Of course, never assume what the PR office of a university releases makes any real sense, as this SLAC press release demonstrates.
Looks like a commonplace database search trick to throttle flow control in a faster than exp backoff by probing for the likely end-to-end flow rate at any time. The question is, is this a good enough “good enough” strategy?
Jim Gray, once again, was willing to provide me a bit of perspective on this.
I’ve been following the CalTech and CERN groups responsible for achieving what they claim is the “latest Land Speed Record” of 5.4 Gbps and a claimed throughput of 6.25 Gbps over an average period of 10 minutes, according to the announcement to the Internet 2 newslist on February 24th.
Of course, what does this mean? They claim that “best achieved throughput with Linux is ~5.8Gbps in point to point and 7.2Gbps in single to many configuration”. They claim they’re melting down the “hardware” at 6.6 Gbps. Is this true?
While we’re all oohing and ahhing over CalTech’s FastTCP bulk transfers and record busting using their new TCP congestion control – interesting paper (finally) by Jin/Wei/Low – contrast this with friendly rival Stanford’s protocol high-speed TCP that changes the fairness (I find it interesting and provides some new ideas). Are either likely to impact anyone’s use of the Internet in the next decade, anymore than studying cold fusion?
I’m struck by how all this “record busting” may be a mere sideshow in the scope of real Internet usage, especially given Microsoft Research’s own Jim Gray’s economic arguments against bulk transfers at Stanford a few months back.
Well, just for fun we followed Ben along as he entered and competed in the Synopsys Science and Technology Championship with his project The Perfect Eye and created a little video on the science fair experience (he took second prize in his catagory at the awards ceremony at Great America).
Since the project had the interest of some people in the San Jose Astronomy Association, a little notice on a local astronomy list mentioned the vid – and then the traffic started. Within one minute of posting, people were clicking and watching – thousands of views in less than a week, many repeat complete views. I had to allocate more bandwidth.
I guess everyone loves a science fair.
Wow, after a year of work with my old department at Cal doing a case study of technical issues in massive video production (MVP) for physics alumni outreach, lots of late nights, and crossing my fingers, it all paid off. I got an acceptance to the ACM SIGCHI Advances in Computer Entertainment Conference (ACE2004) to present the results of our work in Singapore in June.
I’ve never been to Singapore before, so I’m really excited. As CTO of ExecProducer, I’m proud of what we achieved over the last year technically. As a Berkeley physics alumna, I’m proud to have done a project with my department. And as a writer, I’m absolutely thrilled that they liked it.
Went to the 2004 First Robotics Regional Competition in Silicon Valley, held at San Jose State University. And it was awesome to see all these kids running their “bots” through the paces. Got some great footage, even though Los Gatos High School’s robot broke midway through competition.
Seeing the excitement, the fun, and the high-tech hijinks reminded me of the days when we were putting together workstations on-the-fly in a Berkeley workstation spin-out called Symmetric Computer Systems. I haven’t seen this kind of serious fun for a long time in the computer biz.
Maybe we should all be building bots…
Google put out a lunar job listing, for the person who really needs to get away from people.
So I went and asked Vint Cerf “Perhaps this is the first real use of interplanetary TCP?”. He laughed. I think you will too.
OK, I like Google. Always have I suppose, because it’s minimalist. And I like the logo – it’s kind of simple and childish, but it’s very Stanford. Yes, I know, I went to Berkeley, but my dad and brothers went to Stanford, so even if there’s a rivalry, it’s a friendly one. Besides, usually Berkeley gets the axe to grind – I’ll take a bear over a tree anyday.
Well, a miracle finally occurred – Sun and Microsoft announced today that they were going to kiss and tell. The long-running antitrust lawsuit and bad blood is now at an end. In fact, they are eager to spread their prosperous love!
All the world loves a lover, and no one should miss such a wonderful opportunity. So in the spirit of spreading more good news, I’d like to invite people to tune into a topical Internet TV in-depth technology commentary program we’ve been working on at TeleMuse Networks called In the DataCenter, where we will find out that Making Up isn’t Hard to Do.
