Have you tried it on?
Glass is Google’s wearable computer that sits on your right ear and displays its contents through a tiny prism projector screen over your right eye. (duh)
During this summer break, CIS had a test-out event of a Google Glass loaned from the Claremont Library for two weeks. Soon after the announcement for the event, several people (six faculty, seven staff, and six students) with exceptional curiosity jumped right in. At Harvey Mudd, we like scientific experiments. So in this case, the hypothesis to accept (or otherwise sadly reject) was “Google Glass helps teaching and learning (in a way).” (Hey Google, isn’t Harvey Mudd a perfect place for testing such an emerging technology in higher ed? Contact us if you want to donate a Google Glass or two. ;))
Anyway, those 18 enthusiastic experimentalists came back with their personal opinions after trying Glass out for two to three hours. Two common responses were “It’s cool!” and, interestingly, “It made my head and eyes hurt.” A group of MyCS students tried it for a scavenger hunt using Glass apps like Word Lens for a group of teachers and reported that it went really well–this was actually a great use case for Glass in an educational setting. In addition, a couple of faculty members noted that the usefulness in teaching and learning would be dependent on the Glassware you use.
In fact, the default functions of Glass are pretty basic: google something, take a photo, record a video, get directions to, and send a message to, etc. But my 13-year-old son’s first command for Glass was “OK Glass, shoot a laser beam!” Unfortunately (and fortunately to me) it didn’t shoot a laser beam on me. It, however, could’ve done that if he had installed a Glass app doing it (at least on its screen). And it could’ve been educational (in a way) like showing how to calculate the power density of different laser beams depending on parameters like the beam diameter and the distance from the object. So as our faculty members noted in their feedback, with the right Glassware, it may be useful for education in near future.
P.S. We couldn’t accept or reject the hypothesis due to the small sample size. Google, we are eager to do more experiments and you know what to do.
CIS is very excited to announce the post-spring break events specially hand-picked for you. We have three scientific computing seminars lined up for the week of March 24th and April 1st. If you are interested, please pick one or two (or even all three) and register online to reserve your seat. Please find the details below:

893,000 SUs (Service Units = wallclock runtime multiplied by the number of cores) on several supercomputer facilities are now available to our researchers, faculty and students free of charge. In our ongoing efforts to provide a spectrum of high-performance computing resources to our community, CIS has signed up to participate in the XSEDE Campus Champion program and received almost 900 thousand SUs from national supercomputing centers. The SUs can be used to test various scientific applications that our faculty and students run for their research projects or for their classes. The Campus Champion at HMC will help install, set up, and test research applications on different facilities and provide any necessary on-campus support for using the XSEDE resources. The Campus Champion at Harvey Mudd is the Scientific Computing Specialist, Dr. Jeho Park at CIS.
What is XSEDE?
The Extreme Science and Engineering Discovery Environment (XSEDE) is the most advanced, powerful, and robust collection of integrated advanced digital resources and services in the world. It is a single virtual system that scientists can use to interactively share computing resources, data, and expertise. Scientists and engineers around the world use these resources and services—things like supercomputers, collections of data, and new tools—to make us all healthier, safer, and better off. XSEDE, and the experts who lead the program, will make these resources easier to use and help more people use them. Click here for more information.
What does the XSEDE Campus Champion Program do for Harvey Mudd?
The Campus Champion Program at HMC will serve as a:
- Source of local, regional and national high-performance computing and cyberinfrastructure information on our campus
- Source of information regarding XSEDE resources and services that will benefit research and education on our campus
- Source of start-up accounts on your campus to quickly get researchers and educators using their allocations of time on XSEDE resources, and
- Conduit for the campus high-performance computing needs, requirements and challenges, with direct access to XSEDE staff.
With the XSEDE Campus Champion allocations, HMC can now offer easy access to various supercomputers so that our researchers can test their applications and experience the benefits of using the supercomputers. Once the applications are tested, the Campus Champion will help the researchers get a “Startup” allocation (up to 200,000 SUs) which may be used up by the researchers (or the research team) for a year. If the research project needs more time and allocations, the PI(s) of the project will then be helped to apply for a “Research” allocation that is usually a multi-year allocation with a substantially larger amount of SUs than the Startup allocation. All these resources are provided to the researchers with free of charge by the NSF-funded XSEDE program. The Campus Champion at HMC is the local person who can help our researchers take the opportunity more easily. So please feel free to stop Jeho in a hallway and ask about the XSEDE Campus Champion Program. You are also welcome to contact our Helpdesk (firstname.lastname@example.org) for any inquiries about the XSEDE resources.

(Disclaimer: Sorry gamers. These GPUs are not for 3D gaming, but for number crunching scientific calculations!)
CIS submitted a proposal to NVIDIA’s Academic Partnership Program on the last day of May. NVIDIA quickly approved the proposal on June 11 and decided to donate us two Tesla C2075 GPUs (MSRP $2,500 per piece). Although it took a month to process the shipment at NVIDIA’s distribution center due to their high demand, it was worth the wait!
As of this writing, Tesla C2075 is the top-notch GPU available on the market for GPU computing. It has 448 CUDA cores and 6GB GDDR5 memory, which allows to pull 515 Gflops in double precision calculations and 1030 Gflops in single precision. Yup, it’s a little monster and we’ve got two of them!
CIS (Andy Davenport and Jeho Park) has been collaboratively working with Prof. Vatche Sahakian at Physics on a pilot project to prepare a new high performance GPU system on our campus. Prof. Sahakian generously offered to purchase a high-end GPU host computer. CIS is providing the NVIDIA GPUs and technical support to build a new system. Once the setup is complete, the new system will be tested and later shared with faculty and student researchers at Harvey Mudd for high-performance GPU computing experiences and tests. If you are interested in GPU computing or wish to involve in the GPU computing pilot, please contact Jeho Park at CIS for more information (or leave your comment to this post).
