NASA - Most Powerful Eruption in the Universe Discovered
NASA - Most Powerful Eruption in the Universe Discovered: "This event was caused by gravitational energy release, as enormous amounts of matter fell toward a black hole. Most of the matter was swallowed, but some of it was violently ejected before being captured by the black hole. 'I was stunned to find that a mass of about 300 million suns was swallowed,' said Brian McNamara of Ohio University in Athens. 'This is as large as another super massive black hole.' He is lead author of the study about the discovery, which is in the January 6, 2005, issue of Nature. "

Automatic Locality-Improving Storage (ALIS)
Overview
Processor performance has increased at the phenomenal rate of 60 percent per year (Moore's Law), while disk access time, which is limited by mechanical delays, has improved by only about 8 percent per year. Further compounding the widening gap between processor and disk storage performance is the fact that disk capacity has doubled almost every year. As a result, it is increasingly difficult to use all of the available disk capacity effectively. Note, however, that although disk access time has been relatively stable, disk transfer rate has been increasing by about 40 percent per year.
In this research, we are exploring ways to exploit increasing processor performance, disk capacity, and sequential bandwidth to mask the growing performance gap between processor and disk storage. We have considered embedding processing power near the data (for example, on the disk adapter) to handle general-purpose processing offloaded from the host system. Our current interest is in reorganizing data to increase spatial locality, thereby improving disk performance. Our methodology is trace-driven simulation, and an ongoing part of this research is the collection and characterization of high-quality I/O traces."
