ASCR Requirements Review 2012


The goal of this review is to accurately characterize the current and future networking requirements of science conducted using the ASCR supercomputer centers - ALCF, NERSC, and OLCF. In particular, we are interested in network-intensive science programs that will need to be supported by the ASCR supercomputer centers regardless of whether particular users receive allocations in a given year, or programs that have significant investments in computational resources that are likely to be continued for some time.

These requirements will serve as input to the ESnet architecture and planning processes, and will help ensure that ESnet continues to provide world-class support for scientific discovery for DOE scientists and their collaborators. The tangible outcome of the revew will be a document that includes both the network requirements and a supporting narrative.


The review will be a 1.5 day event - all day Thursday October 4th 2012, and the morning of Friday October 5th, 2012.  

Review Registration

Attendance at this review is by invitation only - no registration is required.

Network Requirements Document for the Advanced Scientific Computing Research Program

This review will generate a network requirements document for the ASCR Program Office. This document will be composed of the network requirements input from the review attendees.

Review attendees should review the case study template document and other background materials on the documents page. Please also consult the pages on the ESnet public web site.

Please then use the background materials in combination with your own knowledge and experience to generate a narrative describing your scientific research, instrument, facility or other scientific endeavor. Examples of science narratives with their accompanying requirements matrices can be found in the reports from previous reviews. Please send your case study (narrative and corresponding data table) to Eli Dart (, Lauren Rotman (, and Brian Tierney ( no later than one week before the review.

At the review we will discuss the case study documents with the attendees to ensure that we understand the science being done insofar as it has an impact on networking. We will also make sure that we capture the timelines for upgrades, new facilities, changing collaborations, and other coming events that will change the way in which the network is used.

The review format is much closer to a round-table discussion rather than a series of PowerPoint presentations. If you feel that you really need to give a formal presentation we can probably accommodate that, but we have found that these reviews are more productive if there is a simple discussion and exchange of ideas rather than a formal presentation format.



The review will be held in the DOE offices at Germantown. The address is:
19901 Germantown Rd.
Germantown, MD 20874.

The review will run all day on Thursday, October 4 and the morning of Friday October 5, 2012.

There is no designated hotel for the review - attendees are encouraged to contact nearby hotels regarding room rates and availability.

Video Conference Info

Video conference coordinates will be posted here when they are available.

The Germantown building has a cafeteria - information is available on the DOE web site (opens in new window).


Note - In consideration of remote attendees in other time zones, case studies will be done in time zone order, East to West:

  1. OLCF
  2. ALCF
  3. NERSC
