Yellowstone installation progress and schedule update

July 23, 2012
CISL and IBM have made enough progress on the installation of Yellowstone that we can now provide more accurate information about the likely schedule for acceptance and availability of NCAR's new petascale system.

Nearly all Yellowstone hardware has been delivered and is being assembled in the NWSC machine room. In a major milestone, on July 5, Yellowstone was completely powered on. While no significant problems arose, a number of hardware issues have been noted and are being addressed. The number of hardware issues are well within expectations for a system the size of Yellowstone. IBM and CISL are continuing to install software and configure the administrative and user environments. We are now estimating that the installation activities will be completed by the end of July.

At that point, IBM and CISL will jointly conduct benchmarks and run the system with a simulated workload around the clock for three weeks, a period called the Acceptance Test Period (ATP). If Yellowstone successfully completes the acceptance tests, CISL will take over the system from IBM, and we expect at least two additional weeks for NCAR-specific configuration and customization, which may involve clearing all data from the new disk system (several times) to optimize file system performance.

Our best estimate for completing these activities pushes the start of Accelerated Scientific Discovery (ASD) projects to early September. The rest of the user community will have access as soon as practical after the ASD projects begin.

We will keep you posted as we proceed, particularly about significant changes in this schedule. Please contact with any questions.
