IBM: 'We must build an Exascale computer before 2024' (video)
ASTRON has enlisted the help of IBM to lead a five-year, $43 million project to develop and build a supercomputer for the new Square Kilometer Array. The SKA is a $2.1 billion initiative to construct the world's largest radio telescope across a 3,000km strip of Australia or South Africa. It's hoped to be around 50 times as powerful as the dishes we currently point heavenward and will be used to examine the deepest reaches of space to learn more about the formation of the universe. When it goes live in 2024, it'll produce an Exabyte of data each day: twice as much information as there is traffic on the internet in the same period. Of course, no existing computer could handle the job, so Big Blue has a slim 12 years in which to turn nascent technologies like Nanophotonics, 3D chip stacking and phase change memory amongst others into a practical, workable Exascale computer. Its either that, or somehow daisy-chain 100 million PCs with enough power and cooling fans to keep it all working and hope for the best. If you'd like to know more, then head on past the break, although unfortunately it won't count as college credit.
ZFS to be the default file system in Leopard?
Steve is gonna be mad. You remember all those secret features that Leopard is supposed to have? And how Steve is going to wow us all with them at WWDC? Well, it looks like a little birdie, in the form of a big tech company's CEO, just let the whole world into one of those secrets. Mac Rumors points out that Jonathan Schwartz told an audience at a Sun event that the default filesystem in Leopard will be ZFS. We've known for awhile that Leopard will support ZFS, so that wasn't too shocking. This is the first anyone has heard about ZFS being the default filesystem for Leopard though. Why is this a big deal? Well, ZFS is a filesystem that Sun built from the groundup to address modern needs at the filesystem level. ZFS is a 128bit filesystem meaning it can theoretically hold up to 16 exabytes worth of information across multiple devices (an exabyte, in case you don't know, is about 1,073,741,824 gigabytes so the ZFS can hold 17,179,869,184 GB of data though that would be many, many harddrives). Wikipedia has a full explanation of ZFS, which highlights all the cool features.I suppose we'll all find out on Monday.
