SOFTWARE WATCH | Green Tea, Anyone?
Scientists who have unlimited hardware budgets, a dedicated IT staff versed in the arcana of networks, and lots of time on their hands probably find setting up a computer cluster a breeze. Everyone else knows it's difficult and expensive.
A new Java software program called GreenTea (www.greenteatech.com) offers an alternative. Instead of a cluster, GreenTea works as a peer-to-peer client, chopping large computing tasks into smaller, more workable fragments, each of which runs on one peer. Researchers have only to set up a simple network and then install the software, making the system simpler to install and easier to administer, though probably less efficient, than a standard cluster. And because GreenTea is Java-based, peers can run Linux, Mac OS, or Microsoft Windows.
Chief programmer Chris Xie says he will offer limited free phone help to scientists in need, under certain conditions: "If...
