Supercomputer Becomes Massive Router For Global Radio Telescope

Posted by Soulskill on Tuesday July 23, 2013 @06:13PM from the go-big-or-go-home dept.

Nerval's Lobster writes "Astrophysicists at MIT and the Pawsey supercomputing center in Western Australia have discovered a whole new role for supercomputers working on big-data science projects: They've figured out how to turn a supercomputer into a router. (Make that a really, really big router.) The supercomputer in this case is a Cray Cascade system with a top performance of 0.3 petaflops — to be expanded to 1.2 petaflops in 2014 — running on a combination of Intel Ivy Bridge, Haswell and MIC processors. The machine, which is still being installed at the Pawsey Centre in Kensington, Western Australia and isn't scheduled to become operational until later this summer, had to go to work early after researchers switched on the world's most sensitive radio telescope June 9. The Murchison Widefield Array is a 2,000-antenna radio telescope located at the Murchison Radio-astronomy Observatory (MRO) in Western Australia, built with the backing of universities in the U.S., Australia, India and New Zealand. Though it is the most powerful radio telescope in the world right now, it is only one-third of the Square Kilometer Array — a spread of low-frequency antennas that will be spread across a kilometer of territory in Australia and Southern Africa. It will be 50 times as sensitive as any other radio telescope and 10,000 times as quick to survey a patch of sky. By comparison, the Murchison Widefield Array is a tiny little thing stuck out as far in the middle of nowhere as Australian authorities could find to keep it as far away from terrestrial interference as possible. Tiny or not, the MWA can look farther into the past of the universe than any other human instrument to date. What it has found so far is data — lots and lots of data. More than 400 megabytes of data per second come from the array to the Murchison observatory, before being streamed across 500 miles of Australia's National Broadband Network to the Pawsey Centre, which gets rid of most of it as quickly as possible."

  OK, I may be too pedantic, but a 747 full of DVDs is just large storage, wildly different from large bandwidth.
  When you stream something, the data is immediately ready for processing as it comes (provided it's structured with that goal in mind). On the other hand, a 747 full of DVDs is data that must be read before it's ready for processing, and the average DVD read speed is more or less 100 Mbps, maybe a bit more than that but not by much. Throw time spent writing those DVDs into the mix and you'll get a shitty bandwidth, if you really want to go as far as calculating a bandwidth equivalent.
  Let's assume fly time is zero, just for kicks. Now for a DVD it takes you 10 minutes to write it (at high speeds) and 10 minutes to read it, that's 20 minutes per DVD. Say you can write/read 100 DVDs at the same time, that's roughly 430 GB every 20 minutes, that's roughly equivalent to a bandwidth of 367 MB/second. That's provided all DVDs are readable and you have tens of people you allocate to this project.

No need to make any assumptions about zero fly time, that is just latency, which all communication methods have to some varying degree.

A lot of the analysis waits to be done once a year anyway, as the statistics are useless doing it one day at a time and a long observing period is needed.

  Even more than that, *all* of it is potentially important. As I understand it phased arrays pretty much require the whole signal from all the antennas to get the benefit of having the antennas at all, it's not until *after* the signals are combined and processed that you can weed out the data you're not interested in. In fact based on 20s of reading on phased arrays I get the impression that the multi-directionality ability, etc. is likely determined by the transformation function you use to combine the raw data, so the same raw data can create "images" of various directions.

  Traditionally phased array was done by feeding the raw signals to a central point and then the "processing" is analog (circuits, not algorithms). The output is a single signal that contains the desired "image" which then goes into an A/D. At any time you only can look at the data in one way, since the raw data is not captured (raw being the data from each individual antenna).
  That works great for a radar on a ship where the antennas are all next to each other and where you can just rapidly steer back and forth, or where you are only tracking a single point and just don't want to use servos to do it. When the antennas are spread across a large area then you can't just run antenna feeds directly into a central box due to signal loss (even with amplification). It also doesn't work if you want to capture wideband data and look at all directions simultaneously after the fact. For that you need to digitize every antenna feed, and you also need an absolute time reference (which means lots of atomic clocks unless the sites are close enough to share a reference).

  Correlation is just simply a multiplication of all the signals from a single antenna pair called a baseline that results in a combined signal from a single beam or part of the sky. An interferometric telescope like the MWA has lots of baselines that mimic the collecting are of a very large dish without having to build a dish. The MWA is in fact using a combination of FPGA's and GPU's to form and correlate the signal from the array. It's my understanding its all very parallel in nature. The Pawsey part is simply being used as an archive for the data which is also used to push data to other archives.

  The correlators are done in specific hardware and not general purpose computers (using FPGAs in this case I think). But the real-time computer has to handle calibration against over 100 calibration sources and apply a ionosphere model to correct the data for correlations. Data is binned into 8 second segments, so all of the calculations have to be done in 8 seconds. Except they already have done extensive work on creating GPU algorithms for this, and have a setup with 64 GPU nodes to do such calculations. It wasn't just about speed, but they had total power limits too due to that being on site in the middle of nowhere.
  Of course this is all irrelevant to the Cray computer discussed above, which is not the on-site real time processing computer, it is instead a large computer installation in a suburb of Perth. This computer is not dedicated to processing of MWA data 24/7, and like most supercomputer centers, computing time is shared among several projects. You can't replace this with just a small cluster, as much as any other large time share computer that is actually being used can't be replaced by a smaller cluster.

You create those N virtual antennas by combining the input signals from the M physical antennas in N different ways. The combined signals are of much lower bandwidth than the incoming signals. Hence you could have people at university A looking at one place in the sky, the people at university B simultaneously looking at a different place in the sky, and have both of them receiving real-time signals.

It doesn't use the NBN. That's an optical access network for residential housing and small business with an access rate of 100Mbps. It uses AARNet -- Australia's Academic and Research Network -- which has installed multiple 100Gbps links across Australia for this project.
