back to article Students smash competitive clustering LINPACK world record

Enormous happenings at the ISC17 Student Cluster Competition, where students from the Friedrich-Alexander-Universitat (FAU) broke the student cluster competition world record for HPL (LINPACK). This gives the home court German team the coveted Highest LINPACK award. This marks the first time a German team has won a major …

    Are you really just students who "guess" that the bus is overloaded?

    And am I reading this right, in that it's just a competition to slap a machine together without such knowledge and put as much stuff in as you can until you find the sweet spot?

    I find nothing technically interesting in either.

      WTF?

      Missing the point

      You couldn't be more wrong. If you have the time, read the other articles about these competitions. These kids spend months learning how to design a system and optimize the applications for it - while staying under the 3,000 watt power cap.

      It's not trial and error, more like testing permutations of hardware, software optimization, and then discovering the best combination. This is highly technical work, particularly for undergraduate students.

      Take another look at what they're doing before passing judgement.

        Besides, what you learn in theory during lectures is not always what happens in reality. Modern HPC architectures are complex beast, far more complex than the Cray J932 on which I did my first serious HPC work: that was a shared memory set-up with no processor caches, and 32 identical vector processing CPUs. Predicting what is would do on different workloads was hard enough, but it is much harder with the current mix of multi-core CPU, GPU, and all manner of buses and caches working at different speeds that make up a modern cluster.

        And anyway, this kind of competition is just fun!

    How many P100s could you stick onto an AMD EPYC processor ? (And how big would the case and PSU need to be to handle them all !!! )

    Dear Mr. Dan Olds

    Please do not put 'lol' in future articles, it looks ridiculous.

      Re: Dear Mr. Dan Olds

      Yeah, you make a good point. I just wanted to point out that I was trying to be funny with that comment - not serious. But if I have to point it out by inserting a "lol", then it's not funny enough to stand on it's own.

    Sacasm...

    This marks the first time a German team has won a major performance award on their home soil and is likely to result in the declaration of a national holiday featuring parades and a statue raising in their home town of Nuremburg.

    Why the sarcasm? This is quite an achievement for some students; >99% of the readership of this Esteemed Organ wouldn't be capable of doing this.

      Joke

      Re: Sacasm...

      It is always easy to smash, in theory, anybody can do better, the thing is, go do better, Mr. article author, love to see you perform better.

      Why no Windows ? Cost is not a concern, if I understand this correctly ... why no Windows ? oh, shit, I should know this, Windows cannot scale above a core ... or was it a thread ?

      Unhappy

      Re: Sacasm...

      NO sarcasm meant at all!!! I was trying to give it a 'sports caster' like spin. Sorry if I missed the mark. I'm very happy for the German team and their accomplishments. And I'll be cheering them on when they compete in the US later this year.

    Re: Sarcasm, I agree, came to think about it, they have, for good reasons, a statue of Zuse, the inventor of the modern computer.

    PS. Anything about the reaction to the first time a British team has won a major performance award on their home soil.
