The students who worked on summer research projects with professor Bob Keller and professor Z Sweedyk will discuss their work.

Students who worked on summer research projects with Professor Stone and Professor O’Neill will present their work.

Andrew Gordon, from USC’s Institute for Creative Technologies, will be speaking at Pomona College. HMC colloquium students are expected to attend this talk.

I will talk about Cumulus, a system I have built for efficiently storing backups of data from end-user computers to “cloud storage systems”—services that offer to store data for customers over the Internet, generally at a flat rate per gigabyte of data stored and transferred. For portability, Cumulus is restricted to only a simple get/put interface to the remote storage, but I show that this restriction imposes only a low overhead in terms of storage, bandwidth, and cost—even compared with more complex approaches. Cumulus achieves this by aggregating small files together for storage and incorporating ideas from log-structured file systems. I may also talk about research and graduate school more generally.
