NERSCPowering Scientific Discovery Since 1974

Data Day 2016

August 22nd - 23rd, 2016

Wang Hall (LBNL Building 59) and Building 50 Auditorium
Lawrence Berkeley National Laboratory

This summer, NERSC will host a brand new, data-centric event, Data Day. The main event will take place on August 22, followed by a half-day hackathon on August 23. The goal: to bring together researchers who use, or are interested in using, NERSC systems for data-intensive work.

On August 22, a full day of talks and tutorials will get you up and running with the latest data-focused tools for scientific computing. Training sessions on machine learning, Python, Spark, the Cori Burst Buffer, and science gateways will be complemented by presentations from scientists already taking advantage of these tools in their own research. A poster session will highlight work and work-in-progress that uses NERSC resources for experimental and observational science. 

Stick around for the hack day, and you’ll get a chance to put your new knowledge to work creating a custom workflow. We’ll start off the half-day hackathon with an introduction to building workflows with Python and Spark, then provide local experts to help you get coding. The entire event will be held on site at the lab, in the Building 50 Auditorium and in Wang Hall, NERSC’s new landmark building at Berkeley Lab. Come and learn how to power up your data.

  • Talks will be held in 3101 - but for those who would rather hack than attend a talk we will also have room 3104 for all-day hacking. 
  • A NERSC account will be needed to get the most out of the hacking. 
  • NERSC staff will be on hand to help out with your questions on the day.

Lawrence Berkeley National Laboratory is a multidisciplinary national laboratory located in Berkeley, California on a hillside directly above the campus of the University of California at Berkeley. The site consists of 76 buildings located on 183 acres, which overlook both the campus and the San Francisco Bay. »More Visitor Information.


All attendees are invited to bring a poster for display at Data Day. Please indicate whether you will do so on the registration form so that we know how many poster spaces to reserve. We will encourage attendees to hang their posters when they arrive in the morning so that others can view them throughout the day. We will also ask poster presenters to stand by their posters for the first half hour of the evening poster session. Please size your poster to no larger than 36 in. x 48 in, and leave it unmounted. We will provide means to hang it, including hardware.

Site Access

All non-LBNL participants must register. Those attending in person will need to obtain a visitor bus pass or parking pass in advance.  Indicating on the registration form that you will attend in person will initiate the request. We recommend carpooling, shuttle and taxi. Check-in with Security and picture ID is required for on-site attendance.

LBNL Security requires the names, citizenship and country of birth of all visitors, including those attending remotely.  If you have questions, please contact Zaida McCunney. 

The Blackberry Canyon entrance is closest to Wang Hall and Building 50. The shuttle buses stop at building 65, which is the main shuttle bus stop (across the street from the driveway to Wang Hall and the stairs to Building 50).

Parking at LBNL is limited due to a number of construction projects. We recommend car pooling, LBNL shuttle, or taxi. If you drive, a parking space may be reserved.  For those visitors who plan to drive to LBNL, we will reserve general parking near Wang Hall.

Shuttle Information

There is an LBNL shuttle bus from various locations around the City of Berkeley, including near the Downtown Berkeley BART station.  If you plan to take the LBNL shuttle, you are required to have an LBNL Visitor Bus Pass  (requires advance notice) and picture ID to show the bus driver. 

Bay Area Rapid Transit Train (BART)

The Downtown Berkeley BART station is two short blocks from the LBNL shuttle line on the corner of Addison and Shuttuck.  The LBNL Blue Uphill Shuttle Bus will take you to the Blackberry Canyon entrance and the CRT Building.  The CRT building is across the street from LBNL's main bus stop. »BART Web site
