Rise of China, Real-World Benchmarks Top Supercomputing Agenda
The United States for years was the dominant player in the high-performance computing world, with more than half of the systems on the Top500 list of the world’s fastest supercomputers being housed in the country. At the same time, most HPC systems around the globe were powered by technologies from such major US tech companies as Intel, IBM, AMD, Cray and Nvidia.
That has changed rapidly over the last several years, as the Chinese government has invested tens of billions of dollars to expand the capabilities of the country’s own technology community and with a promise to spend even more …

Cloudflare Crypto Meetup #5: February 28, 2017
Come join us on Cloudflare HQ in San Francisco on Tuesday, Febrary 28, 2017 for another cryptography meetup. We again had a great time at the last one, we decided to host another. It's becoming a pattern.
We’ll start the evening at 6:00p.m. with time for networking, followed up with short talks by leading experts starting at 6:30p.m. Pizza and beer are provided! RSVP here.
Here are the confirmed speakers:
Deirdre Connolly
Deirdre is a senior software engineer at Brightcove, where she is trying to secure old and new web applications. Her interests include applied cryptography, secure defaults, elliptic curves and their isogenies.
Post-quantum cryptography
Post-quantum cryptography is an active field of research in developing new cryptosystems that will be resistant to attack by future quantum computers. Recently a somewhat obscure area, isogeny-based cryptography, has been getting more attention, including impressive speed and compression optimizations and robust security analyses, bringing it into regular discussion alongside other post-quantum candidates. This talk will cover isogeny-based crypto, specifically these recents results regarding supersingular isogeny diffie-hellman, which is a possible replacement for the ephemeral key exchanges in use today.

Upcoming Webinar: Open Networking for Large Scale Networks
Shawn Zandi and I are doing a two part webinar over at ipspace.net—
Most modern data centers are still using vendor-driven “future proof” routers and switches with offering lots of (often unnecessary) capabilities. To build large, however, it is often better to build simple—radically simple. This webinar will cover the design components involved in building a data center or cloud fabric using a single, disaggregated device—the way some hyperscale and web scale operators build their networks. The first live session of the webinar will consider the benefits of disaggregated switch, focusing on the components, sources, and challenges in using disaggregated hardware and software in data center fabrics. The second live session will focus on the topologies and design concepts used in large scale data center fabrics using a single switching device as a leaf, spine and superspine switch.

IPTables: Matching A GRE packet based on tunnel key
I was trying to figure out a way to match packets with a certain GRE key and take some action. IPTables does not provide a direct solution to this problem but has the u32 extension modules that can be used to extract 4 bytes of the IP header and match against a pattern. So, I … Continue reading IPTables: Matching A GRE packet based on tunnel key
One Small Shop, One Extreme HPC Storage Challenge
Being at the bleeding edge of computing in the life sciences does not always mean operating at extreme scale. For some shops, advancements in new data-generating scientific tools requires forward thinking at the infrastructure level—even if it doesn’t require a massive cluster with exotic architectures. We tend to cover much of what happens at the extreme scale of computing here, but it’s worth stepping back and observing how dramatic problems in HPC are addressed in much smaller environments.
This “small shop, big problem” situation is familiar to the Van Andel Research Institute (VARI), which recently moved from a genomics and …

Adventures in GELF
If you are running apps in containers and are using Docker’s GELF logging driver (or are considering using it), the following musings might be relevant to your interests.
Some context
When you run applications in containers, the easiest logging method is to write on standard output. You can’t get simpler than that: just echo, print, write (or the equivalent in your programming language!) and the container engine will capture your application’s output.
Other approaches are still possible, of course; for instance:
- you can use syslog, by running a syslog daemon in your container or exposing a /dev/log socket;
- you can write to regular files and share these log files with your host, or with other containers, by placing them on a volume;
- your code can directly talk to the API of a logging service.
In the last scenario, this service can be:
- a proprietary logging mechanism operated by your cloud provider, e.g. AWS CloudWatch or Google Stackdriver;
- provided by a third-party specialized in managing logs or events, e.g. Honeycomb, Loggly, Splunk, etc.;
- something running in-house, that you deploy and maintain yourself.
If your application is very terse, or Continue reading
