Since I am away this semester and nobody else has had the inclination to carry on the seminars, I'm now going to officially state that this unofficial group has been suspended until such time that someone steps up and wants to take on the (small) work of running it.
In other news, there is now a GSO group specially for CS students. It is officially funded with a substantial amount of capital (taken from student fees). Join the group to help decide what to spend the money on and to partake in the benefits.

2008-08-15 2PM-3PM, EB G11: Michael Hines on "Post-Copy Based Live Virtual Machine Migration Using Pre-Paging And Dynamic Self-Ballooning"
Michael Hines will be talking about his latest research in a department colloquium. While this isn't an "official" grad seminar talk, everyone is certainly invited to attend. Here's the abstract:
Time: Friday, August 15th, 2008 2:00 PM - 3:00 PM
Location: G-11 Conference Room Engineering Bldg.
Title: "Post-Copy Based Live Virtual Machine Migration Using
Pre-Paging And Dynamic Self-Ballooning"
ABSTRACT
We present the design, implementation, and evaluation of the post-copy
based method for the live migration of virtual machines across a
Gigabit LAN. Live migration is a mandatory feature of modern
hypervisors today. It facilitates server consolidation, system
maintenance, and lower power consumption. Post-copy refers to the
deferral of the ``copy" phase of live migration until the virtual
machine's CPU state
has already been migrated. This enables the migration daemon to try
different methods by which to perform the memory copy. With
post-copy, we seek the goal of a ``win-win'' by deterministically
guaranteeing at most the same migration time of the static, pure
stop-and-copy method. Post-copy also provides the downtime and
liveness benefits of pre-copy, without relying on an unbounded
iterative process. We facilitate the use of post-copy with a specific
instance of adaptive pre-paging (also known as adaptive remote
paging). Pre-paging is capable of eliminating all duplicate page
transmissions and removing any residual dependencies. Our algorithm is
able to minimize the number of page faults to less than 20% of the
Virtual Machine's writable working set. Finally, we facilitate both
the original pre-copy and post-copy schemes with the use of dynamic,
periodic self-ballooning. This prevents the migration daemon from
transmitting unnecessary free pages in the guest system. This also
noticeably speeds up both migration schemes with very negligible CPU
degradation to the processes running within the Virtual Machine. We
implement post-copy on top of the Xen Hypervisor and benchmark its
behavior against the existing pre-copy method.

2008-07-09 6:00PM-7:30PM, EB Q3: Calendaring Roundtable
I've been thinking about calendaring lately and we could have
another "roundtable" style discussion about calendaring in the CS
graduate student environment. If everyone's already allocated this
timeslot (2008-07-09 @6PM), maybe we can go ahead with a meeting about
using calendar tools.
I personally use Google calendar and hook it into my desktop calendar
software. I'd be interested in hearing about other solutions folks use
(from software-based solutions to paper-based to solutions to
neurologic-based solutions).

Next Talk: Mikhail Gofman on RBAC on 2008-03-19 at 6:30PM in EB G11
The next talk will be held (tomorrow) Wednesday, March 19, 2008 in the large conference room (EB G11 in the Engineering Building on the Binghamton University main campus).
Mikhail will talk about the research he's done for his MS, which he will be defending on Thursday (March 19).
The title of his talk is EFFICIENT POLICY ANALYSIS FOR ADMINISTRATIVE ROLE BASED ACCESS CONTROL.
Pizza and soda are planned to be made available. Donations (of a few dollars) are requested, but not required, for the consumption of food.

2008-02-21 (5PM-6PM), EB G11: Computing with Light
On Thursday, February 21, 2008, we will have the next BUCS talk. The talk will cover "Computing with Light" and show how one can solve NP-complete problems in polynomial time (and exponential space) using a photo copier.
