Visit my new webpage at: University of Toronto where I have started my Ph.D. studies.

Advisor:

• Dilma Menezes da Silva

My main research interests are:

• Operating Systems in general
  • Design and Infra-Structure
  • Scalalable Algorithms
  • File Systems
  • Memory Management
• Distributed Systems
• Parallel Computing

Research

• K42 File System (KFS). My main research project is the development of the K42 File System for the Linux Kernel. The K42 operating system is a research operating system, which my advisor, Dilma, is currently working on along with some of other researches at IBM. Their intent is to make a high-performance, scalable and flexible operating system for multiprocessors.

  Read more about some of KFS' objectives at our KFS TWiki page.

• My Qualification Proposal (in portuguese). In this text, I describe the research project we will pursue. It is entitled: Flexibility in a Componentized File System.

• My qualification presentation (in portuguese). This is the presentation used during my qualification exam. Here I try to sum up all the ideas proposed in the qualification text (see above).

• Hurricane File System presentation (in portuguese). This presentation outlines the most influential work in my research, a flexible object-oriented file system for large-scale shared memory multicomputers.

• Inferno OS presentation (in portuguese), that I presented during Distributed Operating Systems course.

Publication

• Livio Soares, Orran Krieger, Dilma Da Silva: "Meta-data Snapshotting: A Simple Mechanism for File System Consistency", in Proceedings of SNAPI'03 (International Workshop on Storage Network Architecture and Parallel I/O).

  It is also available on the K42 web page here, and on the SNAPI page here.

Open Source Projects

• K42
  K42 is a new research operating system for cache-coherent multiprocessors. See the web-page for more information on the project. My involvement with K42 has to do with my master's research, and is focused on building a flexible and efficient file system for both K42 and Linux operating systems.

• Compressed Caching in Linux VM
  This project introduces compression inside Linux's VM, with automatic adaptivity. It is the main research of a friend, Rodrigo de Castro, here at the university.

• User Mode Linux
  This is a very cool project which enables you to run (and test) a Linux kernel as a simple Linux process. Very nice for everyone who does kernel hacking. I have made some minor contributions.

• Dillo Browser
  I'm one of the steady developers of this fun project. I also help to maintain the web page. Oh, and you can also see my list of current patches.

• Gaim
  This is a great Instant Messenger client. With this baby I can connect to ICQ (for friends), AIM (for advisor), Yahoo! (for friends at work), and IRC (for kernel discussion groups like #kernelnewbies).

• Mutt
  My favorite mail client. I simply adore this client, and nothing will make me want to switch to another... ever! (I used to say this too when I used Emacs' VM ;-).

• Emacs
  I am an avid user of this wonderful editor. I can't seem to program in anything else! This modest web page was completely constructed using Emacs.

• Debian
  My favorite GNU/Linux distro.
