Portable and Efficient Profiling for the JVM Using Bytecode Instrumentation ===========================================================================

When: Tuesday November 22, 2005, @17h15

Where: Institut für Wirtschaftsinformatik (IWI), Universität Bern, Engehaldenstrasse 8, 3012 Bern, Hörsaal 001

Speaker -------

Dr. Walter Binder, Laboratoire d'intelligence artificielle, EPFL

Agenda ------

17h15 - 18h15 Talk and Q/A Afterwards you are invited to a refreshment.

Abstract ========

Profiling complex, Java-based systems, such as e.g. middleware for service-oriented computing, is a tedious task, because most available profilers for Java cause excessive overhead or are not accurate enough. For instance, the exact profiler delivered with standard JDKs may cause overhead up to factor 4000, while the complementary sampling profiler does not generate accurate profiles. As another drawback, existing profiling support in standard JVMs require profiling agents to be written in native code, contradicting the Java motto "write once, run anywhere".

Bio ===

Dr. Walter Binder is a researcher at the Artificial Intelligence Laboratory at EPFL since February 2003. He holds a M.S. (1997) and a Ph.D. (2001) in computer science from the Vienna University of Technology. Prior to his work at EPFL he worked for a software engineering company in Vienna, where he developed among other things the J-SEAL2 mobile object kernel, a Java-based component system offering operating system functions, strong security mechanisms, and support for mobile code. He also initiated the development of a resource management framework for Java. Moreover, he developed a Java-based operating system for embedded devices offering a high level of security and supporting remote maintenance and software deployment through mobile code. The focus of his recent research is on portable and accurate profiling techniques for virtual execution environments and on middleware for service-oriented computing. Walter Binder has published more than 40 refereed papers on his work. He received the Dimitris N. Chorafas Foundation 2000 Prize for Internet and Information Science.
