2015 OLCF Users Meeting: Reaching for the Summit Together

Reaching for the Summit Together

The Oak Ridge Leadership Computing Facility (OLCF) is pleased to announce that the 2015 OLCF User Meeting will be held June 23-25, 2015, at Oak Ridge National Lab in Oak Ridge, TN. The purpose of this user meeting is to share selected computational science and engineering achievements emerging from OLCF’s user programs, to enable direct interactions among users, advance OLCF’s relationships with our user community and highlight their computational requirements for the future.
The meeting will feature paired talks from OLCF users and application developers. This is an opportunity for users to share their scientific accomplishments and state-of-the-art computational development methods. The agenda also includes a poster session where all OLCF projects are encouraged to share their achievements with the OLCF community. A new program element will be user-led “Birds-of-a-Feather” sessions to advance direct user communication. OLCF staff look forward to engaging the user community by discussing current and future projects at our center.
On the day prior to the Users Meeting, there will be a short training session for new users to our center. This afternoon workshop will introduce to you the User Assistance team and help you get started at our center. You’ll get important information on the basic workings of our resources and valuable tips and tricks to help you run successfully

Attending via Webinar:  For participants who cannot attend on-site, a BlueGene event has been set up.  Please follow instructions below to attend:

[tab:  Hotel and Bus Information]

Bus:  An ORNL 36 passenger bus and 12 passenger van will be picking attendees up at the DoubleTree Hotel (7:00 – 7:20 a.m.) and at the Staybridge Inn and Suites (7:25 – 7:40 a.m.).  If you are not staying at either of these hotels, you can drive to either hotel to catch a ride on the bus.

ORNL Guest House:  Regretfully, you cannot make a reservation at the ORNL Guest House because this is classified as an Open-to-the-Public Meeting.  There are a number of nice Oak Ridge hotels listed below.  We will be running a bus service to the DoubleTree and Staybridge Suites.  If you are not staying at either of those hotels, you are welcome to catch the bus at one of these locations.
