SKA - no longer a troublesome mass-mailing computer virus

Filed Under: Uncategorized

In computer security history, the word Ska is most closely associated not with the musical genre that led to reggae, but with a widespread mass-mailing virus also known as Happy99.

The virus appeared right at the end of 1999, and became rampant during 2000.

Happily, that negative association has now been taken over by SKA, the Square Kilometre Array Telescope.

As its name suggests, the SKA will be - amongst other things - a grid of radio telescopes, comprising both dishes and arrays, in an area approximately 1km x 1km.

When finished, it's expected to have about 3000 dishes, each 15m in diameter, capable of moving and capturing data both individually and in precise synchronisation.

Whilst this won't give exactly the same results as a perfectly-formed dish 1000m in diameter, computer synthesis (interferometry) will get it impressively close.

After all, a steerable and perfectly-formed 1000m dish is - at least in 2012 - a practical impossibility, especially here on earth, where it would be subjected to the forces of gravity, weather and budget.

Over the weekend, the SKA Organisation, a not-for-profit headquartered out of Manchester, England, announced the final plans for the actual construction of the project.

The original concept called for a choice between South Africa and Australia (with New Zealand) as the location.

A dual-hosted solution was ultimately ratified. South Africa was identified as the preferred site, and now gets the lion's share of the grid; Australia and New Zealand will also build and host part of the grid, thus extending its baseline (its theoretical aperture) to 3000km.

The construction project will be completed in phases, with 10% finished by 2019 and the rest by 2023. This will let astronomers start producing their first results sooner.

According to the SKA Organisation:

* SKA will be 50 times more sensitive and 10,000 faster than the current best telescope.

* The telescope will address fundamental unanswered questions about our Universe, including how the first stars and galaxies formed after the big bang.

* The grid will require image processing power of 100 petaFLOPS (floating point operations per second).

* SKA will generate 10 gigabytes of data per second.

To put this into perspective, the fastest computer right now is the Japanese juggernaut "K", which can just sneak past 10 petaFLOPS on a good day, at maximum load, with a following wind.

Calling "K" a computer is something of a terminological simplification: it consists of 705024 CPU cores, fills 800 racks in a 50m x 60m pillarless room and has 1000km of cabling. At peak load, it uses 20MW of power.

Clearly, just the calculating-machine requirements of the SKA project are a bold undertaking - and that's before you start building thousands of individually-steerable radio dishes in the middle of the desert, as far from unwanted electromagnetic emissions as possible.

Oh, and before you take into account the computer security requirements of a computer system of that magnitude!

    This has nothing to do with botnets or security.

      Aren't you intrigued to hear about a distributed network - effectively, a single telescope - which will span two continents and require 10x more number crunching power in total than the world's current #1 supercomputer?

      Doesn't that make you think, "Wonder what hacking stories we might read about in or from the depths of the South African and Ozzie deserts in 10 years' time?"

      (In case not, I sneakily introduced the concept of security in the last sentence, so - technically, at least - your categorisation warning is have a heart, Sir!

    100 Petaflops? 99 Petaflops for anti-virus, 1 for productive processing?

    Nice advancement for basic and exotic radio astronomy, love it!

    Didn't Reggae lead to Ska?

    • Paul Ducklin · 1228 days ago

      Ska came after WW2 in the 1950s; reggae later, in the 1960s.

    I once accidentally infected my PC with happy99. I swore out loud the moment I saw the fireworks window on my screen.

    Shutdown, format, reload, I was not going to take chances

    Are you sure that SKA has disappeared? I've had 5 e-mails sent to me by "friends" that all have close to the same link inside them. I suspect that the website can run a javascript that goes thru you yahoo contact list and sends out more e-mails. Has anyone got good protection against this? My Webroot didn't catch it. Luckily, I closed that tab in my Firefox and ended up with about 50 e-mails sitting in my draft folder ready to be sent "from me".

      Ska/Happy99 doesn't send out emails containing links. The infected emails contain _only_ an attachment - the "happy99.exe" file which displays fireworks as a cover for its malicious activity.
