DOE taps 6 firms for exascale computing research

The Department of Energy has awarded six tech firms a total of $258 million in funding for research and development into exascale computing. The move comes as the U.S. is falling behind in the world of top supercomputers.Energy Secretary Rick Perry announced that AMD, Cray, Hewlett Packard Enterprise, IBM, Intel and Nvidia will receive financial support from the Department of Energy over the course of a three-year period. The funding will finance research and development in three main areas: hardware technology, software technology and application development.Each company will provide 40 percent of the overall project cost in addition to the government funding. The plan is for one of those companies to be able to deliver an exascale-capable supercomputer by 2021. It’s part of the DOE’s Exascale Computing Project (ECP), which in turn is part of its new PathForward program, designed to accelerate the research necessary to deploy the nation’s first exascale supercomputers.To read this article in full or to leave a comment, please click here

On the ‘net: Interview on my network career

I was recently interviewed for a new network career site—

I started out building small networks on a lot of different technologies in the USAF, primarily Banyan Vines and Novell Netware, over Token Bus, Thicknet, and other technologies. We implemented a fiber backbone, and I helped replace the old physical switch telephone system main frame with a modern (at that time) SS7 based design. After this, I worked for a small Value Added Reseller around New York City, and then the ASME as a network administrator, then at BASF in the Advanced Technology Group. At this point my wife and I moved to Raleigh, and I started at Cisco TAC in the hardware team. From there I moved to the Routing Protocols team, then Global Escalation, and then into engineering in various roles around Cisco IOS Software and XR. After Cisco, I moved to Verisign Labs, where I primarily focused on security in a more research oriented role, then to Ericsson, working on IPOS, and now LinkedIn.

This looks like a great resource, worth following.

Static Routing configuration different ways

Today I am going to talk about the Static routing and default routing. Some of you already know about the both these but some of you guys are still not aware about this stuff. This article is basically for the starters in the Networking field.


Fig 1.1- Sample Static routing configuration

Let's talk about the IP routing first with the static routing. When using the ip route command, you can identify where packets should be routed to in two ways: 
  • The next-hop address 
  • The exit interface 
Way-1 :The Next-Hop Address
Router(config)#ip route 172.16.20.0 255.255.255.0 172.16.10.2
172.16.20.0 = destination network
255.255.255.0 = subnet mask 
172.16.10.2 = next-hop address
What does it means: To get to the destination network of 172.16.20.0, with a subnet mask of 255.255.255.0, send all packets to 172.16.10.2  

Way-2 :The exit interface
Router(config)#ip route 172.16.20.0 255.255.255.0 s0/0
172.16.20.0 = destination network 
255.255.255.0 = subnet mask s0/0 = exit interface
What does it means: To get to the destination network Continue reading

Worth Reading: What if we designed differently?

Imagine if the design of your electrical supply was optimised to apply the biggest possible voltage and current to anything that was plugged in. That would clearly be ridiculous! Imagine if the design of your kitchen tap was optimised to deliver as much water as possible at the highest possible pressure the moment you turned it on. That would clearly be ridiculous! Imagine if the design of your gas cooker was optimised to burn everything to a crisp as fast as possible in a white hot inferno. That would clearly be ridiculous! So, why have we optimised broadband to deliver as much bandwidth as possible? That’s clearly ridiculous! —CircleID

Announcing the Cloudflare Apps Platform and Developer Fund

Announcing the Cloudflare Apps Platform and Developer Fund

When we started Cloudflare we had no idea if anyone would validate our core idea. Our idea was what that everyone should have the ability to be as fast and secure as the Internet giants like Google, Facebook, and Microsoft. Six years later, it's incredible how far that core idea has taken us.

Today, Cloudflare runs one of the largest global networks. We have data centers in 115 cities around the world and continue to expand. We've built a core service that delivers performance, security, availability, and insight to more than 6 million users.

Democratizing the Internet

From the beginning, our goal has been to democratize the Internet. Today we're taking another step toward that goal with the launch of the Cloudflare Apps Platform and the Cloudflare Developer Fund. To understand that, you have to understand where we started.

When we started Cloudflare we needed two things: a collection of users for the service, and finances to help us fund our development. In both cases, people were taking a risk on Cloudflare. Our first users came from Project Honey Pot, which Lee Holloway and I created back in 2004. Members Continue reading

Lufthansa Systems taps Portworx for stateful containers

When Docker first (re) popularized the use of container-based infrastructure, there was a bit of discussion around the storage problems related to containers. Two startups came into being to try and resolve the issue: ClusterHQ and Portworx.While ClusterHQ flamed out, Portworx is still going strong and today announced a high-profile and interesting case study.To clarify exactly what Portworx does, users can use it to manage any database or stateful service on any infrastructure using any container scheduler, including Kubernetes, Mesosphere DC/OS and Docker Swarm. Portworx solves the five most common problems DevOps teams encounter when running containerized databases and other stateful services in production: persistence, high availability, data automation, support for multiple data stores and infrastructure, and security. As such, Portworx technology is ideally suited for solution verticals such as databases, messaging queues, continuous integration and continuous deployment (CI/CD), big data, and content management. To read this article in full or to leave a comment, please click here
