TITLE:
Designing Computer Systems with MEMS-Based Storage
http://lcs.web.cmu.edu/research/MEMS/index.html
ABSTRACT:
For decades the RAM-to-disk memory hierarchy gap has plagued computer
architects. An exciting new storage technology based on
microelectromechanical systems (MEMS) is poised to fill a large portion of
this performance gap, significantly reduce system power consumption, and
enable many new applications. This talk will explore the system-level
implications of integrating MEMS-based storage into the memory hierarchy.
Results show that standalone MEMS-based storage reduces I/O stall times by
4-74X over disks and improves overall application runtimes by 1.9-4.4X.
When used as on-board caches for disks, MEMS-based storage improves I/O
response time by up to 3.5X. Further, the energy consumption of MEMS-based
storage is 10-54X less than that of state-of-the-art low-power disk
drives. The combination of the high-level physical characteristics of
MEMS-based storage (small footprints, high shock tolerance) and the
ability to directly integrate MEMS-based storage with processing leads to
such new applications as portable gigabit storage systems and ubiquitous
active storage nodes.
BIO:
Steve Schlosser is a third-year graduate student in Electrical and
Computer Enginneering. His research interest is in novel storage devices
and their effect on systems of the future. His undergraduate degree is
also from CMU, and so he is well into his seventh year in Pittsburgh.
