DESCRIPTION:Prof. Johannes Gehrke\, Department of Computer Science\, Corne
 ll University\, invited by Karl Aberer\nAbstract:\nMassively Multiplayer O
 nline Games (MMOs) are large simulations of virtual worlds where players c
 an interact with each other and other non-player characters. Current MMO a
 rchitectures execute the actions from the players and the associated game 
 logic at the servers of the company hosting the game\, resulting in huge s
 calability challenges. Business transaction processing faces similar chall
 enges in that the database server has to scale to extremely high transacti
 on rates.\n\nIn this talk\, I will describe a novel server-less architectu
 re for MMOs and scalable transaction processing. Our system is based on op
 timistic concurrency control separated into components that each can scale
  separately with the load on the system. I will show results from applying
  the architecture to MMOs and also describe ongoing work on apply the idea
 s to multi-tenant and elastic transaction processing in the cloud.\n\nBio:
 \nJohannes Gehrke is a Professor in the Department of Computer Science at 
 Cornell University. Johannes' research interests are in the areas of datab
 ase systems and data mining. Johannes has received a National Science Foun
 dation Career Award\, an Arthur P. Sloan Fellowship\, an IBM Faculty Award
 \, the Cornell College of Engineering James and Mary Tien Excellence in Te
 aching Award\, and the Cornell University Provost's Award for Distinguishe
 d Scholarship. He co-authored the undergraduate textbook Database Manageme
 nt Systems (McGrawHill (2002)\, currently in its third edition)\, used at 
 universities all over the world. Johannes is also an Adjunct Faculty at th
 e University of Tromsø in Norway. He is spending the 2010/2011 academic y
 ear visiting the Max Planck Institute for Software Systems in Germany.\n\n
 Johannes was Program co-Chair of the 2004 ACM International Conference on 
 Knowledge Discovery and Data Mining (KDD 2004)\, and Program Chair of the 
 33rd International Conference on Very Large Data Bases (VLDB 2007). From 2
 007 to 2008\, he was Chief Scientist at FAST\, A Microsoft Subsidiary.
