[pl-seminar] meet with Gary Sevitsky from IBM

[Ben Liblit <liblit@xxxxxxxxxxx>]

Gary Sevitsky of IBM TJ Watson Research Center will be visiting us on 
October 27 (Monday after next).  He will be giving a talk and is also 
interest in meeting with faculty and students.  Are you interested in 
meeting with him?  If so, please let me know soon.  I'll pass your names 
along to Cathy who will assemble his schedule within the next few days.
Feel free to forward to other grad students who might be interested, but 
who are not on <pl-chat> or <pl-seminar>.

Hi Ben,

I would like to follow up with arrangements for my visit on Oct. 27th.  

If there are faculty or students whom you think would be interested in talking with me please add them to my schedule.  Some people I thought of if there is time would be Tom Reps, Susan Horowitz, Bart Miller, and Charles Fisher.

Also, here is an abstract for the talk I am planning to give:

Title
Efficient Memory Usage in Java: Current Practices and Challenges

Authors
Nick Mitchell, Edith Schonberg, Gary Sevitsky (speaker)
IBM TJ Watson Research Center, Hawthorne, NY USA

Abstract
It is easy these days to build Java applications with large memory requirements – in fact it takes significant effort not to. It is common to see multi-gigabyte heaps with tens of millions of objects, where as much as 60-80% of the memory is the overhead of data representation. These systemic space inefficiencies are the combined result of local decisions made at many layers of application and framework code, along with limitations of the Java language and runtime. Poor use of memory has a significant impact on scalability, power consumption, reliability, and even application performance.  

In this talk we aim to raise awareness of the patterns and practices that lead to excessive memory consumption in Java. We present a sampling of patterns drawn from dozens of industrial applications in which our group has helped diagnose memory problems over the past eight years. The patterns are organized around common design problems such as modeling data types, representing relationships, and managing object lifetime. Mitigating memory problems will require a multifaceted approach, and may require new kinds of metrics, tools, optimizations, and language features. We sketch out some possible strategies for improving the state of memory usage, and give an overview of our memory analysis tool and design health methodology.

Looking forward to visiting.

Regards,
Gary
