Acceptance testing on the new Summit supercomputer is complete and the Early Science Program will ramp up over the next few weeks.

The OLCF has now completed acceptance testing on the new Summit supercomputer and will begin ramping up the Summit Early Science Program over the next few weeks.  Most immediately we have provided the Center for Accelerated Application Readiness (CAAR) teams access to Summit to complete work needed to satisfy key performance metrics required to meet Summit project targets. As these projects transition into the early science phase of their proposed work we will begin enabling the Early Science Projects that have been approved for Summit access based on internal OLCF review and resource availability. Formal proposal decision notifications have now been sent in response to all Early Science Program submissions.

Overall, approximately 5 billion equivalent Titan core hours will be allocated to this program, which is equal to over one year of dedicated Titan system access. We expect that all approved projects will be enabled by early January.
