Who’s using nanoHUB.org? Over 90,000 users past 12 months Launched 394,000 simulations

Typical Web-based Simulations Started at Purdue 1995 with PUNCH: »Enabled researchers and students to access real simulation codes »traditionally 800 users annually. Typical usability is marginal Codes are typically out-of-synch with web version Typical Questions: What was my input? Did I enter things right? Symptoms of: No VISUAL feedback. Not interactive. The OLD static GUI Form sheet input Batch submission Output in some file Visualize a gif image Other output file Visualize gif image

The nanoHUB has proven itself to be an extremely valuable tool for education and research. …We have used the Resonant Tunneling Diode simulator and the MSL simulator on the nanoHUB for homework exercises and mid-term exams. A class survey of the use of the nanoHUB simulation engines had shown that the experience is quite positive. The staff at the nanoHUB has been very responsive in supporting our class activities in a professional manner. H.-S.
