Cray X1 Review

February 10-11, 2004

Background:

Lodging in Oak Ridge Comfort Inn 433 S. Rutgers Avenue Oak Ridge, TN 37830 (800) 553-7830 (865) 481-8200 Block name: ORNL/CrayX1 Review

The Office of Science, through its Office of Advanced Scientific Computing Research (ASCR), is investigating the performance of the Cray X1 computer for capability-limited science applications. This evaluation is being conducted by the Center for Computational Sciences (CCS) at Oak Ridge National Laboratory. See http://www.ccs.ornl.gov/Phoenix.html for more information.

Charge:

1. Review and analyze what is currently know about the performance of the Cray X1 on capability-limited science applications. Draw on all available information from all Cray X1 installations.
2. Based on this analysis, inform ASCR on the relative suitability of the Cray X1 to the science problem set of the Office of Science:
   • For which applications is it well-suited?
   • For which applications is it ill-suited?
3. Inform ASCR on the expected performance of larger X1 installations and their potential impact on capability-limited science applications.
4. Review the evaluation process currently being used by CCS and recommend improvements, if necessary.

Review:	February 10-11, 2004
Preliminary Report:	February 11
Final Report:	February 27
