6. Date: Thu, 22 Dec 2005 15:51:08 +0000 From: Roger Barlow To: babar-users@lists.man.ac.uk Subject: [BABAR-USERS] Manchester babar Dear Manchester BaBarians, 2 bits of good news. 1) easyroot works. I have carefully idiot-proofed it, and if I can make it work then anyone can. Today it gives access to a small farm, meaning you can run several jobs in parallel and speed up your tauuser analysis by an order of magnitude. Soon we will enable the rest of the existing BaBar farm. And before long we have the 1000 node Dell farm. For brief instructions see http://www.hep.man.ac.uk/u/roger/easyroot.html For full instructions see http://www.hep.man.ac.uk/u/jamwer/rootsrc.html 2) we have a new big disk, thanks to Sabah. 1.6 TB. We need to decide what to put on it (and what to call it.) Father Christmas has been busy... Roger
