SC16 for HPC Programmers: What to Watch

An event as large and diverse as the annual Supercomputing Conference (SC16) presents a daunting array of content, even for those who specialize in a particular area inside the wider HPC spectrum. For HPC programmers, there are many sub-tracks to follow depending where on the stack on sits.

The conference program includes a “Programming Systems” label for easily finding additional relevant sessions, but we wanted to highlight a few of these here based on larger significance to the overall HPC programming ecosystem.

HPC programmers often have special considerations in how they program that other fields do not. For example, nothing …

Scoring the DNS Root Server System

The process of rolling the DNS Root’s Key Signing Key of the DNS has now started. During this process there will be a period where the root zone servers’ response to a DNS query for the DNSKEY resource record of the root zone will grow from the current value of 864 octets to 1,425 octets. Does this present a problem? Let’s look at the DNS Root Server system and score it on how well it can cope with large responses. It seems that awarding stars is the current Internet way, so let’s see how many stars we’ll give to the Root Server System for their handling of large responses.

SC16 live real-time weathermaps

Connect to https://inmon.sc16.org/sflow-rt/app/sc16-weather/html/ between now and November 17th to see a real-time heat map of the The International Conference for High Performance Computing, Networking, Storage and Analysis (SC16) network.

From the SCinet web page, "The Fastest Network Connecting the Fastest Computers: SC16 will host the most powerful and advanced networks in the world – SCinet. Created each year for the conference, SCinet brings to life a very high-capacity network that supports the revolutionary applications and experiments that are a hallmark of the SC conference."

The real-time weathermap leverages industry standard sFlow instrumentation built into network switch and router hardware to provide scaleable monitoring of the SCinet network. Link colors are updated every second to reflect operational status and utilization of each link.

Clicking on a link in the map pops up a 1 second resolution strip chart showing the protocol mix carried by the link.

OSiRIS (Open Storage Research Infrastructure) is a "distributed, multi-institutional storage infrastructure that lets researchers write, manage, and share data from their own computing facility locations."

BlackNurse attack: 1 laptop can DoS some firewalls, bring down big servers

An attacker doesn’t need an IoT botnet or massive resources for a denial of service attack to knock large servers offline; researchers warned that all it takes is one laptop for a “BlackNurse” attack to bring vulnerable Cisco, SonicWall, Palo Alto and Zyxel firewalls to their knees.Danish researchers at the Security Operations Center of telecom operator TDC described BlackNurse as a low bandwidth Internet Control Message Protocol (ICMP) attack that “is capable of doing a denial of service to well-known firewalls.”In their report (pdf), the researchers wrote:To read this article in full or to leave a comment, please click here

Unable to access Cisco ASA through AnyConnect VPN?

How Does Internet Work - We know what is networking

I stepped on this issue few weeks ago. I was implementing a new ASA Firewall solution, first time for me with software newer than version 8.4.2 It seems that all those stories about changes in the NAT logic after that version were true. This is what I found out about ASA packet processing. Configuration was really straightforward and everything worked fine except one thing. When connected remotely using Cisco AnyConnect I was able to access all devices inside the network (inside ASA firewall), but not the ASA itself. I wasn’t able to connect with SSH nor with ASDM. I, of course,

Pascal GPUs On All Fronts Push Nvidia To New Highs

Chip maker Nvidia was founded by people who loved gaming and who wanted to make better 3D graphics cards, and decades later, the company has become a force in computing, first in HPC and then in machine learning and now database acceleration. And it all works together, with gaming graphics providing the foundation on which Nvidia can build a considerable compute business, much as Intel’s PC business provided the foundation for its Xeon assault on the datacenter over the past two and a half decades.

At some point, Nvidia may not need an explicit link to PC graphics and gaming …

Docker Online Meetup #46: Introduction to InfraKit

In case you missed it, Solomon Hykes (Docker Founder and CTO) open sourced InfraKit during his keynote address at LinuxCon Europe in Berlin last month. InfraKit is a declarative management toolkit for orchestrating infrastructure built by two Docker core team engineers, David Chung and Bill Farner. Read this blog post to learn more about InfraKit origins, internals and plugins including groups, instances and flavors.

During this online meetup, David and Bill explained what InfraKit is, what problems it solves, some use cases, how you can contribute and what’s coming next.

There are many ways you can participate in the development of the project and influence the roadmap:

Star the project on GitHub to follow issues and development
Help define and implement new and interesting plugins
Instance plugins to support different infrastructure providers
Flavor plugins to support a variety of systems like etcd or mysql clusters
Group controller plugins like metrics-driven auto scaling and more
Help define interfaces and implement new infrastructure resource types for things like load balancers, networks and storage volume provisioners

Check out the InfraKit repository README for more info, a quick tutorial and to start experimenting — from plain files to Terraform integration to building a Zookeeper Continue reading
