Now a good Linux distro for it would be ....._____?
yum yum rasberry pi(e).
I’m still waiting for my *1*. What’s their secret?
Where did you order it from?
A few weeks ago I ordered mine from MCM Electronics, had it in my hands in about a week.
What is a *1*?
awesome- would this make a good web and database server?
Didn't know raspberries urinated.

“Where did you order it from?”
RC Online, months ago. Perhaps I should consider another supplier.
Oops, RS Online.
Suppose 2 Raspberry Pies were joined together to make a small super computer. What would it be equivalent to? How about 4 Pies? How many would it take to create something that is comparable to a 3rd Generation Intel® Core i7-3770 processor (up to 3.90 GHz)?
As one with nearly 30 years in the biz, the last decade in HPC (high performance computing; aka “supercomputing”)....I can tell you that this is nothing more than an interesting toy, NOT a true HPC cluster. Not even close.
Very true... the massive cabling alone assures that. Nevertheless, this is a fascinating project.
There’s nothing novel here. People have “clustered” PS3’s and Nintendo’s, for God’s sake. Clustering alone does not a supercomputer make.
HPC....high performance computing, aka “supercomputing”....a term no one in the industry uses any more, by the way....is 99% used for sophisticated modeling. Clusters are monstrous modeling machines. Weather models, nuke models, modeling protein folding, modeling oil reservoirs....you name it. They use the latest, greatest, hottest, fastest processors on the market. They use Infiniband as the communication fabric; ultra-low latency, super high message rates, performance at scale (to thousands of nodes....a node=a server), etc. These are big, expensive beasts that do remarkable calculations for remarkable science. For a bunch of dweebs to wire up some toy computers and claim it’s a “supercomputer” is worse than laughable.....it’s an insult to the intelligence to anyone in the field; anyone who uses this technology to solve huge, real world problems.
In sum.....it’s a pathetic little joke to get their sad little names in the paper.
You know, I was not going to reply to your post, agreeing with it completely ... “There’s nothing novel here.”
Reading it a second time on my “ping list”, though, inspires me to note one thing that is really novel: that the cost of this Raspberry Pi unit dramatically lowers the cost of the effort to create a cluster like this. That is clearly novel, I believe.
As a veteran of many years in the supercomputing biz, here’s the thing: Cost is but one factor. What’s far more important: What is the task you are trying to work on, to pursue? What problem(s) are you trying to solve?
I’ll absolutely, positively guarantee you this.....my clients would laugh this off as a toy and then get back to real business. They deal with serious problems, serious science, and they have no truck with such bulls**t. DOE labs, major universities, govt. agencies, etc. These are the heavy hitters, and I know the technologies they need.
This cute little experiment ain’t it.
