ABSTRACT

2007 Google Seattle Conference on Scalability:
Lustre File System
Speaker: Peter Braam, Cluster File Systems, Inc.

Lustre is a scalable open source Linux cluster file system that
powers 6 of the top 10 computers in the world. It is resold by HP,
SUN, Dell and many other OEM and storage companies, yet
produced by a small powerful technology company, Cluster File
Systems, Inc. This lecture will explain the Lustre architecture and
then focus on how scalability was achieved. We will address many
aspects of scalability mostly from the field and some from future
requirements, from having 25,000 clients in the Red Storm
computer to offering exabytes of storage. Performance is an
important focus and we will discuss how Lustre serves up over
100GB/sec today going to 100TB/sec in the coming years. It will
deliver millions of metadata operations per second in a cluster and,
write 10′s of thousands of small files per second on a single node. If
you like big numbers (but less than a Gogol) please come to this
talk. Read the rest of this entry »

ABSTRACT

Learn about New Zealand from two of their biggest open-source developers and evangelists (and who have naturally starred in The Lord Of The Rings.)

Sam Minnee and Sigurd Magnusson are two of the three founders of New-Zealand based "SilverStripe", a company and open source project with ten students participating in this year’s Google Summer of Code.

They will share wisdom learnt managing people in an open source project, share ideas from developing a rich web interface and templating system, and stories from wearing the ring of darkness.
Sigurd has been living and breathing free software since his teens in the 1990s, discovering a 486 with Redhad Linux could run Quake fast enough to frag others at LAN games. His grandma taught him BASIC and C and got him access to a precursor of New Zealand’s first ISPs, which culminated years later with founding SilverStripe, an open source web-development company bent on making fantastic applications to simplify building and managing websites. Having let a dozen others at SilverStripe surpass him at PHP, Sigurd has now been charged with building up the SilverStripe community and producing other things, like daughters.
Sam is the lead architect of SilverStripe and has challenged the manner in which software is constructed ever since he began programming in his teens. Armed with a degree in computer science and philosophy, Sam has been mentoring and guiding the development of a dozen coders, hundreds of websites, and hundreds of thousands of lines of code. He has a firm grasp on intelligently structuring code as well as producing useful, enjoyable system interfaces, particularly helpful in the challenge of making SilverStripe a great tool for building and managing websites.

ABSTRACT

This is the Google campus version of Stats 202 which is being taught at Stanford this summer. I will follow the material from the Stanford class very closely. That material can be found at www.stats202.com. The main topics are exploring and visualizing data, association analysis, classification, and clustering. The textbook is Introduction to Data Mining by Tan, Steinbach and Kumar. Googlers are welcome to attend any classes which they think might be of interest to them. Read the rest of this entry »

GeoDec: Enabling Geospatial Decision Making

Cyrus Shahabi
Cyrus Shahabi is currently an Associate Professor and the Director of the Information Laboratory (InfoLAB) at the Computer Science Department and also a Research Area Director at the NSF’s Integrated Media Systems Center (IMSC) at the University of Southern California.

ABSTRACT
The vision of GeoDec is to enable an information-rich and realistic 3-dimensional visualization and/or simulation of a geographical location (e.g., a city), rapidly and accurately. The idea is not just to allow navigation through a 3-D model, but to be able to ask queries and get information about the area seamlessly and effortlessly. Our main focus it to build tools to quickly and cheaply integrate, visualize, and analyze all aspects of a geographic region. The ability to create high-fidelity information-rich models of cities is critical for a wide variety of decision makers. For example, in the United States, GeoDec can be used by city managers, city planners, emergency response planners, and first responders. Read the rest of this entry »
