that no changes to the Vagrantfile are needed (everything is parameterized).

With that in mind, let’s take a closer look. First, let’s look at the Vagrantfile itself:

# Specify minimum Vagrant version and Vagrant API version
Vagrant.require_version '>= 1.6.0'
VAGRANTFILE_API_VERSION = '2'

# Require 'yaml' module
require 'yaml'

# Read YAML file with VM details (box, CPU, and RAM)
machines = YAML.load_file(File.join(File.dirname(__FILE__), 'machines.yml'))

# Create and configure the VMs
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|

  # Always use Vagrant's  Continue reading

Hackathon@AIS: Testimonies of the Fellows

The Hackathon@AIS is a yearly event, in its second year, aimed at exposing engineers from the Africa region to Open Internet Standards Development. This year, the event was held in Dakar Senegal at the Radisson Blu Hotel, from 9-10 May 2018, during the Africa Internet Summit (AIS-2018).

The event was attended by more than 75 engineers from 15 countries including 11 fellows who were supported to attend the event.

We are happy to share the testimonies of  the fellows who attended the Hackathon@AIS.

Adama Assiongbon

Hackathon@AIS has been a very good and enriching experience for me because it is a meeting of ICT sharing especially with the IPWAVE workshop which is a technology of the near future where we will be ready on the African continent to implement this technology and bring more to the development of the continent. It is up to us the beneficiaries of Hackathon@AIS to bring a plus to our communities. The idea of Hackathon is very beneficial for the development of Africa. Thank you AFRINIC and ISOC.
