Giving Out Grades For Exascale Efforts

Just by being the chief architect of the IBM’s BlueGene massively parallel supercomputer, which was built as part of a protein folding simulation grand challenge effort undertaken by IBM in the late 1990s, Al Gara would be someone whom the HPC community would listen to whenever he spoke. But Gara is now an Intel Fellow and also chief exascale architect at Intel, which has emerged as the second dominant supplier of supercomputer architectures alongside Big Blue’s OpenPower partnership with founding members Nvidia, Mellanox Technologies, and Google.

It may seem ironic that Gara did not stay around IBM to help this …

Worth Reading: High performance computing poised for change

There is a lot of change coming down the pike in the high performance computing arena, but it has not happened as yet and that is reflected in the current Top 500 rankings of supercomputers in the world. But the June 2017 list gives us a glimpse into the future, which we think will be as diverse and contentious from an architectural standpoint as in the past. —The Next Platform

Epyc win for AMD in the server security battle

While everyone is talking about the impressive performance potential and scale of AMD’s new Epyc server chips, overlooked in all the hoopla are the security features of the chip that may prove just as appealing.To start off, there is the tag team of Secure Memory Encryption (SME) and Secure Encrypted Virtualization (SEV). Secure Memory Encryption allows for full encryption of data stored in DRAM, and SEV allows individual virtual machines to be assigned a unique cryptographic key, thus isolating them from each other as well as the OS hypervisor and administrator layer. These functions are based on a hardware security processor attached to the memory controller with a 128-bit AES encryption engine.To read this article in full or to leave a comment, please click here

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
