Overview and Goals of Grant
Global-scale information storage & accessIdentifying &
integrating relevant informationAny format & modalityNetworking
infrastructure
CISE Research Thrusts
23 faculty: 20 tenure track + 3 lecturers; ~12 involved in CISE
projects, but whole department uses infrastructureMultimedia

Infrastructure Equipment
CISE(CUCS) = research groups + infrastructureTwo generations of
LANs 100 Mb/s switched for every workstationCLIC teaching lab (Sun
+ Linux)File servers TB RAIDCompute clusters (Sun Linux)SGI Onyx 2
graphics server
Columbia CS Lab and Interactive Classroom
About 40 Unix workstationsCombinesMS/PhD research + project lab,
with multimedia capabilitiesTeaching lab, with TV/Internet video
studio for distance learningCompute cluster
CLIC
CLIC
Experiences with CLIC
Works well for recitation sectionsMost difficult: making local
students feel comfortableFaculty focus on cameraNeed to repeat
student questionsComputers in classroom distinctively mixed
blessing compete with email and web
CISE infrastructure: Staff
Support servers, CLIC, networksMaintain software
infrastructureProvide training for undergraduates
CISE outcomes - Leverage
Encouraged Microsoft equipment gift of $1M for Win2K teaching +
project labCaused $100k/year from provosts officeVisibility school
support for 1 FTEINTEREST networking lab
CISE outcome - CLIC
Undergraduate researchMS studentsMultimedia I/O equipment for
variety of classes (visual interfaces, adv. Internet services,
operating systems, )Local control of software and hardware
infrastructure vital for non-standard projects and coursesBetter
ability to teach programming recitations
MAGIC: Multimedia Abstract Generation for Intensive Care
Voice: . . . . Ms. Jones is an 80 year old, diabetic, hypertensive,
female patient of Dr. Smith undergoing CABG. . . .
Recovering 3D Models of Urban Structures
Success + Failure
Wide variety of research results, from media acquisition, to
transport/communication, to content generation and
processingIntegration across research efforts difficult, since
research part of many NSF/DARPA/industrial projects
More or Different Resources
More staff supportNeed cross-project programming and system
supportCost of equipment , cost of staff Plan for equipment
lifetime of 3 years
