High Performance Computing
Interview with David Frioni, Yale ITS, HPC Site Manager
By Lisa M. Maloney
I sat down with Dave Frioni to uncover the mysteries of High Performance Computing. These are some excerpts from that chat:
What is HPC . . . really?
"High Performance Computing is basically the ability to run computations across many processors in parallel instead of having all the computations performed on a single processor. This has the advantage of dramatically reducing the time it takes to achieve results."
When and why did it become necessary?
"When is hard to answer. There is research that has been leveraging high performance computing for a long time. There are also many disciplines that are just recently realizing that HPC can provide them with huge advantages as well."
What are your biggest challenges?
"One of our biggest challenges currently is keeping pace with deploying and supporting the massive amounts of data storage required for today's research."
Is storage the right word to use?
"Yes, high performance storage is a big component of most HPC clusters, as are processing cores and networking."
Why do people need to know about HPC?
"It can provide a tool to dramatically reduce the time it takes to achieve results, thus, allowing much more research to be performed in a shorter period of time."
What is the basic difference between regular Data Center storage and HPC storage?
Can we make a simple comparison, so the lay person understands the concept of a billion terabytes of space!
"A billion terabytes is beyond what is realistic today. A good lay person comparison is:
1 million gigabytes = ~1 petabyte
1 thousand terabytes = ~1 petabyte
Many people are still walking around with 1-gigabyte USB flash drives. Many people buy a 1-terabyte USB drive to backup their home computer or to store pictures and music collections on. However, it is not only about the amount of storage, it is about the speed at which the devices can read and write data."
Give me the Wikipedia version of this technology that is not too technical!
"High Performance Computing started over 30 years ago and consisted of purpose-built proprietary systems--supercomputers. These systems do still exist, but have typically been cost prohibitive for common research efforts.
In the 1990s, off the shelf-computer systems and networking technologies, combined with advances in software, matured enough to be able to string a bunch of these together and significantly increase computing performance at a fraction of the cost of a proprietary supercomputer. This trend has continued and most of the fastest computer systems today are modeled after this design."
When I walk through the center it reminds me of an episode of the TV sci-fi series the X-Files.
"I have never watched an episode of X-Files. Much of the technology used in distributed HPC clusters is COTS or commercial off-the-shelf and are the same hardware used in common data centers, but at a much larger scale. HPC tends to be early adopters to technologies that offer performance. Unlike enterprise data centers, advantages gained in performance typically outweigh the maturity or stability of the technology. HPC likes to push the envelope, while enterprise requires pure stability and uptime."

Yale School of Forestry Students at West Campus
Forestry students assess the West Campus landscape.
Last semester, the School of Forestry offered two landscape management courses that focused on the West Campus grounds--Ecological Urbanism and Management Plans for Protected Areas.
The management plan seminar, taught by Professor Mark Ashton, had four forestry students walking and closely observing the West Campus grounds--documenting land use, researching land history, zoning and mapping. They assessed soils, vegetation, wildlife habitat and surveyed West Campus faculty, staff and students. After collecting and analyzing all their data, the students developed a land management plan for the forest, adjacent undeveloped green areas and some developed areas (i.e., parking lots) at West Campus.
Their assessment took several months and began with a walking tour of the entire campus. They then met with key stakeholders to understand the different perspectives and goals for the property. Next they gathered input from West Campus administration, community education, and grounds maintenance.
Part of the overall land assessment includes separating the property into "stands." To do this, they identified tracts of land that have commonalities. They were surprised by the ecological diversity of the campus. "For instance, one stand is a very young forest (20 years old), whereas another stand is a very old forest. Another younger stand had very few trees, and instead had mainly herbaceous species and shrubs. Yet another stand was a wetland," says Andrew Breck, MF '11. The distinctions are based on: soils, hydrology, vegetation, past land use, and topography.
In mid-December, the students presented their findings and offered over 20 recommendations for land use and storm water management. A few of their top recommendations include: maintaining and enchancing the wild meadows and scrub lands on West Campus; designating minimally maintained lawn areas (i.e., no-mow zones); increasing the number of picnic tables and outdoor community spaces; and extending the current trail system. We've invited the students to present their land management plan at a West Campus Brown Bag Lunch and hope to have that scheduled soon.

The students wanted me to extend a "VERY BIG THANK YOU" to all the folks at West Campus who helped them gather all the data needed for their assessment and land management plan.
New and Improved Support Services
New Automated On-site Freezer Program
Administrators from West Campus, the Yale Stockroom and Yale Procurement teamed together to bring this new program to West Campus. West Campus researchers now have immediate, on-site, 24-7 access to Roche reagents, including molecular, cellular analysis, genomics, protein expression, end-point PCR, real-time PCR and enzymes. To use this service, register at https://login.roche-prime-supply.com. After registration, a user name and password will be provided. Placing an order is simple. You will have real-time access to inventory and be able to procure any Roche reagent either from stock or on special order. Convenient ordering online from your bench or desk, and for pick up just walk to the basement of WB-24 where the freezer is located. Use this program for better pricing and free shipping. For more information on the program, please email firstname.lastname@example.org.
Improved West Campus Purple Line Shuttle Schedule
Working with several focus groups consisting of shuttle and non-shuttle users, we recently updated our West Campus Shuttle Schedule. One major challenge when designing this new schedule was the purple line does not run in a loop. At 8 a.m., purple line shuttle #1 leaves Lot 22/Science Hill and Purple Line #2 leaves West Campus. Until 6:30 p.m. Monday to Friday they pass each other on I-95 going in opposite directions. If this sounds confusing, it was challenging to represent it visually. With the help of Yale Printing and Publishing Services Designers--Peter Johnson and Lynne Reichentahl--our new shuttle schedule is easier to read and understand, especially for those new to Yale.

|West Campus Peabody Community Education Center|
Winter Update from Tom Parlapiano.
- While weather related school cancellations have forced many of our classes to be rescheduled, the Peabody Education Center has been able to sneak in a few 3rd grade classes from West Haven's Mackrille and Forest Elementary schools to debut their Rocks & Minerals Program. "It has received high marks from teachers, especially the hands-on lab segment in which students test various minerals to determine their properties," says Program Coordinator Tom Parlapiano.
- The Connecticut Natural Science Illustrators have begun their second session of classes on Wednesday afternoons and Saturday mornings for adults of all skill levels. Current offerings include Fundamentals of Natural Science Illustration and Botanical Illustration in Watercolor.
- Summer Camp registrations have begun! The Community Education Center will host three weeklong camps this year, followed by a weeklong institute for Science Pathways students from New Haven area middle and high schools. Camps begin August 1st. Information and on-line registration can be found on the Peabody Museum's Events webpage at http://www.peabody.yale.edu/events.
