nd treatment at a much faster speed."
The new device is expected to be a 256 dual quad-core node cluster computer with 1 petabyte of storage. A petabyte is a measure of digital information equivalent to 1 quadrillion bytes or 1,000 terabytes. (A common household computer or portable flash drive usually possesses storage capacity measured in gigabytes; a terabyte equals 1,024 gigabytes of data.)
The computer will be installed, tentatively in early 2009, in the university's Computational Science and Engineering Building. "We have a 1,000-square-foot room reserved for it, and the computer will fill it up," Winslow said. A vendor for the computer has not yet been selected.
The technological resource will be shared by more than a dozen faculty members affiliated with the Institute for Computational Medicine. Winslow predicts that it will also serve perhaps 100 other collaborators from the university's School of Medicine and Whiting School of Engineering and from other institutions.
Three Department of Biomedical Engineering faculty members who will be among the institute members using the computer to enhance their research are:
- Natalia Trayanova, who studies how dangerous
arrhythmias are initiated and maintained in the heart. The new computer
is expected to speed up her efforts to find the best ways to halt these
irregular heart rhythms with shocks from a defibrillator.
- Michael I. Miller, who compares the shape of brain structures
in images from healthy and diseased patients, looking for differences
that may lead to better diagnoses and treatments. Miller now uses linked
computers across the country to collect the resources to conduct this
research. When Miller gets access to the new Johns Hopkins computer,
Winslow said, work that now takes months to accomplish by cross-country
connections should take only days to complete.
- Rachel Karchin, who
